i know went wrong , if question has been asked million times if direct me 1 of posts has been solved great since can't seem find 1 that's problem.

import javax.swing.*;  import java.util.scanner;  public class userid {  public static void main(string[] args) {      scanner input = new scanner(system.in);      string username;     string password;     string email;     string scanner1;      username = "username";     password = "password";     email = "emailhere";      system.out.println("------------------------------------------");     system.out.println("welcome id memory tester");     system.out.println("author: me");     system.out.println("------------------------------------------");      system.out.println("what username?");       scanner1 = (input.nextline());       if (scanner1 == username) {         system.out.println("correct, username!");     } else {         system.out.println("incorrect, not username!");     } } 

}

== operator compares references.

you need use .equals().

change to

   if (scanner1.equals(username)) {        system.out.println("correct, username!");    } else {        system.out.println("incorrect, not username!");    }
