Question

I have a class

public abstract class BoardLocation 
{
   //...
}

and another…

public abstract class Property extends BoardLocation
{
   public abstract int getRentAmt(); 
}

and finally, another…

public class Lot extends Property
{
    @Override
    public int getRentAmt()
    {
        //...
    }
}

In my Driver.java I’m doing…

BoardLocation board[] = new BoardLocation[2];
board[0] = new Lot();
board[1] = new Lot();

but when I try to call…

board[0].getRentAmt();

I get that “Can not find symbol” and it says that board[0] is a BoardLocation.

Any reason this might be? Or any fixes?

Answer 1

• you need to add that method,.getRentAmt, to BoardLocation. Perhaps make it an interface.
• Another option is to cast board[0] to Lot or Property, then call getRentAmt
