when the super class constructor is executed which draw method is called? I was expecting superclass's draw() to be called but that wasn't the case

Why would draw() in Shape class be called. The draw method in RoundShape class overrides the draw method of shape class so the call will be polymorphic...

Ankit is it because at run time the jvm decides which draw method to call based on the object?

Bang on target, that's right, the call will be decided based on the actual object
