How do constructors work?

A Constructor is a block of code that initializes a newly created object . A Method is a collection of statements which returns a value upon its execution. A Constructor can be used to initialize an object.

There are two rules defined for the constructor.

In class-based object-oriented programming, a constructor (abbreviation: ctor) is a special type of subroutine called to create an object . It prepares the new object for use, often accepting arguments that the constructor uses to set required member variables.

The purpose of constructor is to initialize the object of a class while the purpose of a method is to perform a task by executing java code. Constructors cannot be abstract, final, static and synchronised while methods can be. Constructors do not have return types while methods do.

Constructors are special class functions which performs initialization of every object . The Compiler calls the Constructor whenever an object is created. Constructors initialize values to object members after storage is allocated to the object. Whereas, Destructor on the other hand is used to destroy the class object.
