Ques 1

Explain the 'diamond problem' and how Java solves it.

The 'diamond problem' occurs in multiple inheritance when a class inherits from two classes that have a common ancestor. In Java, this is avoided by allowing a class to implement multiple interfaces.

Ques 2

Explain the concept of method hiding in Java.

Method hiding occurs when a subclass provides a static method with the same signature as a static method in its superclass. It does not override the superclass method.

Example:

class Parent { static void display() { /* method implementation */ } }
class Child extends Parent { static void display() { /* hiding method implementation */ } }
