Verify that Java is installed correctly

To test that the Java software has been installed correctly take the following steps:

  1. Open a CMD window (press the "Windows" key, then type "cmd" and enter).

  2. Enter the following command:

    java -version

    This command should execute and display the version of the java software that is installed. If instead the message indicates that the command or program is not found then Java has not been installed correctly. In this case enter the following command:

    set PATH

    to verify that the PATH environment variable has been set correctly.
