4. Relocate Java JDK 10.

   sudo su

   If Got “User is Not in Sudoers file” then see: How to Enable sudo
   Make a jvm Directory if Not already there with

   if [ ! -d "/usr/lib/jvm" ]; then mkdir /usr/lib/jvm; fi

   Set the root superUser as owner:

   sudo chown -R root:root /tmp/jdk-10*

   Reiterate the Execution Permission over the Java binaries:

   chmod -R +x /tmp/jdk-10*/bin

   Finally, Shift the Java contents with:

   mv /tmp/jdk-10* /usr/lib/jvm/

   You can directly Copy & Paste the Commands into Terminal..

   update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-10*/bin/java 1065

   update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk-10*/bin/javac 1065
