sudo yum install java-1.8.0

if you need a java compiler and other developer tools:

sudo yum install java-1.8.0-openjdk-devel

Step-2: If you have multiple versions and one of those default , use the alternatives command as follows and enter the selection number as guided in the terminal.

sudo /usr/sbin/alternatives –config java
sudo /usr/sbin/alternatives –config javac
