What is polymorphism example?
An important example of polymorphism is how a parent class refers to a child class object.
In fact, any object that satisfies more than one IS-A relationship is polymorphic in nature.
For instance, let’s consider a class Animal and let Cat be a subclass of Animal .
So, any cat IS animal..
What is the use of encapsulation?
Overview. Encapsulation is one of the fundamentals of OOP (object-oriented programming). It refers to the bundling of data with the methods that operate on that data. Encapsulation is used to hide the values or state of a structured data object inside a class, preventing unauthorized parties’ direct access to them.
How do you implement encapsulation?
How to implement encapsulation in java: 1) Make the instance variables private so that they cannot be accessed directly from outside the class. You can only set and get values of these variables through the methods of the class. 2) Have getter and setter methods in the class to set and get the values of the fields.

What is encapsulation in oops with example?
Encapsulation is an Object Oriented Programming concept that binds together the data and functions that manipulate the data, and that keeps both safe from outside interference and misuse. The best example of encapsulation could be a calculator. …
What do you mean by encapsulation?
In object-oriented programming (OOP), encapsulation refers to the bundling of data with the methods that operate on that data, or the restricting of direct access to some of an object’s components.
What is abstraction example?
Abstraction means displaying only essential information and hiding the details. Data abstraction refers to providing only essential information about the data to the outside world, hiding the background details or implementation. Consider a real life example of a man driving a car. … This is what abstraction is.
What is the difference between abstraction and encapsulation?
Abstraction is the method of hiding the unwanted information. Whereas encapsulation is a method to hide the data in a single entity or unit along with a method to protect information from outside. … In abstraction, implementation complexities are hidden using abstract classes and interfaces.
What is abstraction and encapsulation give real life example?
Both abstraction and encapsulation are underlying foundations of object oriented thought and design. So, in our cell phone example. The notion of a smart phone is an abstraction, within which certain features and services are encapsulated. The iPhone and Galaxy are further abstractions of the higher level abstraction.
Is abstraction and data hiding same?
Abstraction shows the relevant information and rejects the non-essential details. On the other hand, data hiding is used to hide the data from the parts of the program. … Abstraction is used in class to create a new user-defined datatype. As against, in classes data hiding is used to make the data private.
Can we achieve abstraction without encapsulation?
Encapsulation is definitely possible without inheritance. … Abstraction and Polymorphism, however, are directly related to inheritance. Abstraction is when you take away the implementation details of an object and create an abstract class or an interface (speaking in terms of Java).
What is encapsulation in OOPs?
Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). It describes the idea of bundling data and methods that work on that data within one unit, e.g., a class in Java. This concept is also often used to hide the internal representation, or state, of an object from the outside.
