**喂 我开始学习java了, 我写了这段代码&当我写admin时它会继续循环!
。 。 **
import java.util.Scanner;
public class Don1 {
public static void main(String[] args) {
String in_user, in_pass;
do {
Scanner user = new Scanner(System.in);
System.out.println(" Please Login :\n Username :");
in_user = user.nextLine();
/*
* Scanner pass = new Scanner(System.in); System.out.println(
* " Please Login :\n Password :"); in_pass = pass.nextLine();
*/
}
while (in_user != "admin");
System.out.println("1- Student Operation\n 2- Staff Operations \n 3- Admin Operations");
System.out.println(in_user);
}
}
,这是控制台流程:
Please Login : Username : w Please Login : Username : admin Please Login : Username :
不知道错误在哪里:(
