#### First verify the version of Java being used is not Sun Java 8 SDK
`java -version`
 
#### Get the Sun Java 8 SDK from Oracle
`wget --no-cookies --header "Cookie: gpw_e24=xxx; oraclelicense=accept-securebackup-cookie;" "http://download.oracle.com/otn-pub/java/jdk/8u73-b02/jdk-8u73-linux-x64.rpm"`
 
#### Install Sun Java 8
`sudo rpm -i jdk-8u73-linux-x64.rpm`
 
#### Check if the default java version is set to Sun Java 8 SDK
`java -version`
 
#### If not then lets create one more alternative for Sun Java 8 SDK
`sudo /usr/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.8.0_73/bin/java 20000`
 
#### Set the Sun Java 8 SDK as the default java
`sudo /usr/sbin/alternatives --set java /usr/java/jdk1.8.0_73/bin/java`
 
#### Verify if change in SDK was done
`java -version`

#### Setup JAVA_HOME
```
sudo vim /etc/profile
```

Add inside this file the following lines
```text
export JAVA_HOME="/usr/java/jdk1.8.0_73/"
export PATH=$JAVA_HOME/bin:$PATH
```

Then save it. Load the configuration immediately using

`source /etc/profile`

Then finally, check if it works

`echo $JAVA_HOME`
