Pre-Install Procedures:
# apt-get purge openjdk-\*
# mkdir -p /usr/local/java
This purges the open Java from your system.
Install Procedures:
Download Java and JDK from the Java website
Unpack the files into the /usr/local/java folder
Post-Install Procedures:
The following edits your profile:
# echo "JAVA_HOME=/usr/local/java/jdk1.7.0_21" >> /etc/profile
# echo "PATH=$PATH:$HOME/bin:$JAVA_HOME/bin" >> /etc/profile
# echo "JRE_HOME=/usr/local/java/jre1.7.0_21" >> /etc/profile
# echo "PATH=$PATH:$HOME/bin:$JRE_HOME/bin" >> /etc/profile
# echo "export JAVA_HOME" >> /etc/profile
# echo "export JRE_HOME" >> /etc/profile
# echo "export PATH" >> /etc/profile
This Informs sytem where Java is
# update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jre1.7.0_21/bin/java" 1
# update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.7.0_21/bin/javac" 1
# update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jre1.7.0_21/bin/javaws" 1
Updates Java as default Java
# update-alternatives --set java /usr/local/java/jre1.7.0_21/bin/java
# update-alternatives --set javac /usr/local/java/jdk1.7.0_21/bin/javac
# update-alternatives --set javaws /usr/local/java/jre1.7.0_21/bin/javaws
Optional Java Browser Plugins:

You should now have Java on your system.
You can test by typing java -version at the command line.
If you are lazy, in a hurry or just want to do it the easy way:

This package does all the above.
