似乎無法找出問題所在

Question

import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Scanner;

public class Salaries
{
   public static void main(String[] args) throws FileNotFoundException 
   {
      String filename = args[0];
      Scanner in = new Scanner(new File(filename));


      int sum = 0;

      in.nextLine();

      while(in.hasNextLine())
      {
        int totalSalary = 0; 

        String line = in.nextLine();
        String[] lineArray = in.nextLine().split("\\s+");

        for(int i = 0; i <= lineArray[i].length(); i++)
        {
            String arrayInts = lineArray[i];

            if(lineArray[i].contains("$"))
                {


                  arrayInts = arrayInts.replace("$","");
                  arrayInts = arrayInts.replace(",","");
                  totalSalary = Integer.parseInt(arrayInts);
                  sum = sum + totalSalary;
                }  
         }        

       }
      System.out.printf("$%,d\n",sum);
      sum = 0;




    }
}

我不明白為什么我不斷收到越界錯誤。 我的代碼應該通過一個文本文件並收集數字並創建總數。

Answer 1

我懷疑你在這行代碼上越界了：

for(int i = 0; i <= lineArray[i].length(); i++)

（我不應該在這里猜測；問題的詳細信息應該在您的原始帖子中。）

首先，您可能想要針對lineArray.length進行測試，而不是lineArray[i].length() （這是lineArray的特定String元素的lineArray ）。 其次，您應該使用i < ...而不是i <= ... 。 數組的實際長度不是數組的合法索引。

因此，將該行更改為：

for(int i = 0; i < lineArray.length; i++)
