This program accepts a username and password and then outputs a response if they are accepted or not.
My Code
import java.util.Scanner;
public class Usernames {
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
System.out.print("Type your username: "); // Input username
String userName = reader.nextLine();
System.out.print("Type your password: ");
String passWord = reader.nextLine();
if (userName.equals("alex") && passWord.equals("mightyducks")) {
System.out.println("You are now logged into the system!");
} else if (userName.equals("emily") && passWord.equals("cat")) {
System.out.println("You are now logged into the system!");
} else {
System.out.println("Your username or password was invalid!");
}
}
}
Model Code
import java.util.Scanner;
public class Usernames {
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
System.out.print("Type your username: ");
String username = reader.nextLine();
System.out.print("Type your password: ");
String password = reader.nextLine();
// NOTE: This solution would be quite ugly should there be more users.
// In the following weeks we'll see how to do this better.
if ((username.equals("alex") && password.equals("mightyducks")) ||
(username.equals("emily") && password.equals("cat"))) {
System.out.println("You are now logged into the system!");
} else {
System.out.println("Your username or password was invalid!");
}
}
}
Comments
My solution is fairly close to theirs except they have placed all the usernames and passwords on one line whereas I have separated them into if else statements. That does save some repetition though.
