>>So, first of all, check the vendor of the JDK you have installed on your system, whether it is Oracle JDK or Openjdk. For that execute the following command in the terminal:


$ java -version


>>If you have Oracle JDK installed then you will get the following result:

	anshuman@developer:~$ java -version
	java version "1.8.0_112"
	Java(TM) SE Runtime Environment (build 1.8.0_112-b15)
	Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)
	Else if you have Openjdk installed then you will get the following result:

	anshuman@developer:~$ java -version
	java version "1.7.0_91"
	OpenJDK Runtime Environment (amzn-2.6.2.2.63.amzn1-x86_64 u91-b00)
	OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)
	Now follow the instructions below according to the JDK you have installed.

>>UNINSTALL ORACLE JDK
	Remove The Link
	First of all remove the alternatives by executing the following commands:


$ sudo update-alternatives --remove "java" "/usr/lib/jvm/jdk[version]/bin/java"
$ sudo update-alternatives --remove "javac" "/usr/lib/jvm/jdk[version]/bin/javac"
$ sudo update-alternatives --remove "javaws" "/usr/lib/jvm/jdk[version]/jre/bin/javaws"


>>Note: Replace the [version] with any version number that’s contained in jdk folder’s name. For example: jdk1.8.0_131.

	Remove The Package
	After removing link, remove the package inside /usr/lib/jvm/jdk[version] by executing following command:


$ sudo rm -r /usr/lib/jvm/jdk[version]


>>UNINSTALL OPENJDK
	If you want to remove Openjdk only, execute the following command on terminal:


$ sudo apt-get remove openjdk*


>>If you want to remove Openjdk along with dependencies, execute the following command on terminal:


$ sudo apt-get remove --auto-remove openjdk*


>>If you want to remove Openjdk and it’s configuration files, execute the following command on terminal:


$ sudo apt-get purge openjdk*


>>If you want to remove Openjdk along with dependencies and it’s configuration files, execute the following command on terminal:


$ sudo apt-get purge --auto-remove openjdk*
