How-to Install Oracle Java JDK 7 on Elementary OS Linux 32-64bit Step-by-Step Easy Guide

1. Download Oracle-Sun Java SE JDK 7 for Linux:

   Oracle JDK 7 i586/x64 tar.gz

   On the Java SE JDK Section Select the tar.gz Linux Release.

2. Open Terminal Window
   (Press “Enter” to Execute Commands)

   Ctrl+Alt+t

   

3. Double-Click on the Jdk7 tar.gz Archive

   Or from Shell:

   tar xvzf ~/Downloads/jdk-7*.tar.gz -C /tmp/

   

   Then Extract it Into the /tmp Folder.

4. Relocate JDK 7

   sudo su

   If Got “User is Not in Sudoers file” then Look: Solution

   if [ ! -d "/usr/lib/jvm" ]; then mkdir /usr/lib/jvm; fi

   The above command is used to create a jvm directory if not already there.

   chown -R root:root /tmp/jdk1.7*

   Reiterate the Execution Permission over the Java binaries

   chmod -R +x /tmp/jdk1.7*/bin

   Finally Shift the Java content with

   mv /tmp/jdk1.7* /usr/lib/jvm/

5. Installing Oracle Java JDK 7

   update-alternatives --install \
   /usr/bin/java java /usr/lib/jvm/jdk1.7*/bin/java 1065

   update-alternatives --install \
   /usr/bin/javac javac /usr/lib/jvm/jdk1.7*/bin/javac 1065

   update-alternatives --install \
   /usr/bin/jar jar /usr/lib/jvm/jdk1.7*/bin/jar 1065

   update-alternatives --install \
   /usr/bin/javaws javaws /usr/lib/jvm/jdk1.7*/bin/javaws 1065

   Checking or Setting the System Java Version in Use with

   update-alternatives --config java

   To Switch of Java Version Just Enter the Reference Number on First Column. :)
