Here i'm going to show, How to install JDK 8(latest) in Linux 14 from tar file

1. Download JDK8 tar file from java website

2. Extract downloaded tar file in terminal with following command

tar -xzf filename

3. After 2nd step move extracted JDK folder to /usr/local, to do this we need to execute following as superuser(SU)

sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/jdk1.8.0_45/bin/javaws" 1

If JPS is not working( If JPS present in jdk/bin directory) run following command

sudo update-alternatives --install "/usr/bin/jps" "jps" "/usr/local/jdk1.8.0_45/bin/jps" 1

5. At last, but not least we need to update JAVA_HOME location in .bashrc file
