            Player3.guess();
            System.out.println("Player one guessed\t"+Player1.i);
            System.out.println("Player two guessed\t"+Player2.i);
            System.out.println("Player three guessed\t"+Player3.i);
            if(Player1.i==j||Player2.i==j||Player3.i==j){
                flag=false;
            }
        }while(flag);
        System.out.println("We have a winner!");
        boolean ans1=Player1.i==j;
        boolean ans2=Player2.i==j;
        boolean ans3=Player3.i==j;
        System.out.println("Player one got it right?\t"+ans1);
        System.out.println("Player two got it right?\t"+ans2);
        System.out.println("Player three got it right?\t"+ans3);
        System.out.println("Game is over!");
    }
}

结果如下：
