Can you explain polymorphism?

Can you explain polymorphism?

Literally, polymorphism means "having multiple forms". In programming, if a variable can hold more than one type of value, then that's a kind of polymorphism. If functions can process more than one type of parameter, that's also polymorphism.

Why do we use polymorphism?

The good reason for why Polymorphism is need in java is because the concept is extensively used in implementing inheritance.It plays an important role in allowing objects having different internal structures to share the same external interface. polymorphism as stated clear by itself, a one which mapped for many.

What is polymorphism and example?

The word polymorphism means having many forms. … Real life example of polymorphism: A person at the same time can have different characteristic. Like a man at the same time is a father, a husband, an employee. So the same person posses different behaviour in different situations. This is called polymorphism.

Why is polymorphism important in OOP?

Polymorphism is the ability of different objects to receive the same message and respond in different ways. Polymorphism simplifies the communication between objects by using a common interface to hide different implementation details.

What is OOPs concept?

OOP concepts in Java are the main ideas behind Java's Object Oriented Programming. They are an abstraction, encapsulation, inheritance, and polymorphism. … Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security.

What is encapsulation OOP?

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.

What is the types of inheritance?

Single Inheritance. … Hierarchical Inheritance. Multilevel Inheritance. Hybrid Inheritance (also known as Virtual Inheritance)

What is the purpose of inheritance?

The primary purpose of inheritance is to reuse code from an existing class. Inheritance allows you to create a new class that starts off by including all data and implementation details of the base class. You can then extend the derived class, to add data or behavior.

What is data hiding in OOPs?

Data hiding is a software development technique specifically used in object-oriented programming (OOP) to hide internal object details (data members). Data hiding ensures exclusive data access to class members and protects object integrity by preventing unintended or intended changes.

How does polymorphism work?

Polymorphism is the concept of a function or an object having more than one form or implementation. The main use of polymorphism in Object Oriented Programming is the ability of objects of different types to respond to the same method call, implementing a specific type of behavior.

What is abstraction with 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.

What is encapsulation with example?

Encapsulation in Java is a process of wrapping code and data together into a single unit, for example, a capsule which is mixed of several medicines. … Now we can use setter and getter methods to set and get the data in it. The Java Bean class is the example of a fully encapsulated class.

WHAT IS interface in OOP?

Interfaces in Object Oriented Programming Languages. An interface is a programming structure/syntax that allows the computer to enforce certain properties on an object (class).

What is the real time example of polymorphism?

Method overloading is an example of static polymorphism, while method overriding is an example of dynamic polymorphism. 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.

What is inheritance in OOP?

Inheritance is a mechanism in which one class acquires the property of another class. For example, a child inherits the traits of his/her parents. With inheritance, we can reuse the fields and methods of the existing class. Hence, inheritance facilitates Reusability and is an important concept of OOPs.

What is the difference between abstraction and polymorphism?

2) Another difference between Polymorphism and Abstraction is that Abstraction is implemented using abstract class and interface in Java while Polymorphism is supported by overloading and overriding in Java. … That's all about the difference between Abstraction and Polymorphism in Java.

Is inheritance possible in C?

There is no Compiler-level support for inheritance in C. Nevertheless, as others have already pointed out, Object Oriented coding does not REQUIRE such support. However, its a lot easier to write OO code in C++. C is not an Object Oriented language.
