Constructor in java? How it is Different From Methods Java? [#2023]

Java is a programming language that enables developers to create robust, high-performance applications. Java is platform-independent, meaning that it can be run on any type of hardware or operating system.

Java applications are also portable, meaning they can be easily moved from one platform to another. Java is used in a wide range of applications, including mobile apps, web-based applications, and enterprise systems. Java is a powerful programming language with a rich set of features. Java enables developers to create sophisticated applications with ease.

In Java, a constructor is a block of code that’s executed when an instance of an object is created. A constructor is similar to a method, but a few key differences set them apart:

– A constructor doesn’t have a return type.

– The name of the constructor must be the same as the name of the class.

– A constructor is called when an instance of an object is created. It’s not called directly by developers.

Methods are different than constructors in several ways:

-A method has a return type (void, int, String, etc.) whereas a constructor does not.

-The name of a method can be anything, while the name of a constructor must be the same as the name of the class.

-A method is called by developers, while a constructor is called when an instance of an object is created.

So basically, constructors are used to initializing objects, and methods are used to perform operations on objects.

Types of Constructors in Java

There are two types of constructors in Java: the default constructor and the parameterized constructor.

default constructor

The default constructor is a constructor that takes no parameters. It is automatically generated by the compiler if you don’t write your own constructor for a class. If you do write your own constructor, the default constructor is no longer generated by the compiler.

parameterized constructor

The parameterized constructor is a constructor that takes parameters. It allows you to initialize an object with specific values when you create it.
