用java来写一个简单的猜拳小游戏

package a1;
import java.util.Scanner;
public class Caiquan {
  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    int c = 1;
    while (c == 1){
      System.out.println("玩家请出拳");
      //玩家出拳
      int b = sc.nextInt();
      String bHand = getHand(b);
      // 2 电脑开始出拳(生成一个随机数)
      int a = (int)(Math.random()*3);
      String aHand = getHand(a);
      if((a == 0 && b == 2) || (a == 1 && b == 0) || (a ==2 && b ==1)) {
        System.out.println("电脑出拳-" + aHand + ";玩家出拳-" + bHand + "；电脑胜利");
      }else if((a == 0 && b == 0) || (a == 1 && b == 1) || (a ==2 && b ==2)) {
        System.out.println("电脑出拳-" + aHand + ";玩家出拳-" + bHand + "；平局");
      } else {
        System.out.println("电脑出拳-" + aHand + ";玩家出拳-" + bHand + "；玩家胜利");
      }
      System.out.println("是否继续？y-继续 n-退出");
      String tar = sc.next();
      if("n".equals(tar)) {//equals()判断两个字符串的值是否相等
        c = 2;
      }
  }
    System.out.println("游戏结束！!!");
  }
  public static String getHand(int h) {
    if(h == 0)return"剪刀";
    if(h == 1)return"石头";
    if(h == 2)return"布";
    return"";
  }
  }
