我试着用这个代码：

Scanner username = new Scanner(System.in);
System.out.println("Hello " + username.nextLine() + ", please authenticate using your password:");
Scanner password = new Scanner(System.in);
String pw = "test";
String pwEnter = password.nextLine();
if (pw != pwEnter) {
System.out.println("Sorry, you don't have access to the System.");
} else {
System.out.println("Thank you for authenticating, you can proceed with:");
}
}
}
