Question

We know how to create an instance by writing in the main…

Class newObject = new Class();

Is there a way to create a ‘newObject’ by user’s input something and pops a new newObject? I was thinking using the Scanner but i am not sure how it could be done. I was guessing like this:

Scanner sc = new Scanner(System.in);
Class sc.next(); = new Class();

or like this?

Scanner sc = new Scanner(System.in);
(some name) = sc.next();
Class (some name) = new Class();

So the user inputs an object name (some name) into the scanner and that object name (some name) will be created.

Thank you very much in advance!

Answer 1

The best way would be to make a constructor that takes in a Scanner class to create Class, given that you have access to the Class code and can put in the value.

Class testClass{

  testClass(Scanner input)
  {
    //Populate the class.
  }

}

If Class is a primitive, then you could just use the nextInt (Or other related) type functions.
