Java Pinball Game code _java based on swing implementation

This example describes the Java Pinball game code based on swing implementation. Share to everyone for your reference.

The main functional code is as follows:

code as follows:

Create an action listener from an anonymous inner class

If you choose to start, the thread object is created
