Q1. What is difference between interface and abstract class
Ans. 
Interface is a contract with no implementation, while abstract class can have some implementation.
• Interface cannot have any implementation, only method signatures

• Abstract class can have both abstract methods and concrete methods

• A class can implement multiple interfaces but can only inherit from one abstract class

• Interfaces are used to achieve multiple inheritance in Java
