- Single Level inheritance – A class inherits properties from a single class.
- Multilevel inheritance – A class inherits properties from a class which again has inherits properties.
- Hierarchical inheritance – Multiple classes inherits properties from a single class.

What is inheritance in OOP?
Inheritance in OOP = When a class derives from another class. The child class will inherit all the public and protected properties and methods from the parent class. In addition, it can have its own properties and methods. An inherited class is defined by using the extends keyword.
What is inheritance in OOP Java?
Inheritance is an important pillar of OOP(Object-Oriented Programming). It is the mechanism in java by which one class is allowed to inherit the features(fields and methods) of another class.
What is polymorphism in OOPs?
Polymorphism is one of the core concepts of object-oriented programming (OOP) and describes situations in which something occurs in several different forms. In computer science, it describes the concept that you can access objects of different types through the same interface.
What is polymorphism in Java?
In Java, polymorphism refers to the ability of a class to provide different implementations of a method, depending on the type of object that is passed to the method. To put it simply, polymorphism in Java allows us to perform the same action in many different ways.
What is overloading in OOPs?
Method overloading is a salient feature in Object-Oriented Programming (OOP). It lets you declare the same method multiple times with different argument lists.
What is abstraction in OOPs?
In object-oriented programming, abstraction is one of three central principles (along with encapsulation and inheritance). Through the process of abstraction, a programmer hides all but the relevant data about an object in order to reduce complexity and increase efficiency.
What is OOPs in Java?
What is OOPs in java? OOps in java is to improve code readability and reusability by defining a Java program efficiently. The main principles of object-oriented programming are abstraction, encapsulation, inheritance, and polymorphism. These concepts aim to implement real-world entities in programs.
What is OOPs concept?
Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behavior.
What is polymorphism in oops?
What is abstraction in OOP?
What is Abstraction in OOP? Abstraction is the concept of object-oriented programming that “shows” only essential attributes and “hides” unnecessary information. The main purpose of abstraction is hiding the unnecessary details from the users.
What are the two types of polymorphism?
Types of Polymorphism
- Subtype polymorphism (Runtime) Subtype polymorphism is the most common kind of polymorphism.
- Parametric polymorphism (Overloading)
- Ad hoc polymorphism (Compile-time)
- Coercion polymorphism (Casting)
