Creating arraylist of arrays

Question

I\'m trying to create an array list of string arrays. When I am done, I want the array list to look like this:

[0,0], [0,1], [1,0], [1,1,]

Answer 1

This is because you're adding t2 to all of the entries. Each time you overwrite t2 you're changing all the values. This is because t2 isn't being passed by value, it is being passed by reference and saved by reference.
