Java is most popular programming language for developing software and web applications. Java is generally a popular choice among developers, with millions of Java programmes today. Java is a multi-platform, object-oriented, network-centric programming language that may be used as a standalone platform. Join JAVA Training in Chennai at FITA Academy to learn all the basic concepts.

Object-Oriented Programming Model:

Abstraction:

Abstraction refers to concealing internal intricacies and expressing things in simple words. Consider the addition of two integers. The method's internal functioning is hidden from the outside world. Object-oriented programming has numerous methods for achieving abstraction, such as encapsulation and inheritance. A Java programme is another excellent example of abstraction. Java handles the conversion of simple statements to machine language and conceals the deep implementation complexities from the outside world.

Encapsulation:

In object-oriented programming, encapsulation is a technique for implementing abstraction. Encapsulation is used to limit access to class members and methods. In object-oriented programming, access modifier keywords are used for encapsulation. In Java, for example, encapsulation is accomplished by using private, protected, and public keywords.

Polymorphism:

Polymorphism refers to the concept of a thing acting differently in different conditions. Polymorphism is divided into two types: compile-time polymorphism and runtime polymorphism. Method overloading is used to achieve compile-time polymorphism.

Inheritance:

Inheritance is a concept in object-oriented programming in which one object is based on another. The mechanism of code reuse is inheritance. The inherited object is known as the superclass, and the object that inherits the superclass is known as the subclass. To implement inheritance in Java, we use the extends keyword. 

Association:

The OOPS notion of association is used to define the relationship between objects. The association defines the assortment of items. Teachers and students, for example. A teacher and students have a one-to-many relationship. A student can also have a one-to-many relationship with teacher items. However, the student and teacher objects are distinct from one another.

Composition:

The composition is a subset of aggregation. The composition is a more limited type of aggregation. It is a case of composition when the enclosed object in a "HAS-A" connection cannot exist independently.
