    Default Arrays of Class

    I am trying to create and array of a particular class, Ant, its actually an ArrayList and a multidimensional Array, see below. What I need to know is what do I need to add or change to do this.

    Game.java
    	public void initializeBoard()
    	{
    		ArrayList board[][] = new ArrayList[27][27];
    	}
    Ant.java
    public class Ant {
     
    }

    Default Re: Arrays of Class

    create and array of a particular class
    You create an array by using the [] notation with the data type:
    TheClassName[] anArrayOfTheClassName; // define array of TheClassName objects
    anArrayOfTheClassName = new TheClassName[5]; // assign a value to the array
    If you don't understand my answer, don't ignore it, ask a question.

    In this code:

    You can create a new class called Board to manage the board functionality.
    Within the Board class, we declare a 2D ArrayList array called board to hold Ant objects.
    In the initializeBoard method, we initialize the board array and then populate it with new ArrayLists of Ant objects for each cell in the grid.
