Storing user input into 2-d Array

I'm trying to store two decimal numbers that the user will input into a two-dimensional array. The entire program is a GUI so, I'm only posting a little of the code

The problem I'm having is getting the user input to append to the next line in the text box.

Example, user enters "1" and "2" and presses the action button, then enters "3" and "4" In the output text box it should read as:

1 2
3 4

But right now it overwrites my number output.

Thanks in advance for the help!

It appears to me you are updating everything right, you are just not appending the right values. Also where do you read in the data? You could be only reading from the user once.

Welcome to the Ranch

And I shall be pedantic and remind you there is no such thing as a 2D array in Java; there are only arrays of arrays.

Thank you for the PM; if you look up arrays in the Java™ Tutorials, you find a "multidimensional array" is actually an array of arrays.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link:
