调用一个方法从交换机返回一个不同的int

Question

我想调用一个方法并基于输入，将该值返回给我在另一个类中的交换机。因此，如果我要选择数组中的“1”元素，我会将答复作为“4”返回到其他类中，并使其运行开关“4”。

在另一个类中，我将开关“4”设置为另一种方法。但是，我一直从我的方法返回int值“1”，因为它一直在调用该方法（开关“1”）。这是有道理的，因为它是我的数组中的“1”元素，它应该运行开关“1”，但我认为通过设置“reply = 4”，它会返回一个int“4”到我的另一个类中，开关“4”。

如何让我的方法返回我想要的值，以便将其放入我的开关中？

这里就是我做的打电话给我的第一类：

package bunnyhunt; 

import javax.swing.ImageIcon; 
import javax.swing.JOptionPane; 

public class Messages { 

//Objects 
public Rooms roomCall = new Rooms(); 

//Instance Variables 
public static boolean gameOver = false; 
public static int roomNum; 
public static int reply; 
boolean visitedOtherRoom = false; 

//Constructors  
//Methods  
public void start() { 

//while loop 
    while (gameOver == false) { 

//do-while loop 
     do { 
      String[] parkEntrance = {"Spring Meadow", "Aeryn's Overlook", "Garden Gate"}; 
      reply = JOptionPane.showOptionDialog(null, "You're at the Park Entrance! What do you want to do?", "Bunny Adventure", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, parkEntrance, parkEntrance[0]); 

      switch (reply) { 
       case 0: 
        System.out.println("oh man...Spring"); 
        visitedOtherRoom = true; 
        roomCall.springMeadow(); 

        break; 
       case 1: 
        System.out.println("oh man...Aeryn"); 
        visitedOtherRoom = true; 
        roomCall.aerynsOverlook(); 

        break; 

       case 2: 
        System.out.println("oh man...Garden"); 
        visitedOtherRoom = true; 
        roomCall.gardenGate(); 

        break; 

       default: 
        System.out.println("error"); 

      } 

     } while (visitedOtherRoom == false); 

     switch (reply) { 
      case 0: 
       System.out.println("second 0!!!"); 
       visitedOtherRoom = true; 
       roomCall.parkEntrance(); 

       break; 
      case 1: 
       visitedOtherRoom = true; 
       System.out.println("yes man!"); 
       roomCall.aerynsOverlook(); 
       break; 

      case 2: 
       visitedOtherRoom = true; 
       roomCall.gardenGate(); 

       break; 

      case 3: 
       visitedOtherRoom = true; 
       roomCall.peacefulPond(); 

       break; 

      case 4: 
       visitedOtherRoom = true; 
       roomCall.readingNook(); 

       break; 
      default: 
       System.out.println("default"); 

     } 
    } 

    JOptionPane.showMessageDialog(null, 
      "Game Over!!!"); 
} 

} 

和我的第二个，我所说的东西存在：

package bunnyhunt; 

import javax.swing.JOptionPane; 


public class Rooms { 


public static int reply; 

public int springMeadow() { 

    String[] springMeadow = {"Park Entrance", "Reading Nook",     "Search"}; 
    Messages.reply = JOptionPane.showOptionDialog(null, "You're in the Spring Meadow! What do you want to do?", "Spring Meadow", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, springMeadow, springMeadow[0]); 

    switch (reply) { 
     case 0: 

      reply = 0; 

      break; 
     case 1: 

      reply = 4; 
      break; 

     case 2: 

      JOptionPane.showMessageDialog(null, 
        "You searched!"); 

      break; 

     default: 
      System.out.println("error"); 

    } 


    return reply; 

} 

public int aerynsOverlook() { 
String[] aerynsOverlook = {"Park Entrance", "Peaceful Pond", "Search"}; 
    Messages.reply = JOptionPane.showOptionDialog(null, "You're in Aeryn's Overlook! What do you want to do?", "Aeryn's Overlook", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, aerynsOverlook, aerynsOverlook[0]); 

    return reply; 

} 

public int gardenGate() { 

    String[] gardenGate = {"Park Entrance", "Rose Gardent", "Butterfly Garden", "Flowering Forest"}; 
    return reply; 

} 

public int readingNook() { 

    String[] readingNook = {"Spring Meadow", "Search"}; 
    Messages.reply = JOptionPane.showOptionDialog(null, "You're in the Reading Nook! What do you want to do?", "Reading Nook", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, readingNook, readingNook[0]); 
    return reply; 

} 

public int parkEntrance() { 

    String[] parkEntrance = {"Spring Meadow", "Aeryn's Overlook", "Search"}; 
    Messages.reply = JOptionPane.showOptionDialog(null, "You're in the Park Entrance! What do you want to do?", "Park Entrance", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, parkEntrance, parkEntrance[0]); 
    return reply; 
} 

public int peacefulPond() { 

    String[] peacefulPond = {"Raven's Tower", "Aeryn's Overlook", "Search"}; 
    Messages.reply = JOptionPane.showOptionDialog(null, "You're in the Peaceful Pond! What do you want to do?", "Peaceful Pond", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, peacefulPond, peacefulPond[0]); 
    return reply; 
} 

} 

Answer 1

你是不是从start()返回reply值方法，因为这种方法是无效的，并且switch里面的语句不会返回任何东西，尽管它们包含调用适当的方法，如int aerynsOverlook(). You should modify开始`像这样的方法：

​​

其次，我不明白你是如何调用start()方法来获得它的返回值并在第二个开关中使用它。您的MEssages类与Rooms
