也可以，
拼图的也可以，就是用键盘能控制移动就行。

这是我的源代码，运行不出来，有错误。高手帮忙！

class MYWin extends JFrame implements KeyListener,FocusListener{
JButton button[]=new JButton[8];
public MYWin(String s){
super(s);
Container con=getContentPane();
con.setLayout(new FlowLayout());
for(int i=0;i<=8;i++){
button[i].addKeyListener(this);
con.add(button[i]);
}
button[i].requestFocusInWindow();
button[i].addFocusListener(this);
setBounds(100,100,200,200);
validate();
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
