Why do we write the class name twice while creating object in java, like Vehicle bugatti = new Vehicle.

Question

I want to know what does these two class name means, one before the object name and then after new keyword. (JAVA)

Answer 1

The second class name which is after new keyword, is actually a constructor name which is there in the program by default.

I hope you understand

Answer 2

Firstly to declare the type and secondly to invoke the constructor.

Answer 3

The left side i.e, Vehicle bugatti means create a object called bugatti of type Vehicle, like same as "int i" or "String s".

The right side i.e, new Vehicle(); is to store everything the class Vehicle has in the object bugatti like same as "8, 10" or "Science is Cool".

Answer 4

The constructor have to have the same name like the class.

So you have a class and inside a constructor:

public class MyClass{

//constructor
public MyClass(){

}

}

And when you create an object you normally call the constructor via new.

new MyClass() calls the constructor, which returns an instance of MyClass.

In your example bugatti is a variable from type Vehicle. The constructor returns an instance of Vehicle which is assigned o bugatti.
