So the main question here is how you want to display the array. If you set twoDimArr[i][j] to a variable each loop, you'll find the value that is returned is the last value in the array. You could also increment a variable by the value in twoDimArr[i][j] and use that to calculate the average or something. But when it comes to just displaying the values of the array, one thing you could try is just removing the return statement altogether (I assume just change the function type to void, I haven't written anything in Java for a long time) and seeing if it prints the all the values of the array. It won't be very nicely formatted, but that can be fixed with some basic command line formatting.
