我的主要方法是开关盒菜单，这是工作良好。如果用户选择2，它将转到该类并正常返回，但如果用户选择1，它将执行该方法，但随后暂停并不返回。我错过了什么？如果我做了一个系统退出它退出，但我需要它返回到菜单。
停止的方法结束：

for (int index = 0; index < items.length; index++) {
            System.setOut(console);
            System.out.printf("%-16s %16d %16d %16d %16s \n", items[index], supplyOnHand[index], last24HourUsage[index], daysOnHand[index], status[index]);
            System.setOut(o);
            System.out.printf("%-16s %16d %16d %16d %16s \n", items[index], supplyOnHand[index], last24HourUsage[index], daysOnHand[index], status[index]);
        }
    }
}

主要内容：

import java.io.IOException;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) throws IOException {
        boolean exit = false;
        do {
            System.out.println("Please enter your choice:");
            System.out.println("1. Enter new data.");
            System.out.println("2. Review latest data.");
            System.out.println("3. Exit.");
            Scanner sc1 = new Scanner(System.in);
            int choice = sc1.nextInt();
            switch (choice){
                case 1:
                    Dashboard.main();
                    break;
                case 2:
                    ReadFile.main();
                    break;
                case 3:
                    exit = true;
                    break;
            }
        } while (!exit);
    }
}

编辑，希望能让它更清楚。我不擅长措辞。如果我选择2，它将执行并返回菜单：

Please enter your choice:
1. Enter new data.
2. Review latest data.
3. Exit.
2
Please enter your choice:
1. Enter new data.
2. Review latest data.
3. Exit.

如果我选择1，它不会返回，只是挂起：

Please enter your choice:
1. Enter new data.
2. Review latest data.
3. Exit.
