Problem with reading txt file into 2d array

Hi Everyone!

I have a problem with reading data from the txt file into the 2d array. In general, the above code is workable. The only thing that doesn't work is: userdata[row][j] = tokens[j]; The problem is that my array "userdata" gets values "null". However, if I replace this code with "System.out.println(tokens[j]);", then I can see the values from the file "UserDataFile.txt". What is wrong in my code?

And how is this a Swing / AWT / SWT / JFace question?

Where do you define userdata? (It's harder to help when we don't have all the information.)

Hi! I've already solved this problem. I just read from this array into JTable, and everything worked fine.
