        return randumNum;
    }   
}

Area.java

package net.roseindia.simpleExample;

abstract class Area {

public abstract void getArea(); 

}

AreaOfRectangle.java

package net.roseindia.simpleExample;

public class AreaOfRectangle extends Area {

    RandomNumberGenerator random = new RandomNumberGenerator();
    int length = random.randomNumber();
    int breadth = random.randomNumber();    
    @Override
    public void getArea() {
        System.out.println("Length Of Rectangle : "+length);
        System.out.println("Breadth Of Rectangle : "+breadth);
        int area = length*breadth;      
        System.out.println("Area of Rectangle l*b = : "+area);
    }

    public static void main(String args[])
    {
        AreaOfRectangle rectangle = new AreaOfRectangle();
        rectangle.getArea();
