java - 我的数组索引超出范围，但为什么呢？

问题描述

我收到错误消息：

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 5 out of bounds for length 5
        at score.checkWinnings(score.java:29)
        at yahtzee.main(yahtzee.java:52)

主要的第 52 行是：

points.checkWinnings(Dice, wins);

分数中的第 29 行是：

if (Dice[y] == 1)

我正在尝试获得掷骰子的分数，但不确定为什么 第 29 和 52 行会搞砸。我努力了：

for (y = 0; y < Dice[y]; y++);
//this one still gives me an error
for (y = 0; y < 5; y++);
//this one only works when I input that I want to use 5 dice

有谁知道为什么我拥有/我尝试过的东西不起作用？任何帮助将不胜感激！

我在下面包含了我的代码的相关部分：

主要的：

import java.util.ArrayList;

public class yahtzee
{
    public static void main(String[] args) 
  {
    int play = 1, scorea = 0, sum = 0;
    int[] wins = new int[15];
        
    while ((play == 1) && (sum < 15)) 
    {
      yahtzeeConfig config= new yahtzeeConfig();
      config.start();
      int[] Dice = new int[config.hand];
      //hand in score 
      sum = 0;;
      int roll = 0;
      int x, z;
      int rerolla = 0;
      dice die = new dice();
      
      System.out.println("\nHere is your roll:\n");
      //sets the dice values
      ArrayList<Integer> arList= new ArrayList<Integer>(config.hand); 
      for (x = 0; x < config.hand; x++) 
      {
        die.roll();
        Dice[x] = die.get();
        arList.add(Dice[x]);
      }
      //prints out dice values
      for (int i =0; i< config.hand; i++)
      {
        System.out.println("Die " + (i+1) + ": " + Dice[i]);
      }
      //re-rolls dice 
      do {
        for (int i =0; i< config.hand; i++)
      {
        play = inputInt("\nWould you like to reroll " + Dice[i] + " ? (1=yes, 2=no)");
        if (play == 1)
        {
          Dice[i]= die.roll();
          //roll++;
        }
        System.out.println("Die " + (i+1) + ": " + Dice[i]);
      }
    }
    //checks score
    while ((roll < 2) && (rerolla > 0));
      score points = new score();
      points.checkWinnings(Dice, wins);
      for (z = 0; z < 15; z++) {
        sum += wins[z];
      }
      scorea += points.return_score();
      System.out.println("Your total score is: " + scorea);

分数等级：

public class score
{
    private int score;
 
  public score() 
  {
    score = 0;
  }
 
  public void checkWinnings(int[] Dice, int[] wins) 
  {
    
    System.out.println("\nLet's Check Score: \n ");
 
    int x = 0, y = 0, winings = 0, winingsa = 0;
    int ones = 0, twos = 0, threes = 0, fours = 0, fives = 0, sixes = 0;
 
    //counts numbers
    for (y = 0; y < Dice.length; y++); 
    //for (y = 0; y < Dice[y]; y++);
    //for (y = 0; y < 5; y++); 
    {
      if (Dice[y] == 1) 
      {
        ones++;
      }
      if (Dice[y] == 2) 
      {
        twos++;
      }
      if (Dice[y] == 3) 
      {
        threes++;
      }
      if (Dice[y] == 4) 
      {
        fours++;
      }
      if (Dice[y] == 5) 
      {
        fives++;
      }
      if (Dice[y] == 6) 
      {
        sixes++;
      }
    }
    //upper total
    System.out.println ("Ones: " + ones);
    System.out.println("Twos: " + twos);
    System.out.println("Threes: " + threes);
    System.out.println("Fours: " + fours);
    System.out.println("Fives: " + fives);
    System.out.println("Sixes: " + sixes + "\n");
}
