I’ve made a decision to learn Java again to prepare myself before graduated. Flash back my memory about this programming language (just the basic).

But this time I wanna learn on my ubuntu machine. And this is my a little note, when I was installing Java+Netbeans on Ubuntu.

1. Install the latest JDK

sudo apt-get install sun-java6-jdk

To verify that the installation was successful, execute

java – version

You may get the result like this:

java version “1.6.0_03″
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)

To make sure that you use Java from Sun, execute

sudo update-alternatives –config java

Set JAVA_HOME path by add this line at the bottom of file /etc/environment

JAVA_HOME=”/usr/lib/jvm/java-6-sun”

or just execute

export JAVA_HOME=”/usr/lib/jvm/java-6-sun”

And You may include some packages to install, like :

1. sun-java6-bin – Contains the binaries
2. sun-java6-demo – Contains demos and examples
3. sun-java6-doc – Contains the documentation
4. sun-java6-fonts – Contains the Lucida TrueType fonts from the JRE
5. sun-java6-jre – Contains the metapackage for the JRE
6. sun-java6-plugin – Contains the plug-in for Mozilla-based browsers
7. sun-java6-source – Contains source files for the JDK

2. Download the latest Netbeans with ‘All’ version (remember the file extension is *.sh), from this.

3. Install Netbeans (ex: netbeans-6.0.1-ml-linux.sh)

sh netbeans-6.0.1-ml-linux.sh

This will triger the netbeans installer and just follow the instructions to complete the installation process.
