I. Introduction

If you want to make this game, it is best to have learned AWT or Swing programming, know the knowledge of the graphical interface, and know how to draw. This game can help you better lay a solid foundation.

2. Pinball game

(1) Analyzing the game

The rules of the pinball mini-game, the ball will move in the opposite direction when it hits the racket or the interface, and the game ends when it cannot touch the racket
