Question

So, I have a class Square and I am trying to use an array for it board. Here is my code:

public class Square{
   public int pcolor;
   public int contains;
   public int xPos;
   public int yPos;
   Square(int xp,int yp,int pc,int cont){
       xPos=xp;
       yPos=yp;
       contains=cont;
       pcolor=pc;
   }
};
Square[] board = new Square[64];
board[0].xPos=0;

This gives me unexpected token: [ on board[0].xpos=0;. Can anyone help me resolve this?

EDIT:

OK, I moved board[0].xpos=0; inside a method; now it gives me NullPointerException. What do I do?

You are trying to make a statement not inside a method or a static scope.

The statement board[0].xPos = 0; should [probably] be inside a method.

You also seem to have a redundant };

This code compiles just fine:

public class Square{
    public int pcolor;
    public int contains;
    public int xPos;
    public int yPos;
    Square(int xp,int yp,int pc,int cont){
        xPos=xp;
        yPos=yp;
        contains=cont;
        pcolor=pc;
    }
    Square[] board = new Square[64];
}

To initialize [and access] elements in board – you will have to do it in a method or in the constructor.
