Download the java here ;
Double-click the package and put it in / tmp or go to the shell and ...
$ tar xvzf ~/Downloads/jdk-8*.tar.gz -C /tmp/
At the command line, create a directory, if it does not exist and assign root as owner, assign execute permissions and move to /usr/lib/jvm/
$ sudo su
$ if [ ! -d "/usr/lib/jvm" ]; then mkdir /usr/lib/jvm; fi
$ chown -R root:root /tmp/jdk1.8*
$ chmod -R +x /tmp/jdk1.8*/bin
$ mv /tmp/jdk1.8* /usr/lib/jvm/
Install it
update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.8*/bin/java 1065
update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.8*/bin/javac 1065
update-alternatives --install /usr/bin/jar jar /usr/lib/jvm/jdk1.8*/bin/jar 1065
update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.8*/bin/javaws 1065
Check or Set the version of java that you have / want to use:
update-alternatives --config java
Set the environment variable (optional) by editing the file $HOME/.bashrc
by adding the line:
export JAVA_HOME=/usr/lib/jvm/jdk1.8[uX]
[uX] at the end of the above command is equivalent to the final digits of the version you installed.
Finally, test the installation:
java -version
