Q1. Tell about Oops concepts
Ans. 
OOPs concepts are fundamental principles in object-oriented programming, including inheritance, encapsulation, polymorphism, and abstraction.
• Inheritance: Allows a class to inherit properties and behavior from another class. Example: class Dog extends Animal.

• Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: private variables and public methods.

• Polymorphism: Ability to present...read more

Q2. Difference between method overloading and method overriding
Ans. 
Method overloading is having multiple methods in the same class with the same name but different parameters. Method overriding is having a method in a subclass with the same name and parameters as a method in its superclass.
• Method overloading is resolved at compile time based on the method signature, while method overriding is resolved at runtime based on the object type.

• Method overloading is used to provide different ...read more

Q3. What is sigleton class ?
Ans. 
A singleton class is a class that can only have one instance created and provides a global point of access to that instance.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundles data and methods into a single unit, protecting data from outside interference.

• Polymorphism: Allows objects to be treated as instances of their parent class, enabling flexibility in code.

• Promotes loose coupling between components

• Improves code reusability and maintainability

• Examples: Constructor injection, Setter injection, Interface injection
