Write a program CountWords in Java that reads text from a file and b.pdf
Write a program CountWords in Java that reads text from a file and breaks it up into individual
words. Insert the words into a tree set. At the end of the input file, print all words, followed by

the file is not found, give the user a chance to select another file.

Instruction
You’ll probably want to import FileReader, PrintWriter, ArrayList, List, and Scanner.
For this assignment, keep all your classes in one file. Leave the Hwk8 class as public and don’t
use an access modifier for the other classes..
One suggestion for the order to implement the classes would be: the three Exceptions,
Dictionary, Template, and finally the Driver (main method).
You will need to generate the input text files manually from the sample runs of the program.
Exceptions:
The implementation of all three of them (DictionaryFormatException,
EmptyWordListException, and UnsupportedCategoryException) should be very similar.
Since they are all run-time type exceptions, they can extend the RuntimeException class.
You can provide a specific error message to pass into each of them while you are generating the
exceptions in the other classes.
Dictionary:
The instance variables of the Dictionary class are Lists of type String to store the following types
of words: nouns, verbs, adjectives, adverbs, pronouns, interjections. Using an ArrayList to
implement the Lists is recommended.
addWord: The input should be from the “words” file. Specifically it will have the format
“partofspeech:word”. Think about String methods you may use to format the input properly
before using it. Then consider what all these inputs should have in common to determine a
delimiter (character) for splitting the String. You should also check if the input line is empty
(skip it in this case) or whether there isn’t exactly two parts split from the String (in this case
throw a DictionaryFormatException). Trim the resulting two Strings at this point, and use their
data to determine which ArrayList the word belongs to before adding it to that list.
getWord: The input is a String representation of the part of speech list you want to extract a word
from. If the String does not correspond to a part of speech name (noun, verb, etc.), throw an
UnsupportedCategoryException. First make sure there are words remaining in the selected list. If
not, throw an EmptyWordListException. Finally, use a random function to randomly remove a
word from that list and return it as the output.
Template:
Its sole instance variable is a String called template. This should be the String equivalent of the
template file the driver reads in.
As such, the constructor should just set the template value to be the String representation of the
template passed into it.
fill: Takes in a dictionary as an argument, and returns a String representation of a modified
template. You’ll want to find a way to split the template String into pieces easier to manage. To
create the result String, you’ll need to keep the parts of the String that aren’t word prompts as-is.
Then for the elements where “/ pos” shows up, you’ll want to replace those by retrieving an
appropriate word from the dictionary list (so choose from the noun list when a noun is requested,
etc.) if the process of appending parts of the String fails for s.

Parsing food data lab - Please answer in JAVA
Given a text file containing the availability of food items, write a program that reads the
information from the text file and outputs the available food items. The program first reads the
name of the text file from the user. The program then reads the text file, stores the information
into four separate arrays, and outputs the available food items in the following format: name
(category) -- description
Assume the text file contains the category, name, description, and availability of at least one food
item, separated by a tab character.
Ex: If the input of the program is:
and the contents of food.txt are:
the output of the program is:

words (separated by whitespace), and lines in that file. Then, it replaces each line of the file with
its reverse. For example, if the file contains the following lines (Test1.txt):
This is a test
Hi there
Output on the console:
Number of characters: 22
Number of words: 6
Number of lines: 2
Data written to the file (Test1.txt):
tset a si sihT

Solution
ReadFileCount.java
import java.io.File;
import java.io.FileNotFoundException;
import java.io.PrintStream;
import java.util.Scanner;
public class ReadFileCount {
public static void main(String[] args) throws FileNotFoundException {
Scanner scan = new Scanner(System.in);
System.out.println(\"Enter file name: \");
String fileName = scan.next();
StringBuffer finalsb = new StringBuffer();
File file = new File(fileName);
if(file.exists()){
int numberOfLines = 0;
int numberOfCharacters = 0;
int numberOfWords = 0;
Scanner scan1 = new Scanner(file);;
while(scan1.hasNextLine()){
StringBuffer sb = new StringBuffer();
String s = scan1.nextLine();
sb.append(s);
numberOfLines++;
numberOfCharacters = numberOfCharacters + s.length();
String words[] = s.split(\" \");
numberOfWords = numberOfWords + words.length;
finalsb.append(sb.reverse());
finalsb.append(\"\ \");
}
System.out.println(\"Number of characters: \"+numberOfCharacters);
System.out.println(\"Number of words: \"+numberOfWords);
System.out.println(\"Number of lines : \"+numberOfLines);
PrintStream ps =new PrintStream(file);
ps.print(finalsb.toString());
ps.flush();
ps.close();
System.out.println(\"Data written to the file \"+fileName);
}
else{
System.out.println(\"File does not exist\");
}
}
}
Output:

Java for Mainframers
The document discusses Java programming concepts including:
- Java provides a common framework to handle strings, networks, and extended functions. It also handles garbage collection and can be cross-platform.
- The main() method is where every Java program begins execution. It must have a specific signature of public static void main(String[] args).
- There are 8 primitive data types in Java including int, short, long, float, double, char, boolean, and byte that are used to store basic values.
Lecture - 2 Environment setup & JDK, JRE, JVM
This lecture describes how we set up the environment for executing Java Application and also describes the tools that are required. This lecture also contains a simple java program and the description.
Java basics
The document discusses the history and development of the Java programming language. It describes how James Gosling initiated the Java project in 1991. Sun Microsystems later released Java 1.0 in 1995 with the promise of "Write Once, Run Anywhere". Sun later released much of Java as open-source software in 2006 and 2007. The document also provides overviews of Java concepts like object-oriented programming, the Java Virtual Machine, and classloaders.
Description 1) Create a Lab2 folder for this project2.docx
Description
1) Create a Lab2 folder for this project
2) Use the main driver program (called Writers.java) that I provide below to write files of differing types. You can copy and paste this code, but make sure the spaces variable copies correctly. The copy and paste operation eliminates the spaces between the quotes on some systems.
3) In the writers program, fill in the code for the three classes (Random, Binary, and Text). In each class, you will need a constructor, a write method, and a close method. The constructor opens the file, the write method writes a record, and the close method closes the file.
4) Other than what I just described, don't change the program in any way. The program asks for a file type (random, binary, or text) and the name of the file to create. In a loop it inputs a person's name (string), a person's age (int), and a person's annual salary (double). It writes to a file of the appropriate type. The loop terminates when the user indicates that inputting is complete. The program then asks if another file should be created. If the answer is yes, the whole process starts again. This and all of the java driver programs should be saved in your lab2 folder but not in the cs258 sub-folder.
5) Note: The method signatures for accessing all of the three types of files (binary, random, and text) are on the class web-site. Go to power point slides and click on week two. This will help if you didn't take accurate notes in class.
6) Write a main program to read binary files (BinReader.java). This program only needs to be able to read and display records from a Binary file that was created by the writers program.
7) Write a main program to read random files (RandReader.java). This program only needs to be able to read and display records from a Binary file that was created by the writers program. Make sure that this program reads and displays records in reverse order. DO NOT USE AN ARRAY!!!
8) In your Lab2 folder, create a subfolder within lab2 named cs258. Download Keyboard.java from the class web-site to that folder. Add a new first line of Keyboard.java with the statement, package cs258;. This line will make Keyboard.java part of the cs258 package. The driver program shown below has an import ‘cs258.*;’ statement to access the java files in this package.
9) Modify Keyboard.java. We want to extend this class so it can be extended to allow access to multiple files. The changes follow:
a. Remove all static references. This is necessary so that there will be an input stream variable (in) in each object.
b. Change the private modifier of the in and current_token variables to protected. Change the private modifier to protected in all of the signature lines of the overloaded getNextToken methods.
c. Create a constructor that instantiates the input stream for keyboard input. Remove the instantiation from the original declaration line for the in variable. The constructor doesn't need any parameters.
10)Create a class TextR.

9.8 LAB: Parsing food data
Given a text file containing the availability of food items, write a program that reads the
information from the text file and outputs the available food items. The program first reads the
name of the text file from the user. The program then reads the text file, stores the information
into four separate arrays, and outputs the available food items in the following format: name
(category) -- description
Assume the text file contains the category, name, description, and availability of at least one food
item, separated by a tab character.
Ex: If the input of the program is:
and the contents of food.txt are:
the output of the program is:
import java.util.Scanner;
import java.io.FileInputStream;
import java.io.IOException;
public class LabProgram {
public static void main(String[] args) throws IOException {

Programming in Java
The document discusses key features of the Java programming language. It notes that Java is platform-neutral, meaning Java programs can be executed on any system without being tied to a particular hardware or operating system. It also mentions that Java is compiled and interpreted, object-oriented, multi-threaded, and has features like garbage collection. The document then provides an overview of the Java development environment and tools used like the Java Development Kit.
Java
Java is an object-oriented programming language that can create applications that run on multiple platforms. When a Java program is compiled, it produces bytecode that can run on any system with a Java Virtual Machine. The file must contain a public class that matches the file name and can include import statements for external libraries.

About java
- Java was originally created in 1991 by Sun Microsystems to develop a programming language that could be used to control various home entertainment devices from a single hand-held device. This led to the creation of Java, originally called Oak.
- Java is a cross-platform language that can run on various operating systems. Java programs can be standalone applications or applets that require a web browser to run.
- The Java compiler converts Java source code files with a .java extension into bytecode files with a .class extension. The Java Virtual Machine then executes the bytecode instructions.

What part of the brain is used in sympathetic arousal (ANS)Solu.pdf
What part of the brain is used in sympathetic arousal (ANS)?
Solution
Answer:
During danger or frightening situations, the body responds by increasing the heart rate and
raising the respiration rate. These are arousal responses which sets one ready to fight or flee.
The sympathetic nervous system is responsible for the arousal responses and prepares the body
to respond to such situations. This system works in coordination with the parasympathetic
nervous system which calms the body during arousal.
The sympathetic and parasympathetic nervous system together forms the autonomic nervous
system..

epithelial tissue if found lining the urinary bladder? What type of cell surface characterizes this
epithelial tissue? What is the function of this tissue there?
Solution
Answers:
Types of epithelial tissues:
1. (a) Simple sqaumous epithelium lines the air sacs or alveoli of the lungs.
(b) Simple squamous epithelium in the alveoli allow oxygen from the air to enter the blood in the
capillaries of the lungs. carbon dioxide is also eliminated from the body through the simple
squamous epethelial cells of the lung air sacs.
2. (a) Simple cuboidal epithelium
(b) The cells perform secretion and absorption in the kidney tubules and glandular ducts.
3. (a) Ciliated pseudostratified columnar epithelium are found in the airways of the respiratory
tract.
(b) They are characterized by the presence of cilia and secretion of mucous which collect foreign
materials and help to cough or sneeze them out.
(c) It helps to moisten and protect the airways by acting as a protective barrier pathogens and
foreign antigens through mucociliatory action.
4. (a) Intestinal epithelium forms the lining of both small and large intestines. It is composed of
simple columnar epithelial cells.
(b) These cells are characterized by the presence of circular and transverse folds, villi and
microvilli.
(c) It acts as a protective barrier to foreign antigens and toxins and also acts as a selectivity filter
to facilitate the uptake of dietary nutrients.
5. (a) Stratified squamous epithelium is found on the surface of skin.
(b) They may be keratinized or non keratinized.
(c) Its main function is protection from wear and tear.
6. (a) Transitional epithelium
(b) They may be cuboidal or columnar. When the tissue compressed, the cells become stretched.
During such conditions, they appear to be irregular and squamous.
(c) They can stretch and allow for the accommodation and storage of fluid in the urinary bladder.
It also acts as a barrier between the lumen and the blood stream..

What part of the brain is used in sympathetic arousal (ANS)Solu.pdf
What part of the brain is used in sympathetic arousal (ANS)?
Solution
Answer:
During danger or frightening situations, the body responds by increasing the heart rate and
raising the respiration rate. These are arousal responses which sets one ready to fight or flee.
The sympathetic nervous system is responsible for the arousal responses and prepares the body
to respond to such situations. This system works in coordination with the parasympathetic
nervous system which calms the body during arousal.
The sympathetic and parasympathetic nervous system together forms the autonomic nervous
system..

Solution
Answers:
Types of epithelial tissues:
1. (a) Simple sqaumous epithelium lines the air sacs or alveoli of the lungs.
(b) Simple squamous epithelium in the alveoli allow oxygen from the air to enter the blood in the
capillaries of the lungs. carbon dioxide is also eliminated from the body through the simple
squamous epethelial cells of the lung air sacs.
2. (a) Simple cuboidal epithelium
(b) The cells perform secretion and absorption in the kidney tubules and glandular ducts.
3. (a) Ciliated pseudostratified columnar epithelium are found in the airways of the respiratory
tract.
(b) They are characterized by the presence of cilia and secretion of mucous which collect foreign
materials and help to cough or sneeze them out.
(c) It helps to moisten and protect the airways by acting as a protective barrier pathogens and
foreign antigens through mucociliatory action.
4. (a) Intestinal epithelium forms the lining of both small and large intestines. It is composed of
simple columnar epithelial cells.
(b) These cells are characterized by the presence of circular and transverse folds, villi and
microvilli.
(c) It acts as a protective barrier to foreign antigens and toxins and also acts as a selectivity filter
to facilitate the uptake of dietary nutrients.
5. (a) Stratified squamous epithelium is found on the surface of skin.
(b) They may be keratinized or non keratinized.
(c) Its main function is protection from wear and tear.
6. (a) Transitional epithelium
(b) They may be cuboidal or columnar. When the tissue compressed, the cells become stretched.
During such conditions, they appear to be irregular and squamous.
(c) They can stretch and allow for the accommodation and storage of fluid in the urinary bladder.
It also acts as a barrier between the lumen and the blood stream..
Which bond would be most polar whySolutionstarting with .pdf
Which bond would be most polar why
Solution
starting with F that is the most polar element, we should start analising this. N-F and C-F have
the same polarity because the polarity of C and N is the same according with the periodic table.
So analising F-B and getting that B have more polarity that C and N result that the bond with
most polar in the answers is F-B. Remember how to find the polar according the table..

What is James Wilsons leadership style and traits What made him dif.pdf
What is James Wilsons leadership style and traits? What made him different from other founding
fathers?
Was he a change agent? If so, how did he help their followers through change?
What type of power did james wilson possess?
Did he demonstrate ethics and values, if so, how?
What risks did he take?
Solution
James Wilson was a democratic leader. This can be cnfirmed by the decisions taken by James
Wilson during the American Revolution. During the revolution Mr. Wilson advocated for the
independence of colonies in America from the British empire. When the time for voting for
independence from the British empire came Mr. James Wilson proposed that he must consult and
take the views of public in his constituent before taking any decision. This process delayed the
independence of the Philadelphia constituency. Ultimately the people of his constituency agreed
to get independence and they voted in favour of independence. Thus, the leadership style adopted
by Mr. James Wilson has a democratic leadership style.
The democratic style adopted by Mr. James Wilson made him a different leader as compared to
other founding fathers.
Yes, he was a change agent. He argued for independence of his constituen from the Bristish
empire and advocated furiosly for their independence. He asked the people of his constituent for
their opinion about getting independence from the British empire but the people of his
constituent resisted independence. He waited and explained to them about the benefits of getting
independence. Eventually the people of his constituent decided to get independence from the
British empire and hence Mr. James Wilson voted in favour of independence.
James Wilson possessed great debating and advocating skills with strong emphasis on giving
logical reasoning in the debate..

The method FRET ALEX is a more precise way to determine the number o.pdf
The method FRET ALEX is a more precise way to determine the number of interacting
molecules and the orientation of the fluorophores. In this method, both donor and acceptor
fluorescent molecules are excited and emission light is measured. The donor molecule is excited
then the acceptor molecule is excited in an alternating pattern with lasers. The light is measured
within a very small space - so small only one set of molecules can fit. They can tell if donor and
acceptor are together or separate even though they may not be close enough for FRET alone or
the fluorophores are facing away from each other. What result would lead to the conclusion that
sigma subunit remained associated with the elongation complexes? The answer has to do with
fluorescence.
Solution
While using this method the distance between the Sigma subunit and the protien complex
molecule is measured using the Forster Resonance Energy Transfer (FRET) which utilises the
distance-dependent interaction of two fluorophores to detect proximity or/and changes in the
fluorophore interactions. It has been found that during the biochemical process of protien
enlongation this distance does not change significantly thus providing evidence that the subunit
remains associated with the elongation (Protien ) Complex..

The following expression was simplified incorrectly. In which line er.pdf
The following expression was simplified incorrectly. In which line error first made when
simplifying the identity shown below? 1 + sec(-theta)/sin(-theta) + tan(-theta) = 1 - sec theta/sin
theta - tan theta = 1 - sec theta/sin theta [1 - (1/cos theta)] = 1 - sec theta/sin theta (1 - sec theta) =
1/sin theta = csc theta
Solution
we know that sin(-theta) = -sin (theta )
hence the mistake was first identified in the line 1.
The energy used in the CaMn cycle for the production of carbohydrate .pdf
The energy used in the CaMn cycle for the production of carbohydrate molecules comes from
A. ATP B. NADPH C. H2O D. A & B E. A, B, and C During photosynthesis, photons raise
electrons to higher energy levels. These excited electrons are obtained from what compound?
CO2 Glucose ATP Chlorophyll H2O CAM plants keep stomata closed in daytime, thus
reducing loss of water. They can do this because they They use Photosystems at night They fix
CO2 Into sugars in bundle-sheath cells They use phosphofructokinase, which outcompetes for
rubisco for CO2\" They fix CO2 Into organic adds at night They fix Co2 into pyruvate
Solution
Question 4
Correct option- A) ATP
Explanation: If we study the role of the compounds then the answer will be cleared.
ATP- It acts as energy source by losing one energy rich phosphate. ATP provides energy for the
regeneration of RuBP.
NADPH- Though it is a high energy rich compound but during Calvin cycle it acts as a reducing
agent. NADPH provides a hydrogen ion for the reduction of 3-phospho-glycerate into
glyceraldehyde-3-phosphate.
H2O- Calvin Cycle Synthesizes Hexoses from Carbon Dioxide and Water.
Question 5
Correct option- H2O
Explanation- If we study the electron transport chain of photosynthesis then the route of electron
will be cleared.
The main process that generates electron is known as water splitting. Oxygen evolving complex
is a protein which split water and it is associated with photosystem II . By splitting of water ½
O2 and 2H+ are generated. And 2electron is liberated. Electrons are then passed to reaction
centre of chlorophyll..
The CAN-SPAM Acta. applies to virtually all promotional e-mails,.pdf
The CAN-SPAM Act
a. applies to virtually all promotional e-mails, whether or not the sender has a pre-existing
relationship with the recipient.
b. requires senders of promotional e-mails to provide a valid return address, which may be a
post office box or a specific physical location.
c. requires recipients of unsolicited, pornographic e-mails to notify the Justice Department.
d. requires senders of promotional e-mails to offer an opt-in system to recipients.
The Electronic Communications Privacy Act of 1986 is a federal statute that regulates email.
True
False
The amendments to the U.S. Constitution protect the people from the power of state and federal
governments.
True
False
Solution
The CAN-SPAM act sets national standards for sending commercial e-mails. In this question the
answer is option \"b\" - equires senders of promotional e-mails to provide a valid return address,
which may be a post office box or a specific physical location.
The CAN SPAM act has to adher to content compliance ans as per it a legitimate physical
address of the publisher and/or advertiser is present. PO Box addresses are acceptable in
compliance with 16 C.F.R. 316.2(p) and if the email is sent by a third party, the legitimate
physical address of the entity, whose products or services are promoted through the email should
be visible.
The Electronic Communications Privacy Act of 1986 was formed to protect all communications
and consumer records and includes the following types of electronic communications - transfer
of signs, signals, writing, images, sounds, data, or intelligence of any nature transmitted in whole
or in part by a wire, radio, electromagnetic, photoelectronic or photooptical system.
The answer is \"false\" as the act looks not only at e-mails and regulates them but also radio,
phone messages etc.
The tenth amendment to the U.S. Constitution states that the federal government possesses only
those powers delegated to it by the Constitution. All remaining powers are reserved for the states
or the people. So the answer is \"true\"..
SensesFor each of the special senses, understand how a stimulus is.pdf
Senses
For each of the special senses, understand how a stimulus is received and then transmitted to the
brain
Solution
Special senses are the senses that have specialised organs devoted to them like vision (eye),
hearing and balance (ear) , smell( nose) , taste( tongue). Information from special senses is
carried in special somatic afferents and special visceral afferents.
Taste sensation: Chemoreceptors located in the taste buds of the tongue;
a. they detect chemicals present in food and in saliva
b. Sweet, sour, bitter and salty are four basic tastes
c. Pathways; Facial and Glossopharyngeal nerves in temporal and parietal lobes
4. Smell sensation: Chemoreceptors in the upper nasal cavities detect volatile (vaporized)
chemicals
a. Pathways: Olfactory nerves to olfactory bulbs connected to olfactory areas in the temporal
lobe
b. Smell and taste sensations are synergistic.

concern:
5460 4540
3999 6001
2000 8000
7000 3000
Assume the first row represents the first area of concern, such as “security”, the second row
could represent “education”, etc.
The first column could represent the first presidential candidate, John Brown, and the second
column could be for Jim Smith. The particular national concerns and the names of the candidates
as well as the votes will come from the keyboard. Do not hardcode any of the data for the arrays.
The arrays will be empty to begin with. The data must come from the keyboard. Be sure your
keyboard prompts are meaningful and clear to any user. You MUST NOT use any global
variables.
The output of your program will be the following:
Display the name of the national concern, the candidate and the percentage of 10000 each
candidate received in a nicely formatted table. You will need to use the io manipulators.
Display the name of the candidate that won the debate (highest total of all votes).

3.) epistasis
4.) codominance
5.) overdominance
Solution
2. Pleiotropy.
Some genes influence not only the triats generally associated with them but also many other
triats. The multiple effect of a gene is called pleiotropy and gene having multiple phenotypic
effects is called pleiotropic gene.
Pleiotropic genes may not have equal influecne on all triats they control and these genes may
cause a very evident expression of its specific triat (major effect) and less evident effects of its
other triat (secondsry effect).

d)a wild guess Dr. Neil Shubin, a paleontologist discovered one of the most famous
sarcopterygian fish fossils, Tiktaalik, a fish that has several tetrapod characteristics. In
determining where to hunt for this fossil, he knew that he was looking for rock from the
Devonian period that would have been near the equator 375 million years ago. He also knew
about plate tectonics and that the continents have shifted since that time. He concluded that one
of the places to hunt for this fossil was the Canadian Arctic, and indeed, that\'s where he found
this fascinating fossil. This form of reasoning, knowing where to hunt for this fossil, is known as
.
Solution
Answer;
\"Dr. Neil Shubin............................................This form of reasoning, knowing wheretp hunt for
ths fossil, is known as deductive reasoning.
Explanation:
Deductive reasoning is a valid reasoning process (a top to down logic) for making deductive
inference which is largely based on theory) as opposed to inductive inference (which is largely
based on observations). The logical process of detuctive reasoning starts from a general
statement (as in the present case) and examines the possibilities to reach a specific and logical
conclusion (as in the given case, possible place to hunt for the fossil of interest is determined
with the help of available knowledge and data). Thus with deductive reasoning process, the
paleontologist could build a theory and based on it he could make a prediction of its
consequences. In such a case, if the predicted theory is correct, the observations are also correct..

JAVAWrite a program that takes a command-line argument representin.pdf
- 1. JAVA Write a program that takes a command-line argument representing a text file name. The program should read the given text file and print two lists, each in ascending order. One list should be the words that exist only once in the text file. The other list should be the words that appear more than once. Ignore the case of the words when determining whether a word has appeared more than once. Your program may ignore punctuation. Solution //CountOccurrenceOfWords.java import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.IOException; import java.util.Map; import java.util.Set; import java.util.TreeMap; import java.util.ArrayList; import java.util.*; public class CountOccurrenceOfWords { public static void main(String[] file) throws FileNotFoundException, IOException { if (file.length == 0) { System.out.println("Usage: java CountOccurrenceOfWords targetfile"); System.exit(0); } BufferedReader br = null; br = new BufferedReader(new FileReader(file[0])); String text = null; TreeMap treemap = new TreeMap(); try
