如何用JAVA实现聊天窗口的抖动效果，最好是具体代码
public class ShakeFrame extends JFrame {
private JButton btn = new JButton("Click me!");
public ShakeFrame() {
super("抖动窗口");
this.setSize(300, 200);
this.setVisible(true);
this.setResizable(false);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setLayout(null);
btn.setBounds(10, 10, 100, 30);
this.add(btn);
btn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
int x = ShakeFrame.this.getX();
int y = ShakeFrame.this.getY();
for (int i = 0; i 20; i++) {
if ((i 1) == 0) {
x += 3;
y += 3;
} else {
x -= 3;
y -= 3;
}
ShakeFrame.this.setLocation(x, y);
try {
Thread.sleep(50);
} catch (InterruptedException e1) {
e1.printStackTrace();
}
}
}
});
}
public static void main(String[] args) {
new ShakeFrame();
}
}

Q2: java 里如何实现打这样一张图载入后，上下左右控制人物行走呢？
这个叫人物行走方位图吧，一般多用于制作RPG类游戏，比较常见的一种做法是，取坐标：你定义一个矩形，刚好框住一个人，这样就把一个人物动作取出来了，然后控制框的坐标移动，取下一个动作，直到一个动作循环完成！一楼的办法也可以，不过是切重新切图片，比较麻烦，载入的时候，也比较麻烦！
Q3: Java 鼠标控制人物移动，地图随人物移动
去学习A星寻路，可以得到最短路径，其中也包括了绕开障碍物的代码，然后就是动画的图片切换了，如果说要地图跟随主角移动，那个应该是滚屏操作，也就是说你主角往右走，超过窗口或者屏幕（全屏）坐标一半的时候，地图整个往左移动，速度和主角的一样就出来效果了。如果你看不懂A星的话，那咂就给你一段BFS的C++语言代码，自己转换成JAVA代码写法（就是改些关键字，有不少经典的游戏算法都来自C/C++）就可以了，这个是简化版的A星寻路，一样可以找到最近的路径，你把path 这个路径记录下来再换算成像素位置就可以得到行走的具体步伐了...
