Getting an error while trying to split two tokens

November 4, 2022

I keep getting an out of bounds exception error when adding a second Entry variable.
The file that I’m trying to read in has a last line that just says "END"
the rest of the lines are formatted such as

1839,Sutter's Fort founded

and the file ends with:

END

      while (myReader.hasNextLine()) {
        String string = myReader.nextLine();
        if (string == "END") break;
         String[] parts = string.split(",");
        String part1 = parts[0];
        String part2 = parts[1];
         Entry a = new Entry(part1, part2);
         array[10].addHead(a);          // printing out the values
         System.out.println(part1 + " " + part2);
         System.out.println(array[10].removeHead().key);
      }

I tried adding a break statement if the String were to equal "END" but it seems as though it either won’t break out or just ignores it.

>Solution :

You need to use String.equals str == otherStr only returns true if both sides are the exact same object

 while (myReader.hasNextLine()) {
    String string = myReader.nextLine();
    if (string.equals("END")) break;
     String[] parts = string.split(",");
    String part1 = parts[0];
    String part2 = parts[1];
     Entry a = new Entry(part1, part2);
     array[10].addHead(a);          // printing out the values
     System.out.println(part1 + " " + part2);
     System.out.println(array[10].removeHead().key);
  }
