OOP Concepts has become an important part of software development. Writing Programs using Top down approach of traditional structured programming or Functional Programming method becomes difficult as the complexity of the program increases. This is where Object-oriented programming has its upper hand.
OOP Concepts allow you to break these complex programs into small bites, which you can solve one by one. OOP is an effective model that allows your program to grow without becoming impossible to maintain. Add to it ubiquity of languages like Java and OOP Principles become need of the hour.
OOP is a whole new way to address problems. Here you create a class, instead of writing a program, which has variables and functions.
Objects are self-contained examples of that class and you have a control where you can make them interact with each other in many ways. This kind of encapsulation makes knowledge of Object-oriented Programming and its main Principles a must if you are serious about working on big projects and developing software for mobiles.
There are many important features of Object-Oriented programming, however, before proceeding further we suggest you read Learn 7 Basics of Java Programming to Start Coding Today which helps you to know all the basic concepts of Java.
Discussion in this blog is divided into following structure:
Object Oriented programming Concepts in Java.
OOP Best practices.
Advantages of Java OOP concepts.
Differences between object oriented and object-based program.
Let us dive right into main Principles of object-oriented programming and discuss them with relevant examples.
What are OOP concepts?
Object oriented programming is a method based on the concepts of “objects” which contains data and methods. Its main objective is to bring flexibility in programming while building small and large software applications. Most of the programming language like Java, C++, Python, C#, etc. follow OOP concepts.
