Basic Concepts in Object Oriented Programming. Raul Ramos / IT User .. Any OO Programming Language tutorial usually includes a OO overview: Java, C++. In this page, we will learn about the basics of OOPs. Object-Oriented Programming is a paradigm that provides many concepts such as inheritance, data binding. The core of the pure object-oriented programming is to create an object, in code, This is a very important concept of object-oriented programming since this.

An Object contains both the data and the function, which operates on the data. For example - chair, bike, marker, pen, table, car, etc.

OOPS Concepts in Java with Examples

It offers robust and natural mechanism for organizing and structure of any software. For example, in English, the verb run has a different meaning if you use it with a laptop, a foot race, and business.

Here, we understand the meaning of run based on the other words used along with it. The same also applied to Polymorphism.

It is a technique of creating a new data type that is suited for a specific application. For example, while driving a car, you do not have to be concerned with its internal working.

C++ Object Oriented

Here you just need to concern about parts like steering wheel, Gears, accelerator, etc. In this OOPS concept, the variables of a class are always hidden from other classes. It can only be accessed using the methods of their current class. For example - in school, a student cannot exist without a class. It defines the diversity between objects. In this OOP concept, all object have their separate lifecycle, and there is no owner.

For example, many students can associate with one teacher while one student can also associate with multiple teachers. It is also called "death" relationship. Child objects do not have their lifecycle so when parent object deletes all child object will also delete automatically. Any house can have several rooms. So, if you delete the house room will also be deleted.

Objects created for Object-Oriented Programs can be reused in other programs. In this OOPS concept, the variables of a class are always hidden from other classes.

Object Oriented Programming – Java OOPs Concepts With Examples

It can only be accessed using the methods of their current class. For example - in school, a student cannot exist without a class. It defines the diversity between objects.

In this OOP concept, all object have their separate lifecycle, and there is no owner. For example, many students can associate with one teacher while one student can also associate with multiple teachers. It is also called "death" relationship.

Child objects do not have their lifecycle so when parent object deletes all child object will also delete automatically. Any house can have several rooms. So, if you delete the house room will also be deleted.

Advantages of OOPS: OOP offers easy to understand and a clear modular structure for programs. Objects created for Object-Oriented Programs can be reused in other programs. Thus it saves significant development cost. Large programs are difficult to write, but if the development and designing team follow OOPS concept then they can better design with minimum flaws. It also enhances program modularity because every object exists independently.

Programming languages can be classified into 3 primary types Unstructured Programming Languages: The most primitive of all programming languages having sequentially flow of control.

Code is repeated through out the program Structured Programming Languages: Has non-sequentially flow of control. Use of functions allows for re-use of code.

Object Oriented Programming: Click here if the video is not accessible. Let's understand these 3 types with an example. Suppose you want to create a Banking Software with functions like Deposit Withdraw Show Balance Unstructured Programming Languages The earliest of all programming language were unstructured programming language.

Structured Programming With the arrival of Structured programming repeated lines on the code were put into structures such as functions or methods. Whenever needed, a simple call to the function is made.

Object-Oriented Programming In our program, we are dealing with data or performing specific operations on the data. In fact, having data and performing certain operation on that data is very basic characteristic in any software program.

What is OOPS?

Experts in Software Programming thought of combining the Data and Operations. The same code in OOPS will have same data and some action performed on that data. What is JavaScript?Blockchain Go Programming Reviews. It is only an logical component and not the physical entity.

For example, consider a class Complex with public functions as getReal and getImag.

Accept Learn more. Objects created for Object-Oriented Programs can be reused in other programs.

Manipulating these objects to get results is the goal of Object Oriented Programming.
