java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1 error is being received and cannot confirm why

Question

I understand that this error message indicates that I am trying to access a particular element in an array via index which is not present, or it is an invalid element trying to access outside of the length in a String. However, I have not been able to confirm where exactly this is occurring in my code with the information provided from error message:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1
    at Week3.luis_ramirez_GamesReport.readWrite(luis_ramirez_GamesReport.java:63)
    at Week3.luis_ramirez_GamesReport.main(luis_ramirez_GamesReport.java:30) 

I have reviewed previous questions posted about this but my code formats don't seem similar to others that have been posted. I have attempted to change the order of my output but since the desired output is already printing, I stopped doing so. I have also attempted to change line

String[] ints_only = Arrays.copyOfRange(record, 1, record.length);

to a value of 0 instead of 1.

Here is my code:

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;


public class luis_ramirez_GamesReport {


    public static void main(String[] args) throws IOException
    {
        {
            File fileName = new File("/Users/luisramirez/eclipse-workspace/GameScores.txt");
              readWrite(fileName);
              addGamer(fileName, "Jimmy", "189", "190", "197", "199", "198", "193", "199", "199", "188", "196");
              readWrite2(fileName);}
          }
        private static void readWrite(File fileName) throws IOException {
            

        if (fileName.exists())
        {
            BufferedReader br = null;
            String line = "";
            String csvSplitBy = ",";
            int recordCount = 0;
            //String number ="167";
            //int result = Integer.parseInt(number);
            br = new BufferedReader(new FileReader(fileName));
        
        System.out.println("-----------------------------------------------------------------------------------------------");
        System.out.println("Games Report");
        System.out.println("-----------------------------------------------------------------------------------------------");
        System.out.println("Gamer    1       2       3       4       5       6       7       8       9       10     Total");
        System.out.println("-----------------------------------------------------------------------------------------------");
        
        while ((line = br.readLine()) != null)
        {
        String[] record = line.split(csvSplitBy);
        String[] ints_only = Arrays.copyOfRange(record, 1, record.length);
        List<Integer> recordAsInts = Arrays.stream(ints_only)
            .map(str -> str.strip())
            .map(Integer::parseInt)
            .collect(Collectors.toList());
        int sum = recordAsInts.stream().reduce(Integer::sum).orElse(0);
        System.out.println(record[0] + "\t"
            + record[1] + (record[1].length() > 7 ? "\t" : "\t")
            + record[2] + (record[2].length() > 7 ? "\t" : "\t")
            + record[3] + (record[3].length() > 7 ? "\t" : "\t")
            + record[4] + (record[4].length() > 7 ? "\t" : "\t")
            + record[5] + (record[5].length() > 7 ? "\t" : "\t")
            + record[6] + (record[6].length() > 7 ? "\t" : "\t")
            + record[7] + (record[7].length() > 7 ? "\t" : "\t")
            + record[8] + (record[8].length() > 7 ? "\t" : "\t")
            + record[9] + (record[9].length() > 7 ? "\t" : "\t")
            + record[10] + (record[10].length() > 7 ? "\t" : "\t")
            + sum);
            recordCount++;
                
        }
        
        System.out.println("----------------------------------------------------------------------------------------------");
        System.out.printf("# of Gamers: %d%n",recordCount);
        System.out.println("Top Gamer: ");
        System.out.println("----------------------------------------------------------------------------------------------");
            br.close();
        }

Here is a link to an image of my output:

Here is line 30: readWrite(fileName);

Here is line 63: + record[1] + (record[1].length() > 7 ? "\t" : "\t")

Answer 1

I tried your code and it worked fine, actually i changed the path of the folder and added some other lines to make others players.

i think your problem is that you are not using the absolute path
