JRE_HOME=$JAVA_HOME/jre
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH

Add the new version of java, javac and javaws as an system alternative and give it priority 1.

sudo update-alternatives –install “/usr/bin/java” “java” “/usr/lib/java/[jdk]/bin/java” 1
sudo update-alternatives –install “/usr/bin/javac” “javac” “/usr/lib/java/[jdk]/bin/javac” 1
sudo update-alternatives –install “/usr/bin/javaws” “javaws” “/usr/lib/java/[jdk]/bin/javaws” 1

To config multiple versions.

sudo update-alternatives --config java
