You've probably seen the prompt to update Java. If you have the Ninite Updater installed on your computer - and you do if I've worked on it - run that instead of worming your way through the Java prompts, trying to avoid 3rd-party software they'd like to shove onto your computer.
Current version of Java is now 8.0, version 121
If you're still unsure you can go to the Java check page and verify or update from there. Or ask for help.
