出于某种原因，当我将其作为方法或通常包含在 if 语句中时，我的加载"circle"将无法正常工作。有人知道为什么吗？

Question

这是我的测试程序的代码。我有所有的代码来避免运行时或语法错误，但我不知道这是否是一个逻辑错误

import java.util.Scanner;
public class Test {
static void Load() throws InterruptedException {
System.out.print("r-");
Thread.sleep(300);
System.out.print("r\");
Thread.sleep(300);
System.out.print("r|");
Thread.sleep(300);
System.out.print("r/");
Thread.sleep(300);
System.out.print("r-");
Thread.sleep(300);
System.out.print("r\");
Thread.sleep(300);
System.out.print("r|");
Thread.sleep(300);
System.out.print("r/");
Thread.sleep(300);
System.out.print("r-");
Thread.sleep(300);
System.out.print("r\");
Thread.sleep(300);
System.out.print("r|");
Thread.sleep(300);
System.out.print("r/");
Thread.sleep(300);
System.out.print("r-");
Thread.sleep(300);
System.out.print("r\");
Thread.sleep(300);
System.out.print("r|");
Thread.sleep(300);
System.out.print("r/");
Thread.sleep(300);
System.out.print("r-");
Thread.sleep(300);

System.out.print("r\");
Thread.sleep(300);
System.out.print("r|");
Thread.sleep(300);
System.out.print("r/r");
Thread.sleep(300);
}
public static void main(String[] args) 
throws InterruptedException {
// declaring variables
String user1 = "";
int password;
String passyn;
String account;
String user2 = "";
boolean isRunning = true;
String tryAgain = "";
int new1Password = 0;
int new2Password;
// my code
while (isRunning) {
Scanner sc = new Scanner(System.in);
Load();
System.out.println("rWelcome to LOGIN");
System.out.print("Enter your name(If you don't have an account, type none): ");
user1 = sc.next();
if (user1.equals("Dov")) {
System.out.print("Enter your password: ");
password = sc.nextInt();
if (password == 1234) {
Load();
System.out.println("rACCESS GRANTED");
System.out.printf("Welcome %s", user1);
isRunning = false;
} else {
System.out.print("ACCESS DENIED");
}
}
// end of loop
else if (user1.equals("None") || user1.equals("none")) {
System.out.print("Do you have an account: ");
passyn = sc.nextLine();
if (passyn.equals("No") || passyn.equals("no")) {
System.out.print("Type yes to sign up: ");
account = sc.next();
if (account.equals("No") || account.equals("No")) {
} else {
System.out.print("What is your new username: ");
user2 = sc.nextLine();
System.out.print("What is your password(Numbers only!!): ");
new1Password = sc.nextInt();
System.out.print("Would you like to return to the login screen: ");
tryAgain = sc.next();
if (tryAgain.equals("no") || tryAgain.equals("No")) {
isRunning = false;
}
}
}
} else if (user1.equals(user2)) {
System.out.print("What is your password: ");
new2Password = sc.nextInt();
if (new1Password == new2Password) {
Load();
System.out.println("rACCESS GRANTED");
System.out.printf("Welcome %s", user1);
isRunning = false;
} else {
System.out.println("ACCESS DENIED");
}
} else {
isRunning = false;
}
}
}
}

它作为一个循环持续运行，直到ACCESS GRANTED。这个程序运行得很好，但我的加载系统从来没有运行过。我在一个不同的程序中运行它，也作为一种方法，它运行得很好。我把它插入到Test.java程序中，什么也没发生。有什么想法吗？(我的IDE使用replit.com(

正如user9594794在评论中提到的那样，代码对我来说也很好。

我唯一的建议是：

1. 重新设定加载方法：

   char[] sequence = {'-', '\', '|', '/', '-', '\', '|', '/'};
   int n = 3; // or however many times you want the spinning text
   for (int i = 1; i < n; i++) {
   for (char c : sequence) {
   System.out.print("r" + c);
   Thread.sleep(300);
   }
   }
   

2. 仔细查看循环和条件，并可能对它们进行重构。评论"；循环结束"；与循环的实际结束不一致。确实，循环在该点之后可能不再有任何迭代(用户Dov和密码1234(，但情况可能并非如此。
