JAVA

programming language

Object Oriented

Object-oriented means we organize our software as a combination of different types of objects that incorporates both data and behavior.
Features

Platform Independent

Java code can be run on multiple platforms, for example, Windows, Linux, Sun Solaris, Mac/OS, etc. Java code is compiled by the compiler and converted into bytecode.

Java OOP Concept

Object-Oriented Programming is a paradigm that provides many concepts, such as inheritance, data binding, polymorphism, etc.

Object & Class

An entity that has state and behavior is known as an object.A class is a group of objects which have common properties.

Constructors

In Java, a constructor is a block of codes similar to the method. It is called when an instance of the class is created.

Inheritance

Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object.

Encapsulation

Encapsulation in Java is a process of wrapping code and data together into a single unit, for example, a capsule which is mixed of several medicines.

Polymorphism

If a class has multiple methods having same name but different in parameters, it is known as Method Overloading.If subclass (child class) has the same method as declared in the parent class, it is known as method overriding in Java.

Abstract

A class which is declared with the abstract keyword is known as an abstract class in Java. It can have abstract and non-abstract methods (method with the body).

Interface

The interface in Java is a mechanism to achieve abstraction. There can be only abstract methods in the Java interface, not method body. It is used to achieve abstraction and multiple inheritance in Java.

String

In Java, string is basically an object that represents sequence of char values. An array of characters works same as Java string.
