You need to install Java Development Kit. If you are using Debian based system (Ubuntu, Linux mint, etc.) just type in terminal: sudo apt-get install openjdk-8-jdk. On windows you must visit Java website and download Java JDK manually.

To check if you have installed Java JDK, type in console javac -version, you should see message like this: javac 1.8.0_91
