关于字符串检查的IFN语句中的java不可访问代码
出于某种原因,我得到了一个错误,即行currentUser = gar.getAccount(userN);
是不可访问的,但它不应该是Garage.getAccount()
只是从Hashmap
检索。两个if语句都没有相互对抗,我也尝试过添加else语句,但不管它说什么,这行都是无法到达的
package main;
import java.util.Scanner;
public class Main {
private static Scanner input;
private static Garage gar;
private static Attendant currentUser;
private static boolean isManager;
public static void main(String[] args) {
input = new Scanner(System.in);
gar = new Garage(10, 80, 10);
currentUser = null;
while (currentUser == null)
logIn();
}
public static void logIn() {
System.out.println("Enter username: ");
String userN = input.nextLine();
System.out.println("Enter password:");
String userP = input.nextLine();
//if no username, go back
if(gar.getAccount(userN) == null) {
error("Incorrect username");
return;
}
if(gar.getAccount(userN).getPassword().equals(userP) == false); { //if entered password doesn't match
error("Incorrect password");
return;
}
currentUser = gar.getAccount(userN);
return;
}
//update to throw error pop-up later
public static void error(String er) { System.out.println(er); }
}

您的语法不正确,if语句的条件不应以分号结尾
