Uninstall JAVA on LINUX Systems

RPM Package:
If the Java Development Kit was installed using RPM we can check it using ‘rpm -qa | grep jdk’. If this command shows any JDK version then you can easily remove the rpm package using ‘rpm –erase [javapackagename]‘
Self Extracting File:
If the JDK was installed using self extraction zip file then we can directly remove the JDK folder using ‘rm -rf ‘
