Ubuntu Linux: Install Eclipse Java Integrated Development Environment

Q. How do I install Eclipse integrated development environment and write first program under Ubuntu Linux Eclipse IDE?

A. Eclipse is free and open source integrated development environment (IDE) software. You need to install Java JDK and JRE before installing Eclipse.

Install Sun JDK and JRE

Open terminal and type the following commands to install Sun Java JDK and JRE:
$ sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk
$ sudo vi /etc/jvm

Add following line at the top:
Set up environment:
$ echo 'export JAVA_HOME=/usr/lib/jvm/java-6-sun' >> ~/.bash_profile
$ echo 'export PATH=$PATH:$JAVA_HOME/bin' >> ~/.bash_profile
$ . ~/.bash_profile

Make sure you see correct JAVA version:
$ java -version
Sample output:

java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Server VM (build 10.0-b22, mixed mode)

Install Eclipse

Type the following command to install extensible Tool Platform, Java IDE, Java Development Tools plug-ins for Eclipse:
$ sudo apt-get install eclipse eclipse-jdt

How do I start eclipse?

Click on Applications > Programming > Eclipse

$ eclipse &

    I’ve always use the following to change default java versions:

    update-java-alternatives –list

    sudo update-java-alternatives –set

    1) May I know what is this for :
    $ sudo vi /etc/jvm
    Add following line at the top:

    I don’t have the jvm file under /etc/.
    2) After starting my ecilipse, I tried to create a class, but all contents below the question “Which method stub Would you like to create”in the graphic dialog is gone. I can’t select one method stub.
    3) After setting the PATH variable, I can start eclipse from anywhere, but if I click on the eclipse.exe on the file browser, an error message will show reading “Can’t find Java Virtual Machine…..”
    My eclipse is v 3.4.2 Ganymede
    Java jdk is jdk1.6.0_13

    Your help is much appreciated!

    I have followed most of your suggestions.
    I have Eclipse 3.5.2 installed as myself on Ubantou linkx 2.6.32-40
    I don’t have a ~/.bash_profile but put that in ~/.profile
    I don’t seem to have a Java profile. How do I enable that?
