用java做一个较为完整的贪吃蛇
@[
------ 因为有个关于游戏的兴趣课没去，该课讲得是贪吃蛇，所以自己一直都想尝试去做下的，借这个寒假的机会，就自己学了，自己做的还是较为全面的，有登陆界面，可以选择游戏难度，游戏过程有背景音乐，死亡时也有特殊音乐。
（一）制作游戏登陆界面
1.1添加游戏开始背景图
1.2设置开始与退出登陆
1.3添加游戏模式选择框

try {

} catch (Exception e) {
e.printStackTrace();
}
View view=new View();
}
}
（二）制作游戏运行过程
2.1画出蛇的运行范围
2.2添加上部标题图
2.3设计蛇的移动
2.4利用计时器循环运行
2.5添加游戏背景音乐
