Multi-Dimensional Arrays

Question

I am working in Java and am wondering, are multi-dimensional arrays like grids where rows are elements and columns are dimensions, or are they hyper-geometric figures that we can't see?

Answer 1

A 1D array is like a list, a 2D array is like a table with columns and rows, a 3D array is like a cube, x, y and z and anything more than that would be hyper-geometric. You could represent a cube with time with a 4D array.

Answer 2

Sometimes it's useful to think of multidimensional arrays as geometric: lists, tables, cubes. Other times, such as when the arrays aren't of equal length, it's not. They might be:

• lists of tables
• lists of lists of lists
• tables of cubes

At some (early) point it's time to make some classes.
