java.lang.ArrayIndexOutOfBoundsException mistake

Question

I am trying to search through a file to print out scores. Here is what I have:

 while (input.hasNextLine()) {
        String record = input.nextLine();
        String[] field = record.split(" ");
        if(field[1].equals(targetState)) { 
            System.out.print(field[0] + ": ");
            System.out.println(field[2]);
        }
    }

And the data in file looks like this:

2007,Alabama,252

When I ran this code, I get that java.lang.ArrayIndexOutOfBoundsException error. I just wonder what is wrong with the code

Thanks

Or just read the exception. It tells you the index, the size of the collection, and the line where it occurred ... — clcto

Right -- read the very excellent exception. It tells you exactly what's wrong and where. — Hot Licks

You need to split using comma and not space. Change this

    String[] field = record.split(" ");

to

   String[] field = record.split(",");

As you don’t have the spaces in your input string, so it is not getting split and hence the output array does not have multiple items, leading to ArrayIndexOutOfBoundException
