java - 如何停止方法不断循环

Question

我目前正在尝试用java完成一个包含多个类的程序，该程序将允许用户输入信息来帮助他或她预订摇滚音乐节的门票、住宿、 parking 等。我已经从“适应”类之一开始，将用户的正确输入返回到主类，但是，我发现当我运行程序并输入选项 3 时，它立即连续循环，我必须终止它。我在网上搜索了一种停止循环的方法，并让它返回正确的输入信息，但无济于事，在这个循环让我发疯之前，我将不胜感激对一个非常新的新手的任何帮助!下面是我的主要类(class)和“住宿”类(class)。预先感谢您，并对我的任何困惑编码表示歉意，因为我一直在尝试各种选择，正如我之前所说的。

import java.util.Scanner;
import java.util.InputMismatchException;

public class clydeRockfest {

public static void main(String[] args) {




    boolean quit = false;
    Scanner in = new Scanner(System.in);
    int choice;    // Display the menu
    int answer = 0;

    Accommodation accommodation = new Accommodation();
    //accommodation.getaccommodation();


    do{

    System.out.println("1\t Festgoers");
    System.out.println("2\t Ticket");
    System.out.println("3\t Accommodation");
    System.out.println("4\t Transport");
    System.out.println("5\t Parking");
    System.out.println("0\t Quit");


    System.out.println("Please enter your choice:");

    //Get user's choice
    choice=in.nextInt();
     if(choice == 0)
         quit=true;


    //Display the title of the chosen module
    switch (choice) {

   break;

        case 3: accommodation.getaccommodation();
            System.out.println("You require " + answer + " accommodation."); 
   break;


        case 0: 
            quit=true;
   break;

        default: System.out.println("Invalid choice, please choose again.");

    } //end of switch
} //end of the main method
    while(!quit);
} //end of class

}

public class Accommodation {

     private String accommodation;

     void getaccommodation(){


        int no = 0;   // no accommodation at all required
        int self_Pitch = 0;  // chosen if requiring a pitch
        int tent = 0;  // chosen if using a tent
        int answer = 0;
        int choice = 0;

        boolean done = false;


        System.out.println("Do you require accommodation?");
        System.out.println();

        // Answer validation loop
        boolean validanswer = true;
        while (!validanswer){   

        System.out.println("Enter:(1=NO, 2=SELF-PITCH, 3=TENT)");
        System.out.println();


        if(answer > 0 && answer < 4){
            validanswer = true;
            done = true;
        }// ends if
        else{
        System.out.println();
        System.out.println("That is not a valid answer, please choose again:");
        System.out.println();

        }   // ends else
    } //ends while
}

        public void setaccommodation(String accommodation){
        this.accommodation = accommodation;
       }

输出:

Please enter your choice:

Do you require accommodation?

You require 0 accommodation.
1    Festgoers
2    Ticket
3    Accommodation
4    Transport
5    Parking
0    Quit
Please enter your choice:

Answer 1

您可以通过设置 done=false 来启动循环，但不要设置 done = true，这样循环就永远不会结束
