Array problem

Array problem -- zombek --

Hi.
I have a multidimensional array of "Square" objects:

private Square

_board;
In the constructor of the class which _board is a member I have the following code:

for(int i = 0; i < BOARD_WIDTH; i++){
for(int j = 0; j < BOARD_HEIGHT; j++){
_board

= new Square();
}
}
In an other method I want to get to one of the Square class' fields like this:

if (_board

.State == Square.State.OCCUPIED){...}
But I get the following error:
An object reference is required for the nonstatic field
'square.State.get'

I don't know what's wrong.

Hi zombek,

What is State defined as? I'm guessing that you want it to be a static property or enumeration on the Square class, right? If that is correct, then you need to declare it as "static" like this:

public static enum State {
on,
off
}

or something like that.
The problem is that the statement:

.State == Square.State.OCCUPIED){...}

is trying to reference the State property on the Square class - which it cannot see.

Hi zombek,

I wrote a reply, but I don't see it, so here goes again:

This line

.State == Square.State.OCCUPIED){...}

is looking for a static property on the Square class, but cannot see it. How is it defined?
