How can I create a 2 dimensional dynamic length array?

Question

I want to create a 2-dimensional array, without knowing the size of the first dimension.

For example I have an unknown number of rows, when I create an array. Ever

Answer 1

As long as I know, we cant instantiate array without knowing its size. Why dont you try a Array of List? Like this:

List[] a = new List[yourDesireColumnNumber];

With List, add, select, input elements is trivial. If you want to give it as parameter in other functions, just define Type.
