Q3: Java这个程序能显示小方块但是移动不了，请问哪里出错了

repaint调用的时候会调用paint方法，但是你看看你的paint方法，每次绘制的图都是一样的，不会根据你按键的动作改变绘制的图形，所以方块动不了。

可以把方块的坐标设置成全局变量。然后在按键的监听事件里根据按下的键改变坐标，再调用repaint方法，先清除地图信息后(先清除是为了避免上一次绘制的方块还在)再重新绘制方块的位置，就可以了。

也就是说，paint方法里，你需要移动的方块的坐标不要写成定值。

Q4: Java 图像问题：这个程序的功能是红色方块在红色文字上从左到右循环移动。 我只能读懂前面部分

问题一：1,25表示字符串绘制冲（1,25）开始。

问题二：这个是用来捕捉异常的，对程序来说，他知道这里有可能出现异常，为了程序能正常运行，就需要处理。它尝试运行try里面的代码，如果出现异常就交到catch里面处理。也就是说有异常就捕捉，没异常就继续运行，但是不能不设置捕捉。

问题三：方块沿着水平方向100毫秒移动8，当移动的距离大于160的时候，又冲从新回到原来的地方（i = 1；）然后有继续原来的运动循环

手打的，望采纳，Thanks！
