1. The document provides instructions for installing the Java Development Kit (JDK) and configuring Eclipse to set up a Java development environment. 2. It describes downloading and installing the JDK, setting environment variables, and verifying the installation. 3. It also outlines extracting and opening Eclipse, creating a Java project with source folders and classes, and how to run and debug Java programs from within Eclipse.

1. INSTALLATION
JDK Installation
1. Download JDK 1.7 or above version from the following link:
http://www.oracle.com/technetwork/java/javase/downloads/index.html. Before
downloading check System type (32-bit / 64-bit) Operating System.
Note: Mac user can refer http://www.cs.princeton.edu/courses/archive/spr04/cos126/hello/mac.html
for more details.
2. Install the downloaded version into the system.

2. 2.1. Accept the License.
2.2. Next set the location where you like to install Java. It is always recommended to
install in default path recommended by sun (D:Program FilesJavajdk1.7.0_25).

3. 3. Set JAVA_HOME, PATH, CLASSPATH as follows:
Desktop  Right click on “Computer”  Properties  Advanced system settings
Environment Variables  Either in User variables or System variables section:
JAVA_HOME= D:Program FilesJavajdk1.7.0_25
PATH= .; D:Program FilesJavajdk1.7.0_25bin
CLASSPATH=.; D:Program FilesJavajdk1.7.0_25jrelibrt.jar
4. To verify whether you installed it and set the PATH and CLASSPATH, open new the
CMD prompt and test whether JAVAC or JAVA are working or not.

4. ECLIPSE CONFIGURATION
1. First download the appropriate version of Eclipse IDE from the following
link: http://www.eclipse.org/downloads/
2. Extract the files in that archive file into another
3. After extracting the files, open the eclipse IDE by clicking on the eclipse.exe
file.
4. While opening the IDE it will prompt you to select the workspace
(Workspace is the place where we create or store the class files and java
files). Specify the path where you want to create the workspace.
5. To create a new Java project by following steps…
6. After selecting the project a dialog will be appearing on the screen. Select
the “Java Project”.

5. Click on “Next”  Project Name: “Java Examples”  Finish

6. Creating Source Folder
For my convenience I would like to create separate source folder for every chapter.
Right Click on Project (Java Examples)  New  Source Folder  Give Name (Introduction)
 Finish.
Creating a Class in Eclipse: -
1. Right Click on the Source folder, Select “New” and Select “Class”

7. 2. Create the class and give the name to it and click on finish.

8. Customizing the templates in Eclipse for easier use of IDE: -
1. Select the Window button in eclipse and select ‘Preferences’.
Then following dialog box will be opened.

9. 2. Expand ‘java’ list in the left pane and Expand sub element-Editor
and select the Templates button in it.

10. 3. To configure our own templates follow the following screen shots.
First select the “New…” button.
4. After creating this we can use “sop”+ctrl+space bar in place of
System.out.println();. It will make the developer work much
simpler…..
