Password V2


Objetive:

Write a java program to ask the user for their login and password (both must be integer numbers) until the entered login is "12" and the password is "1234". The user will have a maximum of three attempts.


Code:

import java.util.*;
public class Main
{
	public static void main(String[] args)
	{
		int user, pass;
		int counter = 0;

		do
		{
			System.out.print("Enter a user:  ");
			user = Integer.parseInt(new Scanner(System.in).nextLine());

			System.out.print("Enter a password:  ");
			pass = Integer.parseInt(new Scanner(System.in).nextLine());

			if ((user != 12) || (pass != 1234))
			{
				System.out.println("Login Error");
				counter++;
			}

		} while (((user != 12) || (pass != 1234)) && (counter != 3));

		if ((user != 12) || (pass != 1234))
		{
			System.out.println("Logged out!");
		}
		else
		{
			System.out.println("Login successful");
		}
	}
}
