需要幫助在我的程序中添加「您想再次播放」語句

Question

我正在製作Craps java程序，並且在添加「您想再次播放」語句時遇到了一些麻煩。如果你能幫助我，那將不勝感激！此外，我必須計算用戶贏/輸的遊戲數量不正常。如果您發現問題，請告訴我！

import java.util.Scanner; 
public class Lab5 { 
    static int dice2; 
    public static void main(String[] args) { 
     //variables 
     int dice1; 
     int dice2; 
     int numWins = 0; 
     int numLosses = 0; 

     //Call the welcome method 
     welcome(); 

     //fetch random numbers 

     /* 
     * ************************************************************** 
     *welcome method 
     *welcome user 
     *no parameters 
     *no return 
     **************************************************************** 
     */ 
    } 
    public static void welcome() { 
     System.out.println("Welcome to a Lucky (for me) Dice Game! \nFEELING LUCKY?!? Hope you brought lots of CASH!");{ 
     } 

     int die1 = (int) (Math.random()*6 + 1); 
     int die2 = (int) (Math.random()*6 + 1); 
     int dice = die1 + die2; 
     System.out.println("Roll: total = " + dice); 
     int numWins = 0; 
     int numLosses = 0; 
     if (dice == 7 || dice == 11){ 
      System.out.println("Woah!!! With a: "+dice+ " You WIN!!!!!!!!"); 
      numWins++; 
     } 
     else if (dice == 2 || dice == 3 || dice == 12){ 
      System.out.println("Sorry, with a "+dice+" You lose:("); 
      numLosses++; 
     } 

     while (dice != 0){ 
      int die3 = (int) (Math.random()*6 + 1); 
      int die4 = (int) (Math.random()*6 + 1); 
      int dice2 = die3 + die4; 
      System.out.println("Roll: total = "+dice2); 

      if (dice2 == 2|| dice2 == 3 || dice2 == 12){ 
       System.out.println("Sorry, with a "+dice2+" You lose:("); 
       numLosses++; 
       dice = 0; 
      } 
      else if (dice2 == 7 || dice2 == 11){ 
       System.out.println("Woah!!! With a: "+dice2+ " You WIN!!!!!!!!"); 
       numWins++; 
       dice = 0; 
      } 
      { 
       System.out.println("So far you have won " + numWins + 
       " times and lost " + numLosses + " times, "); 

       { 


       } 
      } 
     } 
}} 

這是我的輸出，當我運行它：

Welcome to a Lucky (for me) Dice Game! 
FEELING LUCKY?!? Hope you brought lots of CASH! 
Roll: total = 2 
Sorry, with a 2 You lose:(
Roll: total = 8 
So far you have won 0 times and lost 1 times, 
Roll: total = 10 
So far you have won 0 times and lost 1 times, 
Roll: total = 8 
So far you have won 0 times and lost 1 times, 
Roll: total = 3 
Sorry, with a 3 You lose:(
So far you have won 0 times and lost 2 times, 

計數器應止贏後聲明或丟失。我該如何解決？

Answer 1

要重複某些操作，可以使用循環，例如while循環或do-while循環，如果您不確定會循環多少次。要獲得用戶輸入，請使用已經導入的掃描儀對象。在do-while循環結構是這樣的......

do { 
    // code to do inside of the loop 
} while (somethingIsTrue); 

您將需要使用一些定點變量的循環變化，然後測試，而布爾檢查的內部。它可能是一個字符串，在這種情況下，你可以在你的while布爾檢查中使用String equals(...)或equalsIgnoreCase(...)方法。

所以考慮使用System.out.print(...)在代碼塊末尾提示輸入，使用掃描器獲取輸入，然後在布爾測試中測試該輸入。
