Install Sun (Oracle) Java on Ubuntu without using PPAs

Install JDK on Ubuntu manually without depending on PPAs –

1. Select the required package from here – http://www.oracle.com/technetwork/java/javase/downloads/index.html. Download the jdk-[version].bin file from the downloads page.
2. Make the downloaded file runnable; Eg – sudo chmod +x jdk-6u32-linux-x64.bin
3. Run this file; Eg- sudo ./jdk-6u32-linux-x64.bin
4. Move the newly created folder to /usr/lib/jvm/. Eg – sudo mv jdk1.6.0_32 /usr/lib/jvm/ (Optionally change the user of this folder to yourselves)
5. Add the newly added jdk to known java command option –

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

6. Choose the new java, javac and javaws by running commands-

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

Run java -version to verify installation. Cheers!
