Java-一旦我的 proram 具有第一个值 运行，我如何输入新的输入？

Question

抱歉，我对编程还很陌生，我正在尝试制作一个石头剪刀布程序。它似乎工作正常，但一旦我输入（石头、布、剪刀），它就会给我我的结果，然后在控制台中终止。我怎样才能得到它，这样我就可以玩更多的回合并且它可以保存我的分数而无需再次 运行 程序。我尝试使用 for 和 while 循环，但它所做的只是打印游戏的结果，因为它循环多次，然后终止。 再次抱歉，如果有人问过这个问题或者这个问题非常明显，我到处都在寻找，却一无所知。 主要代码

public class RockPaperScissorsMain {
    
public static void main(String[] args) {

   System.out.println("Hello and welcome to Rock, Paper, Scissors");
   System.out.println("Please select either Rock, Paper or Scissors...");
   System.out.println("You can type \"Quit\" at any time to exit the game =)");

   ActionClass myMethod= new ActionClass();
            myMethod.method(); 
    }   
}

代码

package rockPaperScissors;

import java.util.Scanner;
import java.util.Random;

public class ActionClass {
                                                                                            
int winCounter=0;
int loseCounter=0;                  //COUNTER VARIABLES
int tieCounter=0;

String[] selection= {"Rock", "Paper", "Scissors"};                  
Random rand =new Random();                                                  // VARIABLES
Scanner scanny = new Scanner(System.in);
char inputChar= scanny.nextLine().charAt(0);
String opponentSelection= selection[rand.nextInt(3)];
char playerSelection= Character.toLowerCase(inputChar);


public void method() {
    
  if(playerSelection=='q') { 
    System.out.println("==============================================================================="); 
    System.out.println("THANK YOU FOR PLAYING TAKE CARE!!!");
    System.out.println("=============================================================================="); 
    System.exit(0); }
 
  else if (playerSelection=='r') {
    System.out.println("you said "+selection[0]+ "\t\t\t\t\t\t\t\t\t\t\t Your opponent chooses... " + opponentSelection);
    System.out.println("======================================================================================================================================================"); 
             }
  else if(playerSelection== 'p') System.out.println("you said " +selection[1]+ "\t\t\t\t\t\t\t\t\t\t\t Your opponent chooses... " +opponentSelection); 
  
  else if( playerSelection=='s') System.out.println("you said " +selection[2]+ "\t\t\t\t\t\t\t\t\t\t\t Your opponent chooses... " +opponentSelection);

  else System.out.println("\nSorry please select a valid option of ROCK, PAPER or SCISSORS");
    
if (opponentSelection.equals(selection[0])) { System.out.println("you TIED");   tieCounter++;}
    if (opponentSelection.equals(selection[1])) {System.out.println("you LOSE"); loseCounter++;}
    if (opponentSelection.equals(selection[2])) { System.out.println("you WIN");    winCounter++;}
    if ((inputChar=='r')||inputChar=='p'||inputChar=='s') {System.out.println("Good Game!!!");
    System.out.println("\n\n\t\t\t\t\tPlay again!! please select either Rock, Paper or Scissors...");
        System.out.println("\n\t\t\t\t\tYou've WON: "+winCounter+ " times!!!" +"You\'ve TIED " +tieCounter+" times!!! You've LOST: " +loseCounter+ " times!!!" );       
} 
    
}}

您的 ActionClass class 中有大量错误。我在这里修复了它：

import java.util.Scanner;
import java.util.Random;

public class ActionClass {

    int winCounter = 0;
    int loseCounter = 0;                  //COUNTER VARIABLES
    int tieCounter = 0;

    public void method() {
        String[] selection = {"Rock", "Paper", "Scissors"};
        Random rand = new Random();                                                  // VARIABLES
        Scanner scanny = new Scanner(System.in);
        char inputChar = scanny.nextLine().charAt(0);
        char playerSelection = Character.toLowerCase(inputChar);

        while (playerSelection != 'q') {
            String opponentSelection = selection[rand.nextInt(3)];
            if (playerSelection == 'q') {
                System.out.println("===============================================================================");
                System.out.println("THANK YOU FOR PLAYING TAKE CARE!!!");
                System.out.println("==============================================================================");
                System.exit(0);
            } else if (playerSelection == 'r') {
                System.out.println("you said " + selection[0] + "\t\t\t\t\t\t\t\t\t\t\t Your opponent chooses... " + opponentSelection);
                System.out.println("======================================================================================================================================================");
            } else if (playerSelection == 'p')
                System.out.println("you said " + selection[1] + "\t\t\t\t\t\t\t\t\t\t\t Your opponent chooses... " + opponentSelection);

            else if (playerSelection == 's')
                System.out.println("you said " + selection[2] + "\t\t\t\t\t\t\t\t\t\t\t Your opponent chooses... " + opponentSelection);

            else System.out.println("\nSorry please select a valid option of ROCK, PAPER or SCISSORS");

            if (opponentSelection.equals(selection[0])) {
                System.out.println("you TIED");
                tieCounter++;
            }
            if (opponentSelection.equals(selection[1])) {
                System.out.println("you LOSE");
                loseCounter++;
            }
            if (opponentSelection.equals(selection[2])) {
                System.out.println("you WIN");
                winCounter++;
            }
            if ((inputChar == 'r') || inputChar == 'p' || inputChar == 's') {
                System.out.println("Good Game!!!");
                System.out.println("\n\n\t\t\t\t\tPlay again!! please select either Rock, Paper or Scissors...");
                System.out.println("\n\t\t\t\t\tYou've WON: " + winCounter + " times!!!" + "You\'ve TIED " + tieCounter + " times!!! You've LOST: " + loseCounter + " times!!!");
            }
            playerSelection = scanny.nextLine().charAt(0);
        }
    }
}

基本上，您需要将逻辑放入一个循环中，这就是这一行的作用： while (playerSelection != 'q')

程序获取输入并进行R,P,S检查后，在while循环结束前最后一行再次调用scanner获取用户的下一个意图。
