Basically scale method is not overrided Because it has different parameters in
both classes.............
 
The rule is that in polymorphism if a method is overrided then the child class
method is invoked........ and if a method exist in parent class and not
overrided in child class then the parent class method is invoked...........
2ndly in polymorphism if a method exist in child and not exist in parent then
there is an compile time error............. ok

hi,

i think that is because you use different parameters in scale methods.

at s.scale(1), 1 is thought as integer not long. change long to int. it will
resolve

Hi Gurus,

Could you pls explain me why the following code is printing "Scale Shape"
instead of "Scale Circle"

class Circle extends Shape
{

public void scale(int x)
{
System.out.println( "Scale Circle");
}

public static void main(String args[])
{
Shape s = new Circle();
s.scale(1);
}

}

class Shape
{
public void scale(long x)
{
System.out.println( "Scale Shape");
}
}

Regards

Chooti Baba
