How to code a very simple login system with java

Question

I am a new programmer and I want to implement a simple login page for a project I am doing. Can someone help me with this?

Answer 1

You can try like this:

import java.util.Scanner;

public class Login {

public void run() {

    Scanner scan = new Scanner (new File("Filecontainingcredentials.extension"));

    Scanner userInput = new Scanner (System.in);

    String user = scan.nextLine();

    String pass = scan.nextLine(); 

    String inputUser = userInput.nextLine();

    String inputPass = userInput.nextLine();

    if (inputUser.equals(user) && inputPass.equals(pass)) {

        System.out.print("Login successful");

    } else {

        System.out.print("Login error");

    }

}

}

Beware of where you use it, it is not that secure, it just gives you an idea of how the login system works.
