自己写的一个小的剪刀——石头——布游戏的GUI程序

很简单的一个程序，建议各位初学Java的同学可以试试写写这个程序：

import javax.swing.JOptionPane;



public class Game

{

	public static void main(String args[])

	{

		JOptionPane.showMessageDialog(null,"欢迎来到石头——剪刀——布游戏!","石头——剪刀——布游戏",

						JOptionPane.INFORMATION_MESSAGE);

		int man,computer;

		int player,comp;

		man = computer = 0;

		while(man != 2 && computer != 2)

		{

			String string = JOptionPane.showInputDialog(null,"请输入你的指令:石头(1),剪刀(2),布(3):"

					,"输入窗口",JOptionPane.QUESTION_MESSAGE);

			player = Integer.parseInt(string);

			comp = (int)(System.currentTimeMillis() % 3) + 1;

			if((player == 1 && comp == 2) || (player == 2 && comp == 3) || (player == 3 && comp == 1))

			{

				man++;

				computer = 0;

				JOptionPane.showMessageDialog(null,"你赢了!","石头——剪刀——布游戏",

						JOptionPane.INFORMATION_MESSAGE);

			}

			else if((player == 1 && comp == 3) || (player == 2 && comp == 1) || (player == 3 && comp == 2))

			{	

				computer++;

				man = 0;

				JOptionPane.showMessageDialog(null,"你输了!","石头——剪刀——布游戏",

						JOptionPane.INFORMATION_MESSAGE);

			}

			else 

			{

				man = computer = 0;

				JOptionPane.showMessageDialog(null,"这局打平!","石头——剪刀——布游戏",

						JOptionPane.INFORMATION_MESSAGE);

			}

		}

		if(man == 2)

		{

			JOptionPane.showMessageDialog(null,"恭喜你取得人机战的胜利!","石头——剪刀——布游戏",

						JOptionPane.INFORMATION_MESSAGE);

		}

		else

		{

			JOptionPane.showMessageDialog(null,"很遗憾你落败了.","石头——剪刀——布游戏",

	}

}
