I have included the txt file that needs to be read into separate 1 dimensional string arrays. I have managed to complete the rest of my assignment by making a 2 dimensional array within the code that works, but this is where the problem lies. I need to be able to read it from the file into into 2 separate 1 dimensional string arrays.

parallel Arrays? is the number/name combination connected? If so, create an object that holds the the number and name.
Second,

String[] array1, array2;
array1 = new String[numberOfItems];
array2 = new String[numberOfItems];

voila, 2 separate 1 dimensional arrays;

Thank you for the help but my big problem is getting those values from the txt file into the 2, 1dimensional arrays. That what I've been struggling with. Its really frustrating. This is what the txt file looks like.

well, use the scanner to get nextLine(); if you want the numbers in one array, and the names in the other, in your while loop, switch between putting the input from one array to the other every loop.

The way I would do it, is put the number and name on the same line separated by : or some other unused character in the file, use nextline() and then split on whatever i separated with. String[] is returned, which I can do String[0] for the first(number?) and String[1] for the second(name?). Then I would create a new Object of Account(or whatever the data is for), which would accept the parameters of number and name(will have to parse the number for an integer or double). Then I would add that object to a Vector<Account> or ArrayList<Account> and have my Accounts at a fingertips access.

Also, You should have a look at MacOSXNerd101's tutorial on Moving Away From Parallel Arrays
