If you have already installed Ubuntu 12.04 you probably have realized that Sun java(oracle java) does not come prepacked with Ubuntu like it used to be , instead OpenJDK comes with it. Here is how you can install Oracle java on Ubuntu 12.04 manually.

Download jdk-6u32-linux-x64.bin from this link. If you have used 32-bit Ubuntu installation, download jdk-6u32-linux-x32.bin instead.
To make the downloaded bin file executable use the following command
1. ```
    chmod +x jdk-6u32-linux-x64.bin  
```
To extract the bin file use the following command
1. ```
    ./jdk-6u32-linux-x64.bin  
```
Using the following command create a folder called "jvm" inside /usr/lib if it is not already existing
1. ```
    sudo mkdir /usr/lib/jvm  
```
Move the extracted folder into the newly created jvm folder
1. ```
    sudo mv jdk1.6.0_32 /usr/lib/jvm/  
```

To install the Java source use following commands

    sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_32/bin/javac 1  
    sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_32/bin/java 1  
    sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_32/bin/javaws 1

To make this default java

    sudo update-alternatives --config javac  
    sudo update-alternatives --config java  
    sudo update-alternatives --config javaws

To make symlinks point to the new Java location use the following command
1. ```
    ls -la /etc/alternatives/java*  
```
To verify Java has installed correctly use this command
1. ```
java -version  
```
