我有点问题。我正在尝试使用菜单制作服务器。Evrythink 还可以，但是当我启动服务器时它就卡住了。我的想法是有菜单，并用它来启动服务器：命令：“启动服务器”并启动。但是当我启动它时，我可以摆脱这个循环。这是我的代码。如何在“启动服务器”后返回主菜单？

import java.util.Scanner;
import server.DB.DataBase;
import server.LoadSettings;
public class MeetingsServer {
private static server.ServerCore serverCore = null;
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
LoadSettings loadSettings = LoadSettings.Init();
System.out.println("Use 'help' command to list all commands");
while (input.hasNext()) {
String command = input.nextLine();
switch (command) {
case "start server":
System.out.println("Starting server ....");
serverCore = new server.ServerCore();
serverCore.start();
break;
case "status server":
serverCore.statusServer();
break;
case "set config":
loadSettings.writeDatacondig();
break;
case "reload config":
loadSettings.loadDataConfig();
System.out.println("Configuration was reseted");
break;
case "view config":
loadSettings.viewConfig();
break;

System.out.println("Configuration from file");
loadSettings.viewConfigFile();
