Typicly:
$ cd ~/Downloads
Step 4: Exctract images to the installation folder
$ sudo tar xvf jdk-7u79-linux-x64.tar.gz -C /usr/lib/jvm/ $ sudo tar xvf jre-7u79-linux-x64.tar.gz -C /usr/lib/jvm/
Step 5: Change to the installation folder.
$ cd /usr/lib/jvm
Step 6: Make the downloaded binaries executable.
$ sudo chmod a+x jdk-6u45-linux-x64.bin $ sudo chmod a+x jre-6u45-linux-x64.bin
Step 7: Check your extracted folder names.
$ ls -l
Response: jdk1.7.0_79, jre1.7.0_79
Step 8: Inform Ubuntu where your Java installation is located.
$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jre1.7.0_79/bin/java 1 $ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.7.0_79/bin/javac 1
Step 9: Inform Ubuntu that this is your default Java installation.
$ sudo update-alternatives --set java /usr/lib/jvm/jre1.7.0_79/bin/java $ sudo update-alternatives --set javac /usr/lib/jvm/jdk1.7.0_79/bin/javac
Step 10: Update your system-wide PATH.
