import java.util.Random;

public class HelloWorld
{
public static void main(String[] args)
{
int flag = 1;
// 创建Random类对象
Random random = new Random();
for (int i = 1; i <= 22; i++)
{
// int j = 1;
// 产生随机数
int number = random.nextInt(2 - 1 + 1) + 1;
// 打印随机数
// System.out.println("产生一个"+1+"到"+2+"之间的随机整数："+number);
if (flag % 2 != 0)
{
if (number == 1 || i == 22)
{
System.out.println("A:" + i);
}
else
{
System.out.println("A:" + i);
System.out.println("A:" + (i + 1));
}
flag = 2;
}
else
{
if (number == 1 || i == 22)
{
System.out.println("B:" + i);
}
else
{
System.out.println("B:" + i);
System.out.println("B:" + (i + 1));
}
flag = 1;
}
if (number == 2)
{
i = i + 1;
}
// j = j + 1;
// System.out.println(i);
}
}
}

 

 

两个人A、B随意谁先开始，轮流报数 每人可以选择报一个数或者两个数，谁先数到22谁赢
