Pass 2D array between methods

I am struggling to pass my 2D array between classes. The following getMethod should return a valid 2D array:

public String[][] getResults(){
return (resultSet);

However when i try to access from another class my first attempts fall woefully short:

String test[][]=newData.getResults();

When I try to access elements they are all null. how do i accomplish this?

All help very welcome.

Welcome to the Ranch!

Where and how have you initialized resultSet?

Welcome again

I am afraid I am going pedantic: there is no such thing in Java™ as a 2D array. There are arrays of arrays, however.
It is sorta covered in the JavaRanch Style Guide.
