Question

I am confused in Java!

Answer 1

Import java.util.Random;

class Building
{
    private int w, h;
    private int numberOfWins;

    public Building(int width, int height)
    {
        w = width;
        h = height;

        // generating random windows. can be between 1 and 10
        Random rand = new Random();
        numberOfWins = rand.nextInt(9) + 1;
    }

    public int getWidth() { return w; }
    public int getHeight() { return h; }
    public int numberOfWindows() { return numberOfWins; }

    public String toString()
    {
         return "a black building, width: " + width + ", height: " + height +
                    ", has " + numberOfWins + " windows"; 
    }
}

----------------------------------------------------

then you can create some Building objects and output them!
