How to Install Oracle Java JDK on Kali Linux 32/64-bit​


    1. Download Oracle Java SE JDK8 for Linux:
      Link:

    2. Double-Click on the tar.gz Archive and Extract into
      /tmp

      Or from Shell:
      tar xvzf ./jdk-14.0.2_linux-x64_bin.tar.gz -C /tmp/
    3. Open a Terminal Window
      (Press “Enter” to Execute Commands)
    4. Relocate JDK 8su
      If Got “User is Not in Sudoers file” then:

      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 holder
      chown -R root:root /tmp/jdk-14*
      Reiterate the Execution Permission over the Java binaries
      chmod -R +x /tmp/jdk-14*/bin
      Finally Shift the Java contents with
      mv /tmp/jdk-14* /usr/lib/jvm/

    5. Installing Oracle Java JDK 14.0.2
      You can directly Copy & Paste the Commands into Terminal…

      update-alternatives --install
      /usr/bin/java java /usr/lib/jvm/jdk-14*/bin/java 1065

      update-alternatives --install
      /usr/bin/javac javac /usr/lib/jvm/jdk-14*/bin/javac 1065

      update-alternatives --install
      /usr/bin/jar jar /usr/lib/jvm/jdk-14*/bin/jar 1065

      update-alternatives --install
      /usr/bin/javaws javaws /usr/lib/jvm/jdk-14*/bin/javaws 1065

      Checking or Setting the System Java Version in Use with
      update-alternatives --config java

      To Switch of Java Version Just Enter the Selection Number on First Column. 🙂

    6. Setting JAVA_HOME User Environment Variable (Optional)
      su [myUserName]
      Or simply:
      exit
      And Edit the Bash environment Configuration file
      nano $HOME/.bashrc
      Append:
      export JAVA_HOME=/usr/lib/jvm/jdk-14*[uX]
      Replace the [uX] Looking for the Installed Java 14.0.2 Version with:
      ls /usr/lib/jvm/
      Ctr+x to Save & Exit from nano Editor 🙂
      Load New Bash Config:
      bash
    7. Test New Java JDK 8 Installationjava -version
