I keep getting IndexOutOfBounds error when I try to split a line from a file

Question

Well first of all hello! I am trying to read a file line by line and split that line in such a way that I can use the resulted substrings as params' for specific functions. I know it fails when it reaches "Min units consumed:". I tried to fix parts (first image below) as null also but it doesn't work. I am aware of the error but I don't know how to fix it alternatively. Some help would be awesome, cheers!

Answer 1

Although you should debug your code to find what your parts array is carrying inside, but to avoid getting IndexOutofBoundException, you should write code in a safer way, somewhat like this,

    System.out.println("currentLine: " + currentLine); // print the contents of currentLine too
    parts = currentLine.split(": ");
    if (parts.length >= 2) {
        System.out.println(parts[0] + " " + parts[1]);
    }

Answer 2

Do this

String[] split = currentLine.split(":");
for (int i = 0; i < split.length; i++)
    split[i] = split[i].replaceFirst(" ", "").trim();
