這篇文章主要為大家詳細(xì)介紹了java swing框架實(shí)現(xiàn)貪吃蛇游戲，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了java swing實(shí)現(xiàn)貪吃蛇游戲的具體代碼，供大家參考，具體內(nèi)容如下

1、編寫(xiě)main方法

package game;
import java.awt.Graphics;

import javax.swing.*;
public class snakeMain extends JFrame {
 public snakeMain() {
 snakeWin win = new snakeWin();
 add(win);
 setTitle("̰貪吃蛇v1.0");
 setSize(435,390);
 setLocation(200, 200);
 setVisible(true);
 }
 public static void main(String[] args) {
 new snakeMain();
 }
}

2、編寫(xiě)實(shí)體類(lèi)

package game;
public class snakeAct {
 private int x;
 private int y;
 public int getX() {
 return x;
 }
 public void setX(int x) {
 this.x = x;
 }
 public int getY() {
 return y;
 }
 public void setY(int y) {
 this.y = y;
 }
 
}

3、編寫(xiě)主要程序

package game;
