Method overloading and overriding are two concepts in object-oriented programming that allow methods to have multiple implementations.

• Method overloading is when multiple methods have the same name but different parameters.

• Method overriding is when a subclass provides a specific implementation of a method that is already provided by its parent class.

• Overloading is resolved at compile-time while overriding is resolved at runtime.

• Overloading is used to provide different ways of ...read more

• Interface is a collection of abstract methods and constants

• Abstraction allows for easier maintenance and modification of code

• Interface allows for multiple inheritance in Java

• Abstraction and interface are both used to achieve abstraction in programming

Factory Pattern is a creational design pattern that provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.

• Factory Pattern is used to create objects without specifying the exact class of object that will be created.

• It promotes loose coupling by separating object creation from the rest of the code.

• Commonly used in situations where a class can't anticipate the class of objects it must create.

• Examples i...read more
