Is it true that constructor returns an object?

Question

class Test{
  public Test(){
    System.out.println("I am here");
    return;// not getting error
  }

  public static void main(String[] args){
    Test test = new Test();
  }
}

I am java beginner. My tutor told me that constructor returns an object and showed me the above example. is it really happening because method is not returning any value but the return;is not getting an error.

Answer 1

No, a constructor initialises an object that's already been created. It doesn't return an object. Your tutor is wrong.

You don't need to write return; inside a constructor, unless you're returning before the end of the code.

Answer 2

this line of code

return;

dose not mean return value but it just end the execution of contractor and since it's in the last line so it's not necessarily

situation where you use return in constructor

class Test
{

  private int a;
  public Test(int a)
  {
    System.out.println("I am here");
    if(a>10)
    {
        System.out.println("I'm Executed but not the rest of code");
        return;
    }
    System.out.println("I'm the last line of constructor"); 
  }

  ...

}

return in constructor its just like return in void method

Answer 3

No. The role of constructor is to initialize the state of the object.

new keyword is responsible to create an object in the heap. In below example, using new keyword you are creating an object and then you are pointing that object with type Test variable name test.

 Test test = new Test();

Answer 4

No, that is not true at all

A constructor in Java is a block of code similar to a method that’s called when an instance of an object is created. Here are the key differences between a constructor and a method:

• A constructor doesn’t have a return type.

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

• Unlike methods, constructors are not considered members of a class.

• A constructor is called automatically when a new instance of an object is created.

Example:

class Bike1{  
    Bike1(){
        System.out.println("Bike is created");
    }  

    public static void main(String args[]){  
        Bike1 b=new Bike1();  
    }  
}
