Java: Extend class as array

Question

Quick novice question: I want to extend a class as an array, like so

public class Map extends Item[][]
{

}

Is this possible, am I going about it the wrong way? Thanks!

Answer 1

Arrays are weird beasts. The have some properties, like length but they are not a class, so you can't extend them like you are attempting.

I think you are better off using composition, i.e. create a class that contains an Item[][] and then extend that class (if you need to, having one class might be enough)
