This package provides Oracle Java JDK 7 (which includes Java JDK, JRE and the Java browser plugin). However, you can't only install Oracle JRE - the PPA only provides the full Oracle JDK7 package.
To add PPA and install the latest Oracle Java 7 in Ubuntu (supports Ubuntu 13.10, 13.04, 12.10, 12.04 and 10.04) or Linux Mint, use the commands below:
sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java7-installer
After the installation finishes, if you wish to see if it was successful, you can run the following command:
It should return something like this:
java version "1.7.0_51" Java(TM) SE Runtime Environment (build 1.7.0_51-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
The package installs all the Java binaries, so you can also try "javac -version" which should return "javac 1.7.0_51" and so on (the "_51" part of the version can be different because they are constantly updating the PPA with the latest Oracle Java 7 version). The current JDK version in the PPA is Oracle Java 7 Update 51 (7u51).
If for some reason, the Java version in use is not 1.7.0, you can try to run the following command:
sudo update-java-alternatives -s java-7-oracle
Update: the installer now requires you accept the Oracle license before the installation begins. This is only required once. If for some reason you need the installation to be automated, you can run the following command to automatically accept the Oracle license:
echo oracle-java7-installer shared/accepted-oracle-license-v1-1 select true | sudo /usr/bin/debconf-set-selections
Setting Java environment variables
To automatically set up the Java 7 environment variables, you can install the following package:
sudo apt-get install oracle-java7-set-default
If you've already installed oracle-java6-set-default or oracle-java8-set-default, they will be automatically removed when installing oracle-java7-set-default (and the environment variables will be set for Oracle Java 7 instead).
Removing Oracle Java 7
If you don't want to use Oracle Java (JDK) 7 anymore on your Ubuntu / Linux Mint computer and want to go back to OpenJDK, all you have to do is remove the Oracle JDK7 Installer and the previous Java (OpenJDK, etc.) version will be used:
sudo apt-get remove oracle-java7-installer
