Oops Concepts In Java

What is Oops Concepts?

The full form of OOP is object-oriented programming.  Oop is a class of programming languages that are built on objects.  

In object-oriented programming, more attention is paid to the processed data and not the logic of the process.  

The aims of object-oriented programming are that it implements real-world entities such as inheritance, hiding, polymorphism, etc.




Oops Concepts and Terminology

Class

In Oops concepts, a class is a specification of an object. Class is a user-defined data type.  Or we can say that class is a blueprint of an object.

Object

In Oops concepts an object is an instance of a class.  An object is a runtime entity in oops concepts.  The program object is related to real world object.  An object takes up space in memory.

Encapsulation

Wrapping data and methods to a single unit class is called encapsulation.  This data is not accessible by hiding the outside code data.  If understood in simple language, then adding data and function together is called encapsulation.

Abstraction

Abstraction means to test a problem in many ways.  Abstraction selects such object which is required by the program.

Polymorphism

Polymorphism is made up of two words, one is poly means Many and the other is morphism means Forms.  Polymorphism means doing one thing in two different ways.

Inheritance

Using the properties of one class in another class is inheritance.  Inheritance is used by accessing the properties of the object of the derived class, the object of the base class.


Benefit of Oops Concepts

Security

Due to the encapsulation in Oops concepts, it is also very secure for security purposes.

Reusability

By using inheritance in Oops concepts, you can use the features of an existing class in a new class.

Effective Communication

Due to the message passing technique in Oops concepts, it is very simple to do effective communication in it.

Developing Complex Software

With the help of Oops concepts, anyone can develop any kind of complex software.

Easily Upgraded

It is very easy to upgrade an object-oriented system in any small and large system.

Easy Partition of Work

Due to being based on Oops concepts object, any complicated work is easy to partition.

Maintenance

The same goes for maintaining object-oriented code as well.

Efficiency

Oops, concepts provide better efficiency and an easy development process.


Application of Oops Concepts

  • It has a real-time system.

  •  It consists of an object-oriented database.

  •  It consists of artificial intelligence and expert systems.

  •  It has a graphic user interface that is designed in the windows operating system.

  •  It provides a client-server system.

  •  It consists of neural networks and parallel programming.

What is Oops Programming?

 As we have told you above, oops means object-oriented programming, means a programming technique, or can also be called programming.  Oops, concepts are also called a paradigm of programming.  Oops, concept programming has both data and function.  In Oops concepts programming, programming is done according to the real world entity, in which an object can be made a relation with another object.  Through this programming cameos in procedural programming have been removed.  Programming languages ​​like java, c++, python, c#, and PHP are used in Opp's programming, out of which java is used the most in the present time.


What is Procedural Programming?


 You heard a word above whose name was procedural programming, what is it after all?  Do you know if not, then we tell you what happens to it?  Procedural programming means, it is a programming paradigm, in which the instructions of the program are written according to a sequence.  In which all the instructions in a program are executed in one line.  In a Procedural program, the entire game is of function, which is also called structural language.  The reason is that procedural programming is used in many languages.


Need of oops concepts

The need for Oops concepts is very high in high-level languages ​​such as COBALL, FORTRAN, and C. The program written in it is called a procedure printed program.

 In this type of programming, the program to be done is also seen in the form of tasks, which increases its need.

 And many functions are written to do the work to be done from the program of these programming.

 Global data is used in this so that the same data can be used in many programs and it does not have to be written again and again.

 This is supposed to allow the data in any of the rectangles to be changed independently by an external function at any time.

 Problems in object-oriented programming can be divided into entities called objects.

Problem Solving Methodology and Techniques

What is   Algorithm  ? The algorithm is defined as the step-by-step solving of a problem in the user's language.   It is considered an effective procedure for solving a problem with an infinite number of steps.  The characteristics of the algorithm are,  Precise  Unambiguous  Finite termination  Unique solution Once the algorithm is written, it can be coded into a problem using any programming language.  The algorithm uses 3 different constructs Sequence: sequence says that instructions are to be executed in what order or sequence. Branching or decision making: Branching involves testing or condition and based on the outcome of the condition testing different instruments are executed. Repetition: Repetition means one or more instructions shall be repeated several times.  This is otherwise called a loop.  There are different types of loops such as,  do-while, for What is    Pseudocode ? It is a concise descri...

What is Internet how does it Work ?

The Internet today is an amazing technology that knows everything. If the internet was not there, it would not have been as fast as the world is moving today. In today's time, everyone uses the internet and why should everything become so easy with the help of the internet.  But not as much as the Internet is beneficial, but it is also harmful. So if you also use the Internet, then you should know about the Internet.  That is why I have done this article for all of you so that everyone can understand the internet in a very easy and simple language. So let's know with complete information about the internet. What is the internet? The internet is that the largest network within the world, connecting many computers.  A network may be a group of two or more computer systems linked together. The internet is a wire that is in the sea around the world.  And this wire keeps information and data moving around the world. This data can be anything like text, mp3, document, imag...

What is a Data Structure and its Types ?

If you also like to read computer-related information or if you are a computer science student, then this post can be beneficial for you.  In this article, I have explained what is a data structure?  How many types of data are there?  And many more.  To understand the data structure, we need to know what is data.  So let's know about the data and its structure. What is Data ? Data is any row fact or value are called data. Value can be anything if there is any value like 1,2,3,4,5,6 all these have value means it is data.   If we talk about the second example, then a book is also data because it is a book, and the book has value.  Meaning that even the thing which has some value is called data. What is Information ? Information is processing data.  Meaning that if any data is on process mode then we can call that data information.   For example, if we talk about an example, I told you that "you come to me", so the one who told me is ...
