The code you posted is an applet. Applets are run using a browser (or appletviewer). You can not run them as a java application, unless you write code to handle setting up the applet as an application.
When you run a java application, the JVM looks for a method named main. Since your applet does not a method named main, you got the error.
Here's a page with some online tutorials.

You create source code and compile it just like you compile a java application. If you use the command line, then you use javac.
You need to create a html file with correct html.
You can run an applet using appletviewer filename.html.

If online tutorial don't work for you, then I believe you will either need a tutor/mentor or it will take you a long time to learn. If you are proficient in another computer language, you may learn quicker. I am self-taught. I went through tutorials and wrote code. I am not a computer professional, so I am not expert with java and others may give you different suggestions.
