This is a great time to get Eclipse or NetBeans. These are development tools for your computer that allow you to write and run Java programs.

Done? Open the tool and create a Java project. If the project doesn't come with a class, create a class (File, New, Class). If possible, create a main method with it.

Hopefully, your project looks somewhat like this. By clicking the play/run button in the tool, you can assemble and run your Java program.

Psst: after //, we can put comments to help us take notes and understand what the code does.
