Thread: Creating new objects within methods

I want to make a program where users are prompted to enter a username and a password and have these two values create a new instance of the Object User. But I'm not sure where to start. Can anyone point me in the right direction?

import java.util.Scanner;
 
 
public class Main {
	public static void main(String[] args) {
		createUser();
 
	}
	public class User
	{
		String username;
		String password;
	}
	public static void createUser()
	{
		String username;
		String password;
		Scanner getPassword = new Scanner(System.in);
		Scanner getUsername = new Scanner(System.in);
		System.out.println("Set a username.");
		username = getUsername.nextLine();
		System.out.println("Set a password.");
		password = getPassword.nextLine();
		System.out.println(username + " " + password);
 
	}
 
}

I'm just not sure how to take username + password and put it into an object.

How about prompting the user in main to enter in a username and password. Then use the username and password in the constructor of the object you create.

example

enter in username
//user enters in name
enter in password
//user enters in password

object = new object(username, password)

Thats what I posted in the OP lol.
I just don't know how to take the user input and enter it into a method that creates the object and assigns the object a name like User1, then the next created user to be named User2 etc.

ArrayList<blah> t = new ArrayList<blah>();
 
	t.add(new blah(/*the username , the password*/));

You could put it in a loop for as many times as you want.

I'm sorry man I don't have a solid foundation in programming or Java, so I'm not even sure what you posted.
Tell me if this is right or wrong.
Where you have blah, my array values will be? Or will User go there?

"blah" in my case is the data type. In your case it would be User. You might want to put User in another class instead of having it in main.

public class User
	{
		String username;
		String password;
 
         public User(){
              createUser();
          }
	public void createUser()
	{
		Scanner getInfo = new Scanner(System.in);
		System.out.println("Set a username.");
		username = getInfo.nextLine();
		System.out.println("Set a password.");
		password = getInfo.nextLine();
		System.out.println(username + " " + password);
 
	}
}

This is how your User class should look. Took out a few redundant things and this should be in another class file (separate from Main). Makes it easier to keep neat and clean.
