石头剪刀布简单的Java使用方法

Question

所以我今天的任务是用方法制作一个石头剪刀布游戏。我对代码的第一个问题是，我需要它来询问用户是否要再次玩。 （y 或 n） 此外，我需要实现评分，如果用户赢了，则得 1 分，如果他们输了，则为 -1，并且每次他们再次玩时将该分数添加到总分中。关于如何实现这一点的任何想法？或者我需要对我的代码进行更改的内容。此外，我是一个菜鸟，非常抱歉丑陋的格式，并随时批评每一个小细节，我吸收了我所能吸收的所有信息。

 public static void main(String[] args){
 boolean tie = true;
    do{
        String computer = computerChoice();
        String user = userChoice();
        tie = (computer.compareTo(user) == 0);
        determineWinner(computer, user);
    }while(tie);
  }
  public static String computerChoice( ){
  Random rand = new Random();
 int cinput = rand.nextInt(3)+ 1;
  String computer = "thing";
  if (cinput == 1)
  computer = "Rock";
   if (cinput == 2)
  computer = "Paper";
 if (cinput == 3)
  computer = "Scissors";
    return computer;
  }
  public static String userChoice(){
  Scanner sc = new Scanner (System.in);
  String user = "default";
  do{
    System.out.println("choose your weapon(Paper,Scissors or Rock)");
    user = sc.nextLine();
  }
  while (isValidChoice (user) == false);
  return user;
  }
  public static boolean isValidChoice(String choice){
  boolean status;
  if (choice.compareTo("Rock")== 0)
    status = true;
  else if (choice.compareTo("Paper")== 0)
    status = true;
  else if (choice.compareTo("Scissors")== 0)
    status = true;
  else{
    status = false;
    System.out.println("Error! Make sure you are capitalizing your                    choices");
}
return status;
  }
  public static boolean determineWinner(String computer, String user){
  System.out.println (" Computer Choice: " + computer);
  System.out.println ("Your Choice : " + user);
  if (computer.compareTo( "Rock" ) == 0 && user.compareTo  ("Scissors") == 0)
  System.out.println (" Computer wins! Better luck next time!");
  if (computer.compareTo("Scissors")== 0 && user.compareTo("Paper") == 0)
  System.out.println (" Computer wins! Better luck next time!");
  if (computer.compareTo("Paper") == 0 && user.compareTo("Rock") == 0)
  System.out.println (" Computer wins! Better luck next time!");
   if (computer.compareTo("Rock") == 0 && user.compareTo("Paper") == 0)
   System.out.println (" You win!!");
  if (computer.compareTo("Scissors") == 0 && user.compareTo("Rock") == 0)
  System.out.println (" You win!!");
  if (computer.compareTo("Paper") == 0 && user.compareTo("Scissors") == 0)
  System.out.println (" You win!!");
  else if (computer.compareTo(user) == 0 ){
    System.out.println(" Tie! the game must be played again.");
    return false;
  }
  return true;
}
}

我的教授给我们举了一个例子的输出是：

Choose your weapon!
1. Paper
2. Scissors
3. Rock
5
 Choose your weapon!
 1. Paper
 2. Scissors
 3. Rock
  1
 You chose paper!
 I choose rock!
 I have been vanquished!
 We have matched wits 1 times, and your score is 1
 Do you want to play again (y or n)? y
 Choose your weapon!
 1. Paper
 2. Scissors
 3. Rock
 1
 You chose paper!
  I choose paper!
  We are equally matched. You are a worthy adversary.
  We have matched wits 2 times, and your score is 1
  Do you want to play again (y or n)? n

Answer 1

这是完成的代码。我添加了两个函数，一个用于调用实际游戏，另一个用于检查玩家是否想再次玩。另外，最后还有最后一句
