Junior Developer Trainee Interview Questions and Answers for Freshers

Runtime polymorphism is the ability of an object to take on multiple forms during runtime.

• It is achieved through method overriding and inheritance.

• The decision of which method to call is made at runtime based on the object's actual type.

• It allows for more flexible and dynamic code.

• Example: Animal class with different subclasses like Dog, Cat, etc. Each subclass can have its own implementation of the same method like makeSound().
