Say I had a 2d array called answers[][]. The array is 2 columns, so 0 and 1 and about 60ish rows long. I need to write the whole Array to a file I create. And then close that file. Any idea how to do this using Java? Solution import java.io.BufferedWriter; import java.io.File; import java.io.FileWriter; import java.io.IOException; public class WriteFile { public static void main(String[] args) throws IOException { //lets array has elements inside int answers[][] = new int[60][2]; String fileName = \"records.txt\";// output file name File file = new File(fileName); FileWriter fw= new FileWriter(file); BufferedWriter bw = new BufferedWriter(fw); int i=0; while(i < 60){ // reading 60 rows bw.write(answers[i][0]+\" \"+answers[i][1]); // writing current column bw.newLine(); // writing new line i++; } bw.close(); fw.close(); } } .

A Java class that allows writing to files is Class FileWriter. This class is a part of java.io package and extends (inherits from) OutputStreamWriter class.
This class allows us to write character files conveniently. The reason I chose this class is because of the functionality provided by FileWriter class. It allows us to write to a new file, as well as append content to an existing file. Given a filename as a string parameter, it creates the file if it does not already exist. So, the user is not required to explicitly create a new file before writing to it using FileWriter class.
FileWriter class provides several constructors, which are as follows:
1) FileWriter(File file) - takes File object as a parameter, which corresponds to the file, the data is to be written to.
2) FileWriter(File file, boolean append) - takes two parameters: one is the File object to which data is to be written to, and second is a boolean parameter which indicates whether data is to be appended to the file
3) FileWriter(String filename) - takes a string parameter for the filename
4) FileWriter(String filename, Boolean append) - takes two parameters, one for the filename (string) and a Boolean value indicating whether data should be appended to the file or not
Pseudo code:
1. Create a string array and initialize elements of the array with given data
String[] dataArray = new String[4];
dataArray[0] = "1001 Jennifer Ward SUPPLIES 2140.20 BOOKS 5200.10 PAPER 455.23 NORTH Phone";
dataArray[1] = "1003 Athena Andrews SUPPLIES 5155.55 BOOKS 6300.50 PAPER 223.25 SOUTH Email";
dataArray[2] = "1005 Andy Smith SUPPLIES 6155.55 BOOKS 300.50 PAPER 55.55 SOUTH Email";
dataArray[3] = "1006 Robert Stearns SUPPLIES 7255.55 BOOKS 8300.50 PAPER 77.77 SOUTH Phone";
2. Create a File object and pass the filename
File file = new File(“data.txt”);
3. Check if file exits by that name, if it does not create a new file as follows:
file.createNewFile();
4. Create FileWriter object by passing the File object created above
5. In a for loop write each element of the array to the file:
for(int i=0; i<dataArray.length; i++){
writer.write(dataArray[i]); //write the line to file
writer.write("\n"); //write a newline to the file
}
6. Close the writer.
7. Catch any exceptions if thrown

file-transfer-using-tcp.pdf
The document describes a Java program for file transfer using TCP sockets. It includes algorithms for both a server and client. The server accepts connections, reads a file, and sends it to the client in byte chunks. The client receives the file contents and writes them to a new file. The program code shows how to create sockets, get input/output streams, read/write files and bytes, and close connections. It was tested by running the server and client programs which successfully transferred a file.
Unit No 5 Files and Database Connectivity.pptx
The document provides information about File classes and Input/Output streams in Java. It discusses the File class which represents file and directory pathnames and allows creating, deleting, and renaming files. It also describes InputStream and OutputStream classes used for reading bytes from and writing bytes to streams. Examples are given of using FileInputStream to read from a file and FileOutputStream to write to a file. The document also discusses RandomAccessFile for random access of files and JDBC for connecting to databases.
Chapter 6 Java IO File
The document discusses reading and writing text files in Java. It shows how to use the PrintWriter class to write data like names and scores to a text file. It then demonstrates using the Scanner class to read the data back from the file by parsing the strings and integers. The example writes two names and scores to a file, and then reads and prints out the same data.
ExtraFileIO.pptx
The document discusses file input and output in Java. It covers the File class, opening files for reading using a Scanner, handling exceptions, reading data line-by-line and tokenizing the lines. It also discusses opening files for writing using a PrintWriter and outputting data to files. The key topics are file I/O, exception handling, and using Scanners and PrintWriters to read from and write to files in Java.

java programming language
The attached A12.txt file which has 2 columns with the first column being the name of the
employee and the second column holding their salary. Read the data into a 2 dimensional array
of size 1,000 rows. Once the data is inside the 2-D array print out the unsorted contents to the
screen only of the rows that are currently in-use. Sort the data using selection sort from lowest
salary to highest salary ensuring the name continues to match up with the corresponding salary.
For only the rows that are currently in-use, print the sorted array to the screen and save the sorted
data to an output file named \"Sorted.txt\". Turn in A12.txt, .java file, and Sorted.txt all in 1 zip

Light travelling through the air (n - 1) strikes the surface of a diam.docx
Light travelling through the air (n = 1) strikes the surface of a diamond (n = 2.42) at a large angle of incidence. Which of the following describes the light ray as it enters the diamond?
a) the light bends toward the normal to the surface, and slows down
b) the light bends toward the normal to the surface, and speeds up
c) the light bends away from the normal to the surface, and slows down
d) the light bends away from the normal to the surface, and speeds up
e) the light ray does not enter the diamond, but totally reflects and stays in the air
Solution
When light is enter into rare medium to denser medium than light rays bends towards the normal.
Light slows as it travels through a substance and every substance has an index of refraction which defined as the ratio of the speed of light in vacuum to the speed of light in that substance. The index of refraction for diamond is 2.4 which means that light is 2.4 times slower in diamond .
Hence Option A is correct.
Hope it will help you. Please rate the answer.

file-transfer-using-tcp.pdf
The document describes a Java program for file transfer using TCP sockets. It includes algorithms for both a server and client. The server accepts connections, reads a file, and sends it to the client in byte chunks. The client receives the file contents and writes them to a new file. The program code shows how to create sockets, get input/output streams, read/write files and bytes, and close connections. It was tested by running the server and client programs which successfully transferred a file.
Unit No 5 Files and Database Connectivity.pptx
The document provides information about File classes and Input/Output streams in Java. It discusses the File class which represents file and directory pathnames and allows creating, deleting, and renaming files. It also describes InputStream and OutputStream classes used for reading bytes from and writing bytes to streams. Examples are given of using FileInputStream to read from a file and FileOutputStream to write to a file. The document also discusses RandomAccessFile for random access of files and JDBC for connecting to databases.
Chapter 6 Java IO File
The document discusses reading and writing text files in Java. It shows how to use the PrintWriter class to write data like names and scores to a text file. It then demonstrates using the Scanner class to read the data back from the file by parsing the strings and integers. The example writes two names and scores to a file, and then reads and prints out the same data.
ExtraFileIO.pptx
The document discusses file input and output in Java. It covers the File class, opening files for reading using a Scanner, handling exceptions, reading data line-by-line and tokenizing the lines. It also discusses opening files for writing using a PrintWriter and outputting data to files.

employee and the second column holding their salary. Read the data into a 2 dimensional array
of size 1,000 rows. Once the data is inside the 2-D array print out the unsorted contents to the
screen only of the rows that are currently in-use. Sort the data using selection sort from lowest
salary to highest salary ensuring the name continues to match up with the corresponding salary.
For only the rows that are currently in-use, print the sorted array to the screen and save the sorted
data to an output file named \"Sorted.txt\". Turn in A12.txt, .java file, and Sorted.txt all in 1 zip

Light travelling through the air (n - 1) strikes the surface of a diam.docx
Light travelling through the air (n = 1) strikes the surface of a diamond (n = 2.42) at a large angle of incidence. Which of the following describes the light ray as it enters the diamond?
a) the light bends toward the normal to the surface, and slows down
b) the light bends toward the normal to the surface, and speeds up
c) the light bends away from the normal to the surface, and slows down
d) the light bends away from the normal to the surface, and speeds up
e) the light ray does not enter the diamond, but totally reflects and stays in the air
Solution
When light is enter into rare medium to denser medium than light rays bends towards the normal.
Light slows as it travels through a substance and every substance has an index of refraction which defined as the ratio of the speed of light in vacuum to the speed of light in that substance. The index of refraction for diamond is 2.4 which means that light is 2.4 times slower in diamond .
Hence Option A is correct.
Hope it will help you. Please rate the answer.

Let-'s shift our focus a little and talk about Telehealth- Using to re.docx
Let\'s shift our focus a little and talk about Telehealth. Using to resources and APA citations: What is it and what are some different career opportunities for nurses using telehealth (e.g., nurse-run call centers for insurance companies). How is privacy maintained?
Solution
Telehealth Technologies -- Offering a wide array of new opportunities for nurses worldwide
The good news about telehealth is that not only can it be of great value to patients in remote locations, it can also help nurses in their everyday practice and provide them with an expanded set of career choices. Telehealth makes it possible to share medical skills, information, and know how; it can also provide nurses -- be they novices, experts, or somewhere in-between -- the opportunity to play an important role in the development, deployment, and utilization of telemedicine and telehealth applications in patient care.
Telehealth technologies allow clinicians to conduct remote physical assessment and consults, as well as capture and store patient information (with a store-and-forward software application) for further evaluation and sharing with a consulting physician or nurse practitioner.
Telehealth/Telemedicine/e-Health - What\'s Important to Know
There are six areas that are important to master in clinical telemedicine.
Resources
Nurses can educate themselves on these areas in several ways, including:

Let L(x1- x2- x3- x4- x5- x6- x7) - 2x3 + 3x4 + 8x6 + x7- Is L a linea.docx
Let L(x1; x2; x3; x4; x5; x6; x7) = 2x3 + 3x4 + 8x6 + x7: Is L a linear map?
If it is, find as many independent vectors in Ker(L) as you can.
Solution
L(x1; x2; x3; x4; x5; x6; x7) = 2x3 + 3x4 + 8x6 + x7
Since L satisfies scalar multipication and addition properties, it is a LINEAR map
rank of transformation matrix = 4
=>dimension of kernal = 7-4 = 3
=>maximum number of independent vectors in kernel = 3
=>these vectors are : (1 0 0 0 0 0 0), ( 0 1 0 0 0 0 0) , (0 0 0 0 1 0 0 )

Look at the energy curve for butane and oxygen combining to form CO2.docx
Solution
Answer
The reverse reaction cannot occur
Explanation
Reverse reaction is nonspontaneous: True statement because potential energy of CO2 + H2O is lower than Potential energy of Butane +O2
Butane and Oxygen have greater potential energy than CO2 + H2O : True statement
Ther forward spontaneous reaction occurs once the activation energy provided : true statement
The reverse reaction cannot occur : not correct because reverse reaction can be achieved in different path way.

List three factors that contribute to the severity of acid rock draina.docx
List three factors that contribute to the severity of acid rock drainage at Earth\'s surface, such as from legacy coal mining.
Solution
Acid rock drainage is formed by the natural oxidation of common sulphitde minerals when they are exposed to water & aIR
FACTORS THAT CONTRIBUTE TO THE SEVERITY OF ACID ROCK DRAINAGE (ARD)AT EARTH SURFACE ARE
Temperature: Pyrite oxidation occurs most quickly at a temperature around 30°C.
Microorganisms present: Some microorganisms are able to accelerate ARD production.
Amount of oxygen present: Sulphide minerals oxidize more quickly where there is more oxygen available. As a result, ARD formation rates are higher where the sulphides are exposed to air than where they are buried under soil or water
.Amount of water available: Cycles of wetting and drying accelerate ARD formation by dissolving and removing oxidation products, leaving a fresh mineral surface for oxidation. In addition, greater volumes of ARD are often produced in wetter areas where there is more water available for reaction.
Type of minerals present: Not all sulphide minerals are oxidized at the same rate, and neutralization by other minerals present may occur, which would slow the production of ARD.

List 6 reasons WHY we treat wastewater focused on the different types.docx
List 6 reasons “WHY” we treat wastewater focused on the different types of contaminants in municipal wastewater.
Solution
Due the fact that waste water is generated with different types contaminents which are composed of salts,ammonia,pathogenic material,pesticides,chemicals such as nitrates,posphorus etc.....................
Most conventional waste water plants are through rivers,lakes and streams all these plants have (National POllutant Discharges Elimination System) NPDES
Different types of pollutants are present in waste water are
1) BOD (Bio Chemical Oxygen Demand)
2) Ph value
3) Total suspended values
4) coliform bacteria
5) metals
6) Total dissolved solids
7) pesticides
8) Pharacetimals
The Different reasons why we treat waste water treatment focused on contaminents are
1) Clean water is critical to plants and animals that live in water and drink water This is important for fishing industries,animal lifes and plants
2) All the water that is diposed into lakes and rivers used in villages for drinking so we should treat the water for removing pollutants
3) Sewage or waste water can be recycled and used for any purpose of usage of water
4) As if we dont properly treat waste water it carries so many harmful bacteria and viruses which may cause danger to health as we play and stay with water for long time (example : oceans,rivers )
5) The chemicals and toxic acids present in water may cause various side effects to species (any species)
6) If water is not teated all the water is sent into oceans and rivers which pollute them and cause effect to aquatic and wild life
7) If the waste water is sent into lakes or ponds all the ground water in that area is polluted
So we should treate waste water depending on the contaminents present in water
