Basically, I'd want to know how to retrieve an array that includes another array and decrease or enlarge it. For example, Aa,b,c,d a0, b1,2 c3,4,5 d6,7,8,9 And if I want to add another integer to it, I can use java to increase it Aa,b,c,d,e a0, b1,2 c3,4,5 d6,7,8,9 e10.

Rootish Array Stack is essentially a data structure similar to array that stores array in the manner described above.

I saw an article that stated that I could utilise a List of Lists. Additionally, the List's size might change as you add/remove entries. I attempted to use a jagged array, however I cannot grow it or shrink it.
