Install Java 7

Xubuntu and Ubuntu both have OpenJDK pre-installed but I want Sun Java 7 for work purpose…

While there are so many ways to do it, I installed it using the PPA.

1) Remove the OpenJDK (optional – I like to remove stuff I don’t need)

Fire up the Terminal:

sudo apt-get purge openjdk*

2) Add the ppa

sudo add-apt-repository ppa:webupd8team/java

3) sudo apt-get update

Update apt-get with the new PPA

4) Install Java 7

sudo apt-get install oracle-java7-installer

Accept whatever and get a cup of coffee

5) Doublecheck my Java version
java -version
