1. Download tar.gz installer file as below from oracle website :
jdk-8uversion-linux-x64.tar.gz (installer file)
2. Change to user as your wish. I have installed java here as ‘oracle’ user.
$ su – oracle
3. Copy the installer file where you want to install. Change ownership of the installer file if you download as different user:
$ chown oracle jdk-8u111-linux-x64.tar.gz (assigning ownership to oracle user)
4. Unpack the tarball and install the JDK.
$tar zxvf jdk-8uversion-linux-x64.tar.gz
The Java Development Kit files are installed in a directory called jdk1.8.0_version in the current directory.
