Java实现简单的贪吃蛇游戏

本文实例为大家分享了Java实现简单贪吃蛇游戏的具体代码，供大家参考，具体内容如下
代码
启动类

package snake; import javax.swing.*; //游戏的主启动类public class StartGame {public static void main(String[] args) {JFrame frame = new JFrame("贪吃蛇"); frame.setBounds(10,10,900,720); frame.setResizable(false); //窗口不可调整frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); //正常游戏界面都应该在面板上frame.add(new GamePanel()); frame.setVisible(true); }}

游戏画板
