Abstract class is a class that can have both abstract and non-abstract methods, while interface is a contract that defines methods that a class must implement.
Abstract class can have constructors, fields, and methods, while interface can only have abstract methods.
A class can implement multiple interfaces but can only inherit from one abstract class.
Abstract classes are used when some common functionality needs to...
DI stands for Dependency Injection and IOC stands for Inversion of Control.
DI is a design pattern where the dependencies of a class are injected from the outside rather than created within the class itself.
IOC is a design principle where the control of object creation and flow is inverted from the class to an external entity.
DI helps in making classes more modular, testable, and flexible.
IOC helps in decoupling co...
