Q2. What is run-time polymorphism? what is SQL and RDBMS? What is the concept of inheritance and real time examples? code for a program to reverse a string
Ans. 
Run-time polymorphism is the ability of a method to do different things based on the object it is acting upon.
• Run-time polymorphism is achieved through method overriding in Java.

• It allows a subclass to provide a specific implementation of a method that is already provided by its superclass.

• Example: Animal class has a method 'makeSound'. Dog and Cat classes can override this method to make different sounds.
