You need to update your Windows path to include your %JAVA_HOME%\bin directory. %JAVA_HOME% is the directory that you installed Java into and is also an environment variable that you need to configure for command line execution of your applications. You can edit both of these in the Windows control panel and you should restart.
When you run java -version you will see the internal version number. This is explained here: https://en.wikipedia.org/wiki/Java_version_history.
Basically, you can ignore the 1. when reading version number. The _xxx is a reference to the most recent patch or build release.
CMD does not recognize the java -version command?
But what's in PATH though? Remove old Java directories from this variable and keep only the right one, better to write just "${JAVA_HOME}/bin" instead of full paths More on reddit.com

February 4, 2011CMD shows nothing when putting 'java -version'
After you install Java you have to set up your PATH environment variable to include the JDK. This tells Windows where to look whenever you're trying to execute java or javac. To do this in windows just type Environment Variables into your start menu. Go into it, double click on PATH to open it, scroll to the end, put in a semi-colon and the path to your JDK. Then re-launch CMD (you have to close and reopen the window) and you should be able to do Java --version and get a response. More on reddit.com
