ActionListener eListener = new AddEnterListener();
AddActionListener is probably a void method.
I very highly doubt it returns an ActionListener or a subclass of ActionListener.
First off,
int[][] tArray = new int[index][2];
means
int [][] tArray = new int[0][2];
which means that there are 3 values in row 0 and no values in any other row.
