Software Technical Trainer Interview Questions and Answers

Abstraction is the concept of hiding complex implementation details and showing only the necessary features of an object.

• Abstraction allows us to focus on what an object does rather than how it does it

• It helps in reducing complexity and improving efficiency

• Examples include abstract classes and interfaces in object-oriented programming

Polymorphism is the ability of a single function or method to operate on different types of data.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.
