What is Constructor in Java Tutorial Part 14.1 | Lecture

Constructors in java

Constructor in java is a special type of method that is used to initialize the object.
It is a block of code which is invoked and executed at the time of Object creation.

Name of constructor must be same as name of Class.
Constructor also can not have any return type
It constructs the values i.e. provides data for the object that is why it is known as constructor.
Constructor in Java can not be abstract, static, final or synchronized. These modifiers are not allowed for constructor.

How compiler understand that how much memory needed for a object ???Is it depend upon how you define your constructor???

[monalikajain]

hey...can we create constructor and methods both in same class?

[anchalrana]

sir, i want to ask that why the name of the constructor is same as class name, why there is no return type with constructor and why it is automatically called?

[blacktenshu]

Thanks for the simple explanation. For some reason my textbook likes to complicate simple concepts.

[natetolbert]

curious...
I see the advantages of using the naming convention. However, I'm wondering if it is possible (even if unreasonable) to override it. For example, is it possible to define a constructor with:

class A {

public constructor(){
}
}

for example, and then create an A object with something like:

A a = new (A.constructor())
