無法弄清楚爲什麼它不能正確解析

Question

所以，我正在爲這個課程進行這項任務。這是一個Java類，我應該製作一個遊戲，它會擲出兩個骰子，將它們加起來，並將它們添加到輪到分數中。然後問你是否想繼續玩。當你的回合得分達到20分，或者你決定通過時，它就會進入電腦。它應該打印每個回合的分數，然後當有人擊中100分時，它宣佈獲勝者。然而，無論如何，每回合結束時的得分是0，無論我運行多少次。當玩家擲出1時，他們的回合得分被取消，並且移動到另一個玩家，並且如果他們擲出雙倍1，則他們目前失去了他們的所有積分。這是我的代碼，你能找出爲什麼分數變量不更新嗎？謝謝。

import java.util.Scanner; 
import java.util.Random; 
public class PlayPig { 

    public static void main(String[] args) { 
     // TODO Auto-generated method stub 
     Scanner scan = new Scanner(System.in); 
     int player1 = 0; 
     int player2 = 0; 
     int a, b, c, player1turn, player2turn, input; 
     int pig = 1; 
     Random r = new Random();

       a = r.nextInt(6)+1; 
       b = r.nextInt(6)+1;

         if (a == 1 && b == 1){

      System.out.print("Player 1 wins");

Answer 1

主要問題是，您指定當前得分的else條件在錯誤的塊中。 （這些的）：

else { 
    player1turn = a+b ; 
} 

試試這個代碼：

public static void main(String[] args) { 
    // TODO Auto-generated method stub 
    Scanner scan = new Scanner(System.in); 
    int player1 = 0; 
    int player2 = 0; 
    int a, b, c, player1turn, player2turn, input;   
    int pig = 1; 
    Random r = new Random(); 
    do{ 

     do { 

      player1turn=0; 
      a = r.nextInt(6)+1; 
      b = r.nextInt(6)+1; 
       if(a==1 || b==1){ 
        if (a == 1 && b == 1){ 
         player1 = 0; 
         break; 
        } 
        else if (a==1 || b==1){ 
         player1turn=0; 
         break; 
        } 
       }else { 
        player1turn = a+b ; 
       } 
      player1 += player1turn; 
      System.out.println("Player1 score is " + player1 + " and player2 score is " + player2); 
      System.out.print("Do you want to keep playing? Enter 1 to continue. Enter any other number to pass."); 
      input = scan.nextInt(); 
       if (input != 1){ 
        break; 
       } 
     } while (player1turn <= 20); 

     do{ 
      player2turn=0; 
      a = r.nextInt(6)+1; 
      b = r.nextInt(6)+1; 

      if(a==1 || b==1){ 
       if (a == 1 && b == 1){ 
        player2=0; 
        break; 
       } else if (a==1 || b==1){ 
        player2turn=0; 
        break; 
       }    
      }else { 
       player2turn = a+b ; 
       player2 += player2turn; 
      } 

     }while (player2turn<=20); 

    } while (player1 < 100 || player2 < 100); 
    if (player1>player2) 
     System.out.print("Player 1 wins"); 
    else 
     System.out.print("Player 2 wins"); 

}

我已經修改了，如果循環。 你可以試試這個：

import java.util.Scanner; 
import java.util.Random; 
public class PlayPig { 

public static void main(String[] args) { 
    // TODO Auto-generated method stub 
    Scanner scan = new Scanner(System.in); 
    int player1 = 0; 
    int player2 = 0; 
    int a, b, c, player1turn, player2turn, input; 
    int pig = 1; 
    Random r = new Random(); 
    do{ 
     do { 
      player1turn=0; 
      a = r.nextInt(6)+1; 
      b = r.nextInt(6)+1; 
       if (a == 1 && b == 1){ 
         player1=0; 
         break; 
       } 
       else if((a== 1 && b!= 1) || (a!=1 && b== 1){ 
        player1turn=0; 
        break; 
       } 
       else{ 
        player1turn= a+b ; 
       } 
       player1= player1+player1turn; 
      System.out.println("Player1 score is " + player1 + " and player2   score is " + player2); 
      System.out.print("Do you want to keep playing? Enter 1 to  continue. Enter any other number to pass."); 
      input = scan.nextInt(); 
       if (input != 1) 
        break; 
     } 
     while  
      (player1turn <= 20); 
     do{ 
      player2turn=0; 
      a = r.nextInt(6)+1; 
      b = r.nextInt(6)+1; 
      if (a == 1 && b == 1){ 
         player2=0; 
         break; 
       } 
       else if((a== 1 && b!= 1) || (a!=1 && b== 1){ 
        player2turn=0; 
        break; 
       } 
       else{ 
        player2turn= a+b ; 
       } 
       player2= player2+player2turn; 
     } 
     while 
      (player2turn<=20); 
    } 
    while 
     (player1 < 100 || player2 < 100); 
    if (player1>player2) 
     System.out.print("Player 1 wins"); 
    else 
     System.out.print("Player 2 wins"); 

}}
