Splitting error- IndexOutOfBoundsException

Question

I got stuck with an issue, that I can\'t seem to solve. When splitting I should be able to get id, name, check by setting row[0], row[1], row[2]. Strangely onl

Answer 1

Probably in the time:

String[] row = line.split(",");

was called, there was no comma (,) in the line of the file/stream you're trying to read.

Answer 2

In my experience with txt files this is the best way of dealing with it:

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.regex.Pattern;

public class Cyto {

    public static void main(String[] args) throws IOException {
        ArrayList<String> names = new ArrayList<String>();
        try {

            FileInputStream dis = new FileInputStream("list.txt");
            BufferedReader br = new BufferedReader(new InputStreamReader(dis));
            String line;
            while (br.ready()) {
                line = br.readLine();
                String[] row = line.split(Pattern.quote(","));      
                System.out.println(row[1]);
                names.add(row[1]);
            }
            br.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

Use

br.ready()

instead of reading directly from stream.

Try this code,

ArrayList<String> names = new ArrayList<String>();
    try {

        DataInputStream dis = new DataInputStream(openFileInput(listLocation(listLoc)));
        BufferedReader br = new BufferedReader(new InputStreamReader(dis));
        String line;
        while ((line = br.readLine()) != null) {
            String[] row = line.split(",");
            //names.add(row[0]); // id
            names.add(row[1]); // name // ERROR AT THIS LINE
            //names.add(row[2]); // check
        }
        br.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

I think you don't need to use Pattern.quote(",") here.
