constructors??

[srikanth reddy]

 Which of the following statements are true
1) constructors cannot be overloaded
2) constructors cannot be overridden
3) a constructor can return a primitive or an object reference
4) constructor invocation occurs from the current class up the hierarchy to the ancestor class

here why the answer cannot be 4,...
since when u are creating the child class object ..its constructor is invoked..which calls the superclass const...i agree that if there are any println statements..superclass's println is executed...and then subclass...
but what does invocation mean here??? dont u think the option is generalised..

thanks

invocation means that you are calling the code inorder to execute the code. Constructors do indeed call the constructors of their parent classes before excuting their own constructor. so all the constructors in the ancestor classes are called before before the current object constructor.
