Pa check naman po at pa tama po ayan pong nasa picture yung gagawin po at eto yung code kopo. Ang tanong kopo is pano kopo idadagdag jan yung square at operation class po na sinasabi. Thank you po.

class Operation{
int square(int n){
return n*n;
}
}

class Circle{
Operation op;//aggregation
double pi=3.14;

double area(int radius){
op=new Operation();
int rsquare=op.square(radius);//code reusability (i.e. delegates the method call).
return pi*rsquare;
}



public static void main(String args[]){
Circle c=new Circle();
double result=c.area(5);
System.out.println(result);
}
}
