A Simple program

Hi I have written the following code:

class FirstRectangle{ public int rectArea(int l,int b){ int farea = l*b; System.out.println("Required Area::"+farea); return farea; }//method }//class

class SecondRectangle{ public int area(int l, int b){ int sarea = l*b; System.out.println("Required Area::"+sarea); return sarea; }//method }//class

public class MyShape{ public void combinedArea(FirstRectangle r,SecondRectangle sr){ r.rectArea(10,5); sr.area(15,10); }//method public static void main(String []s){ FirstRectangle r = new FirstRectangle(); SecondRectangle sr = new SecondRectangle(); MyShape m = new MyShape(); m.combinedArea(r,sr); }//main }//class

I want to add the area both rectangles and display them, but not getting how to do that. Please help me.

Hi Friend,

Here is your required code:

class FirstRectangle{
     public int rectArea(int l,int b){
         int farea = l*b;
         System.out.println("Required Area::"+farea);
         return farea; 
         }
}

class SecondRectangle{
    public int area(int l, int b){
        int sarea = l*b; 
        System.out.println("Required Area::"+sarea); 
        return sarea; 
        }
}


public class MyShape{
    public void combinedArea(FirstRectangle r,SecondRectangle sr){
        int area1=r.rectArea(10,5); 
        int area2=sr.area(15,10); 
        int sum=area1+area2;
        System.out.println("Combined Area is: "+sum);
        }
        public static void main(String []s){
            FirstRectangle r = new FirstRectangle();
            SecondRectangle sr = new SecondRectangle();
            MyShape m = new MyShape();
            m.combinedArea(r,sr); 
        }
}

Thanks

Thanks for the solution. Now its working.

One more thing I need to ask: Is there any provision by which I can directly use farea and sarea for calculating the sum. I mean say the respective calculated values are stored in farea and sarea. Can't I use them directly?
