- Why do we need OOPS Concepts in Java?
Object-Oriented Programming and System (OOPS) ideas in Java serve to minimize code complexity and facilitate code reuse. Programmers prefer dealing with real-world items or objects. In object-oriented programming, data and methods are merged into a single unit known as an object. Object-oriented programming and Systems offer higher comprehension, adaptability, and code maintenance over time.
Sun Microsystems first published Java in 1995. It is a quick, secure, and dependable programming language. Since then, its reach and functionality have grown significantly. The most recent Java version has numerous innovations that improve the efficiency, stability, and security of Java applications.
What are the OOPS Concepts in Java?
1. Objects & Classes
Objects are the fundamental unit of OOPS, representing real-world entities. They are invoked using methods. These methods are declared In Java courses in Pune, a class object is typically created using a new keyword.
A class is a predefined or user-defined template used to build objects. It shows the characteristics and capabilities shared by all objects of the same class. It provides many features, such as interfaces, class bodies, class names, and access modifiers.
2. Abstraction
Abstraction entails presenting only the important facts to the end user while suppressing irrelevant aspects that serve as a distraction. For instance, when using an ATM, we only respond to a series of questions to finish the transaction without comprehending the context between the bank and the ATM.
3. Encapsulation
The technique of classifying data variables and procedures is known as encapsulation. Access to these items is then restricted to class objects only. This is referred to as “data hiding” and is done to safeguard data.
4. Inheritance – Single, Multilevel, Hierarchical, and Multiple
The procedure by which one class acquires the traits and skills of another is called inheritance. Inheritance’s primary role is to enable code reuse. All each subclass has to do is specify its characteristics. The remaining features can be extracted straight from the parent class.
Single Inheritance – A parent-child connection in which the child class expands the parent class’s features. Class Y extends Class X.
Multilevel Inheritance –A parent-child relationship known as “multilevel inheritance” occurs when one child’s class overlaps with another’s. Classes X and Y are extended. Class Z builds upon Class Y.
Hierarchical Inheritance – In this parent-child relationship, a single class is extended by several child classes. Class Z extends Class X, while Class Y does the same.
Multiple Inheritance – Describes a parent-child relationship in which two or more parent classes extend into one child class. This inheritance is not supported by Java.

Applications
Databases with object-oriented design
These systems use Object-Oriented Database Management Systems (OODBMS) in place of RDBMS. Strings and integers are not stored in these databases.
Design of Real-time Systems
Because of their complexity, these systems are incredibly challenging to develop and construct from the ground up. These integrated complicated frameworks can be handled and constructed with the use of object-oriented approaches.
Simulation and Modelling –
Comprehending and accurately modeling interactions is essential for complex modeling systems. An alternate and straightforward technique for simulating similar processes is offered by object-oriented approaches.
Systems for Office Automation
It covers any electronic information sharing methods that involve message exchanges between humans and robots, whether they are formal, casual, personal, or business-related.
Advantage of OOPs over Procedure-oriented programming language
Compared to procedural programming, object-oriented programming (OOP) has the following significant advantages:
OOP encourages the reuse of code:
You may make reusable components with objects and classes, which reduces duplication and improves development efficiency.
OOP improves the structuring of code:
It gives the code a logical and understandable structure that facilitates debugging, maintenance, and comprehension.
The DRY (Don’t Repeat Yourself) philosophy is supported by OOP:
By reducing code repetition, this idea promotes cleaner, easier-to-maintain code.
OOP facilitates quicker development:
OOP makes it possible to construct applications more quickly and effectively by reusing existing code and generating modular components.
