用java写一个贪吃蛇游戏并且包括文件名且能运行

好的，下面是一个简单的Java贪吃蛇游戏的代码，其中包括文件名，并可以运行。

        }
        if ((key == KeyEvent.VK_UP) && (!downDirection)) {
            upDirection = true;

            leftDirection = false;
        }
        if ((key == KeyEvent.VK_DOWN) && (!upDirection)) {
            downDirection = true;
            rightDirection = false;
            leftDirection = false;
        }
    }

    @Override
    public void keyTyped(KeyEvent e) {
        // do nothing
    }

    @Override
    public void keyReleased(KeyEvent e) {
        // do nothing
    }
}

将上面的代码保存为Snake.java文件，然后在命令行中进入该文件所在目录，执行以下命令即可运行游戏：

javac Snake.java
java Snake

这样就可以运行Java贪吃蛇游戏了。
