JAVA程序源代码贪吃蛇.docx

1、JAVA程序源代码贪吃蛇 贪吃蛇源代码 将Location、LocationRO、SnakeFrame、SnakeModel、SnakePanel放到命名为snake的文件夹里，主函数MainApp放到外面运行主函数即可实现。主函数package snake;import javax.swing.*;import snake.*;public class MainApp public static void main(String args) JFrame.setDefaultLookAndFeelDecorated(true); SnakeFrame frame=new SnakeFrame

2、(); frame.setSize(350,350); frame.setResizable(false); frame.setLocation(330,220); frame.setTitle(贪吃蛇); frame.setVisible(true); package snake;public class Location private int x; private int y; Location(int x,int y) this.x=x; this.y=y; int getX() return x; int getY() return y; void setX(int x) this.
