I get NullPointerException when I compile the following code. Can you tell me the problem in this one.

Code:

public class DrawRec {
    public static void main(String[] args) {
        Rectangle myRect;
        myRect.width = 40;
        myRect.height = 50;
        System.out.println("myRect's area is " + myRect.area());
    }
}
