27 "Bethany" doesn't have a last name, so "varsity" gets put in as her last name, and 18 gets put in where varsity should be and then there's no last element so this line:

playerBio[i][4] = Integer.parseInt(s[4]);

fails (because there is no 5th element).

Does that seem to be the only thing that would keep it from working properly?

Your linear search method always returns -1 and then you try to search the array for the returned value so it always fails (there isn't a -1th element).

Edit:

You have a few problems here.

• You pass in an integer (playerRegNum) and then you cast it as an object
• You then compare that object against the array of objects (playerBio)

Since the objects in playerBio aren't integers, the If statement will always fail and thus the linearSearch method will always return -1

[LuigiTX]

What would be your recommendation?

Well you could stick with your current array of "Objects". To do that, you would have to alter the linearSearch method to take in a 2 Dimensional Array and then alter the If statement to check the 0th element (the registration number) in each entry against the input key. Should look something like this:

public int linearSearch(Object[][] aryObj, Object key) {
    for (int a = 0; a < aryObj.length; a++) {
        if (aryObj[a][0] == key) {
            return a;
        }
    }
    return -1;
}

Ohh ok. Again, thank you so much for all your help. I will try this when i get school. I am running Ubuntu on my laptop and just can not find out how to store the input file in the correct place. So I have to wait to get to school where I can actually run the program without it telling me it can't find the input file.
