T.Y.B.S.CS Advance Java Practicals Sem 5 Mumbai University
This document contains source code from multiple Java practical assignments involving Swing controls and database connectivity using JDBC. It includes source code for creating GUI elements like buttons, menus, scrollbars etc. using Swing controls. It also includes source code examples for performing database operations like creating tables, inserting data, and displaying data from tables using JDBC. The output of each practical is also displayed.
Easy Button
This document contains code for a Java GUI application called EasyGUI that allows users to generate automation results for order processing. It contains classes like EasyGUI, EasyButton, and BatchEngine that create a GUI, handle button clicks, and execute automation batches. When the submit button is clicked, it validates the order ID, runs batches to get conversation IDs, account numbers, and CSIXML files, and displays the results. It uses GridBagLayout to arrange components on the main panel and stores selection values in variables like orderID and accountNumber to pass to batch processing methods.
JJUG CCC 2011 Spring
The document provides an overview of Groovy and Java code examples for performing common tasks like printing "Hello World", reading files, making web requests, using strings, importing packages, and using Swing/SwingBuilder for GUIs. It also shows examples of using Groovy with Java libraries for Excel files, Ant, and JSON. Additional sections cover parallel processing with GPars, contract programming with GContracts, method chaining, Grails basics, and Gaelyk controllers and views.
Hibernate Import.Sql I18n
The document discusses three methods for importing SQL scripts using Hibernate:
1. Specify the import file in hibernate.cfg.xml using the classpath location
2. Directly specify the file path to import.sql
3. Implement a listener to convert the SQL file to the proper encoding on application startup

TextSearch
This Java code implements a basic text search feature by:
1) Creating a JComboBox and JTextField to allow the user to enter search text and see results.
2) Adding a key listener to the text field to detect key presses and retrieve search results from an Oracle database on key release.
3) Constructing a SQL query with a LIKE clause to find database records where a field matches the entered text, and adding any results to the dropdown.
Selenium Webdriver with data driven framework
This document describes a Selenium WebDriver data driven framework. It uses external files to store test data and object identifiers to make the framework more flexible and maintainable. The framework includes Java classes for reading test data from Excel files, retrieving object identifiers from property files, and implementing common test functions. Tests are implemented as Java classes that utilize the framework classes to login to a test application, retrieve test data, and verify application behavior.

201913046 wahyu septiansyah network programing
The document describes a network programming report on a Java chat application. It includes the code for a Server class that implements a threaded server to handle multiple client connections simultaneously. The server opens a port to listen for clients and spins up a new thread for each accepted connection. It then reads and writes data between the server and client over buffered input/output streams. The report notes issues with messages from one client not being visible to others and connection errors that can occur between the client and server.
A topology of memory leaks on the JVM
While most bugs reveal their cause within their stack trace, Java’s OutOfMemoryError is less talkative and therefore regarded as being difficult to debug by a majority of developers. With the right techniques and tools, memory leaks in Java programs can however be tackled like any other programming error. This talks discusses how a JVM stores data, categorizes different types of memory leaks that can occur in a Java program and presents techniques for fixing such errors. Furthermore, we will have a closer look at lambda expressions and their considerable potential of introducing memory leaks when they are used incautiously.

The document describes a Java program that creates a graphical user interface (GUI) calculator application. It defines variables to store numeric values and operations, initializes GUI components like buttons and text fields, and includes event handler methods for each button that perform number entry, arithmetic operations, and result display when the equals button is pressed. The main method creates an instance of the calculator class and makes it visible, launching the application.
XTW_Import
The document contains code for a C# program that merges employee wage and tip data from multiple text files into a single output file. It reads configuration settings from an XML file to determine the input and output file paths. It then reads the input files, merges the data based on employee identifiers, handles null values, and writes the results to the output file. It also writes log information to another output file. The key steps are: 1) reading the configuration, 2) reading and parsing the input files, 3) merging and formatting the data, and 4) writing the merged data and log to output files.
DCN Practical
This document contains source code for several Java programs that demonstrate concepts related to networking and URLs. The programs cover topics like retrieving a URL, getting URL information, working with InetAddress, demonstrating parts of a URL, and connectionless and connection-oriented communication between a server and client using UDP and TCP sockets. The code examples are accompanied by expected output.

The document discusses Java serialization and exceptions. It provides examples of implementing serialization by having a class implement the Serializable interface, which allows object instances to be written to and read from files. It also discusses exception handling using try-catch blocks and the finally clause, and how exceptions can be declared to be thrown from a method using the throws clause.

Balancing ANY chemical equation is done exactly t.pdf
Balancing ANY chemical equation is done exactly the same. Easiest way is to start
with a primary element such as Carbon, then just work your way back and forth between
products and reactants until everything is balanced. Be sure to check your equation once you\'re
done to make sure everything is balanced completely. Types of Chemical reactions: 1.)
Combustion: A combustion reaction is when oxygen combines with another compound to form
water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An
example of this kind of reaction is the burning of propane: C3H8 + 5O2 --> 3CO2 + 4H2O
*Hint: Combustion reactions always have O2 in the reactants and CO2 and H2O somewhere in
the products. 2.) Synthesis: A synthesis reaction is when two or more simple compounds
combine to form a more complicated one. These reactions come in the general form of: A + B --
-> AB One example of a synthesis reaction is the combination of iron and sulfur to form iron
(II) sulfide: 8 Fe + S8 ---> 8 FeS 3.) Decomposition: A decomposition reaction is the opposite
of a synthesis reaction - a complex molecule breaks down to make simpler ones. These reactions
come in the general form: AB ---> A + B One example of a decomposition reaction is the
electrolysis of water to make oxygen and hydrogen gas: 2 H2O ---> 2 H2 + O2 4.) Single
displacement: This is when one element trades places with another element in a compound.
These reactions come in the general form of: A + BC ---> AC + B One example of a single
displacement reaction is when magnesium replaces hydrogen in water to make magnesium
hydroxide and hydrogen gas: Mg + 2 H2O ---> Mg(OH)2 + H2 5) Double displacement: This is
when the anions and cations of two different molecules switch places, forming two entirely
different compounds. These reactions are in the general form: AB + CD ---> AD + CB One
example of a double displacement reaction is the reaction of lead (II) nitrate with potassium
iodide to form lead (II) iodide and potassium nitrate: Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3 6)
Acid-base: This is a special kind of double displacement reaction that takes place when an acid
and base react with each other. The H+ ion in the acid reacts with the OH- ion in the base,
causing the formation of water. Generally, the product of this reaction is some ionic salt and
water: HA + BOH ---> H2O + BA One example of an acid-base reaction is the reaction of
hydrobromic acid (HBr) with sodium hydroxide: HBr + NaOH ---> NaBr + H2O *Hint: An acid
plus a base always produces a salt and H2O as a product.

The document describes a network programming report on a Java chat application. It includes the code for a Server class that implements a threaded server to handle multiple client connections simultaneously. The server opens a port to listen for clients and spins up a new thread for each accepted connection. It then reads and writes data between the server and client over buffered input/output streams. The report notes issues with messages from one client not being visible to others and connection errors that can occur between the client and server.
A topology of memory leaks on the JVM
While most bugs reveal their cause within their stack trace, Java’s OutOfMemoryError is less talkative and therefore regarded as being difficult to debug by a majority of developers. With the right techniques and tools, memory leaks in Java programs can however be tackled like any other programming error. This talks discusses how a JVM stores data, categorizes different types of memory leaks that can occur in a Java program and presents techniques for fixing such errors. Furthermore, we will have a closer look at lambda expressions and their considerable potential of introducing memory leaks when they are used incautiously.

The document describes a Java program that creates a graphical user interface (GUI) calculator application. It defines variables to store numeric values and operations, initializes GUI components like buttons and text fields, and includes event handler methods for each button that perform number entry, arithmetic operations, and result display when the equals button is pressed. The main method creates an instance of the calculator class and makes it visible, launching the application.
XTW_Import
The document contains code for a C# program that merges employee wage and tip data from multiple text files into a single output file. It reads configuration settings from an XML file to determine the input and output file paths. It then reads the input files, merges the data based on employee identifiers, handles null values, and writes the results to the output file. It also writes log information to another output file. The key steps are: 1) reading the configuration, 2) reading and parsing the input files, 3) merging and formatting the data, and 4) writing the merged data and log to output files.
DCN Practical
This document contains source code for several Java programs that demonstrate concepts related to networking and URLs. The programs cover topics like retrieving a URL, getting URL information, working with InetAddress, demonstrating parts of a URL, and connectionless and connection-oriented communication between a server and client using UDP and TCP sockets. The code examples are accompanied by expected output.
Oop lecture9 12
The document discusses Java serialization and exceptions. It provides examples of implementing serialization by having a class implement the Serializable interface, which allows object instances to be written to and read from files. It also discusses exception handling using try-catch blocks and the finally clause, and how exceptions can be declared to be thrown from a method using the throws clause.

Balancing ANY chemical equation is done exactly t.pdf
Balancing ANY chemical equation is done exactly the same. Easiest way is to start
with a primary element such as Carbon, then just work your way back and forth between
products and reactants until everything is balanced. Be sure to check your equation once you\'re
done to make sure everything is balanced completely. Types of Chemical reactions: 1.)
Combustion: A combustion reaction is when oxygen combines with another compound to form
water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An
example of this kind of reaction is the burning of propane: C3H8 + 5O2 --> 3CO2 + 4H2O
*Hint: Combustion reactions always have O2 in the reactants and CO2 and H2O somewhere in
the products. 2.) Synthesis: A synthesis reaction is when two or more simple compounds
combine to form a more complicated one. These reactions come in the general form of: A + B --
-> AB One example of a synthesis reaction is the combination of iron and sulfur to form iron
(II) sulfide: 8 Fe + S8 ---> 8 FeS 3.) Decomposition: A decomposition reaction is the opposite
of a synthesis reaction - a complex molecule breaks down to make simpler ones. These reactions
come in the general form: AB ---> A + B One example of a decomposition reaction is the
electrolysis of water to make oxygen and hydrogen gas: 2 H2O ---> 2 H2 + O2 4.) Single
displacement: This is when one element trades places with another element in a compound.
These reactions come in the general form of: A + BC ---> AC + B One example of a single
displacement reaction is when magnesium replaces hydrogen in water to make magnesium
hydroxide and hydrogen gas: Mg + 2 H2O ---> Mg(OH)2 + H2 5) Double displacement: This is
when the anions and cations of two different molecules switch places, forming two entirely
different compounds. These reactions are in the general form: AB + CD ---> AD + CB One
example of a double displacement reaction is the reaction of lead (II) nitrate with potassium
iodide to form lead (II) iodide and potassium nitrate: Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3 6)
Acid-base: This is a special kind of double displacement reaction that takes place when an acid
and base react with each other. The H+ ion in the acid reacts with the OH- ion in the base,
causing the formation of water. Generally, the product of this reaction is some ionic salt and
water: HA + BOH ---> H2O + BA One example of an acid-base reaction is the reaction of
hydrobromic acid (HBr) with sodium hydroxide: HBr + NaOH ---> NaBr + H2O *Hint: An acid
plus a base always produces a salt and H2O as a product.

The compounds with low oxidation states (O.S.) be.pdf
The oxidation states of p-block main group elements like groups 13, 14, 15 and 16 become more stable at lower oxidation states further down the column. For group 14 elements C, Si, and Ge, the +4 oxidation state is most stable while the +2 state requires kinetic stabilization. For Sn, both +2 and +4 states are important but +4 is more common, and for Pb, the +2 state is most stable due to the inert pair effect caused by relativistic contraction of the s orbital. For transition metals, higher oxidation states also become less favorable down the column as ionization energies increase.

The fact that a molecule vibrates does not in its.pdf
The fact that a molecule vibrates does not in itself insure that the molecule will
exhibit an IR spectrum. For a particular vibrational mode to absorb infrared radiation, the
vibrational motion associated with that mode must produce a change in the dipole moment of the
molecule. HCl, for example, with a center of positive charge at the H atom and a center of
negative charge at the Cl atom, has a dipole moment. The magnitude of the dipole moment
changes as the HCl bond stretches, so this vibration absorbs IR radiation. We say that the
vibration is IR active. The N2 molecule, on the other hand, has no dipole moment. Further,
stretching the N-N bond does not produce a change in dipole moment, so the vibration is infrared
inactive (i.e., cannot directly absorb IR radiation). It is important to realize that there are many
molecules that, although possessing no permanent dipole moment, still undergo vibrations that
cause changes in the value of the dipole moment from 0 to some non-zero value. An example is
CO2, which has no permanent dipole moment because the individual bond dipoles exactly
cancel. However, when CO2 undergoes a bending vibration, its dipole moment changes from
zero to some non-zero value. This vibration produces a change in dipole moment and is IR
active. These vibrational modes are responsible for the \"greenhouse\" effect in which heat
radiated from the earth is absorbed (trapped) by CO2 molecules in the atmosphere. The arrows
indicate the directions of motion. Vibrations labeled A and B represent the stretching of the
chemical bonds, one in a symmetric (A) fashion, in which both C=O bonds lengthen and contract
together (in-phase), and the other in an asymmetric (B) fashion, in which one bond shortens
while the other lengthens. The asymmetric stretch (B) is infrared active because there is a change
in the molecular dipole moment during this vibration.

The compounds of interest are Na2S and H2SO4. Th.pdf
The compounds of interest are Na2S and H2SO4. The molecular equation then is:
Na2S + H2SO4 ---> Na2SO4 + H2S. Just exchange one anion for the other. Now, we need to
know a little bit about the properties of these compounds. Almost all sodium salts are soluble, so
both Na2S and Na2SO4 are fully dissociated: 2 Na+ + S2- + 2 H+ + SO42- ---> 2 Na+ + SO42-
+ H2S. Crossing out terms that appear on both sides, we obtain the net ionic equation: 2 H+ +
S2- ----> H2S. Conveniently, H2S is a gas, and escapes from solution. Thus, it selectively
removes H+ and S2- ions from the equilibrium, driving the reaction to completion (favoring
Na2SO4)
