(游戏:挑一张牌)编写程序，模拟从一副 52 张的牌中选择一张牌。程序应该显示牌的
大小(Ace、2、3、4、5、6、7、8、9、10、Jack、Queen、King)以及牌的花色(Clubs
(黑梅花)、Diamonds(红方块)、Hearts(红心)、Spades(黑桃))。下面是这个程序的
运行示例:
The card you picked is Jack of Hearts

package myjava;
import java.math.*;
import java.util.Scanner;
public class cy {
	public static void main(String[]args)
	{
		int huase=(int)Math.random()*4+1;//1(Clubs),2(Diamonds),3(Hearts),4(Spades)
		int num=(int)Math.random()*13+1;//1-13的随机数
		if(huase==1)
		{
			System.out.println("The card you picked is "+num+"of Clubs");
		}
		if(huase==2)
		{
			System.out.println("The card you picked is "+num+"of Diamonds");
		}
		if(huase==3)
		{
			System.out.println("The card you picked is "+num+"of Hearts");
		}
		if(huase==4)
		{
			System.out.println("The card you picked is "+num+"of Spades");
		}
	}
}

运行结果：
