What is object oriented programming easy explanation?
Object Oriented programming (OOP) is a programming paradigm that relies on the concept of classes and objects. It is used to structure a software program into simple, reusable pieces of code blueprints (usually called classes), which are used to create individual instances of objects.
What are four basic principles of object oriented programming?
Object-oriented programming has four basic concepts: encapsulation, abstraction, inheritance, and polymorphism.
How do you explain polymorphism to a child?
Polymorphism is the ability of an object to take on many forms. Any Java object that can pass more than one IS-A test is considered to be polymorphic— tutorialspoint. This means any child class object can take any form of a class in its parent hierarchy and of course itself as well.
What is object in OOP with example?
An object in OOPS is nothing but a self-contained component which consists of methods and properties to make a particular type of data useful. For example color name, table, bag, barking. When you send a message to an object, you are asking the object to invoke or execute one of its methods as defined in the class.
How do you explain oops to an interview?
In an interview , when you are asked explain OOP concepts, just do not list them out. Tell one at a time and then explain what it means. Do not stop there . Be creative and give a real world example to illustrate the concept and then explain how to implement it using a language you know .
What is OOP polymorphism?
Polymorphism is the method in an object-oriented programming language that performs different things as per the object’s class, which calls it. With Polymorphism, a message is sent to multiple class objects, and every object responds appropriately according to the properties of the class.
What are objects in oops?
In object-oriented programming (OOP), objects are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process. Each object is an instance of a particular class or subclass with the class’s own methods or procedures and data variables.
