Installing

4. 4. Installing

   Then to Install Java JDK 10
   First, Make a jvm Directory if Not already there with:

   sudo su -c 'if [ ! -d "/usr/lib/jvm" ]; then mkdir /usr/lib/jvm; fi'

   If Got “User is Not in Sudoers file” then see: How to Enable sudo
   Set the root superUser as owner:

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

   Reiterate the Execution Permission over the Java binaries:

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

   Finally, Shift the Java contents with:

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

5. 5. Updating

   Again to Update System Java to JDK 10
   You can directly Copy & Paste the below Commands into Terminal:

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

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

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

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

   Checking or Setting the System Java Version in Use with:

   sudo update-alternatives --config java

   And for the Compiler instead:

   sudo update-alternatives --config javac

   To Switch of Java Version Just Enter the Selection Number on First, Column. :)
