Question

When creating a method inside a class if you use the parameter:

public String Method(ClassName NewObject){}

or in my example below:

public String EqualsTo(Deck aCard){}

will it create a new object of that class within that method? If not anyone mind explaing what I is happening with that parameter?

NOTE: Disregard any minor syntax errors as I just constructed this to get my question across better so this is not a complete class.

import java.util.Scanner;
import java.util.Random;

public class Deck {
private int suit;
private int rank;
private Random generator = new Random();
Scanner in = new Scanner(System.in);

    //Default constructor
    public Deck() {
    suit = suit.random(4);
    rank = rank.random(13);
    }


public String EqualsTo(Deck aCard){}
}

Answer 1

Objects are created when you use the new keyword. On the other hand, when you declare a method as

public String EqualsTo(Deck aCard){}

it says that the EqualsTo() method takes a Deck reference as a parameter. In order to use the method, you need to create a Deck object and keep a reference to it. Then you send the reference to the method.
