Wie bringt man einen Code zurück zum Hauptmenü?

Question

Ich habe ein Programm in Java erstellt, das versucht, ein Popup-Menü zu erstellen, das Ihnen Auswahlmöglichkeiten bietet.

Ich habe die Auswahl und wie alles funktioniert, aber ich kann nicht scheinen, es so zu bekommen, wenn Sie Ihren Benutzernamen und Ihr Passwort erstellen, bringt Sie zurück zum Hauptmenü.

Alles für das?

import javax.swing.*; 

public class MyOwn { 

    /** 
    * @author Noah 
    */ 
    public static void main(String[] args) { 
     Object[] options = { 
      "Create Login", 
      "Login", 
      "Quit" 
     }; 
     int menuOption = JOptionPane.showOptionDialog(null, "Please choose the " + "program you would like to run:", "Program Menu", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, options, options[2]); 
     boolean exit = false; 
     while (!exit) { 
      switch (menuOption) { 
      case 0: 

       String userName = JOptionPane.showInputDialog(null, "Create a username:", "johndoe"); 
       String password = JOptionPane.showInputDialog(null, "Create a password:", "johndoe123"); 
       exit = true; 
       break; 
      case 1: 
       String userNameEntry = JOptionPane.showInputDialog(null, "Enter your username:"); 
       String passwordEntry = JOptionPane.showInputDialog(null, "Enter your password:"); 
       if (userName.equals(userNameEntry) && password.equals(passwordEntry)) { 

        Object[] optionsTwo = { 
         "Season Quiz", 
         "Profile Analysis", 
         "Piggy Bank" 
        }; 
        int menuOptionTwo = JOptionPane.showOptionDialog(null, "Please choose the " + "program you would like to run:", "Program Menu", JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE, null, optionsTwo, optionsTwo[2]); 
        switch (menuOptionTwo) { 
        case 0: 
         System.out.println("Season Quiz"); 
         break; 
        case 1: 
         System.out.println("Profile Analysis"); 
         break; 
        case 2: 
         System.out.println("Piggy Banks"); 
         break; 
        } 
       } 
       break; 
      case 2: 
       System.exit(0); 
      default: 
       break; 
      } 
     } 
    } 
} 

Irgendwelche Vorschläge bitte?

Ich weiß nicht, ob ich dich richtig verstanden habe. Ich zeige das Hauptmenü nach dem Erstellen des Benutzernamens und des Passworts und ich zeige es nach dem Login wieder.

Object[] options = {"Create Login", "Login", "Quit"}; 
JOptionPane optionPane = new JOptionPane(); 

int menuOption = showMenu(options); 
boolean exit = false; 
String userName = null; 
String password = null; 
while(!exit){ 
    switch (menuOption) { 
     case 0: 

      userName = JOptionPane.showInputDialog(null,"Create a username:","johndoe"); 
      password = JOptionPane.showInputDialog(null,"Create a password:","johndoe123"); 
      menuOption = showMenu(options);//Show MainMenu again 
      break; 
     case 1: 
      String userNameEntry = JOptionPane.showInputDialog(null,"Enter your username:"); 
      String passwordEntry = JOptionPane.showInputDialog(null,"Enter your password:"); 
      if(userName == null || password == null){ 
       System.err.println("userName or password not set"); 
       exit = true; 
       break; 
      } 
      if (userName.equals(userNameEntry) && password.equals(passwordEntry)) { 

       Object[] optionsTwo = {"Season Quiz", "Profile Analysis", "Piggy Bank"}; 
       int menuOptionTwo = showMenu(optionsTwo);//Show SpecialMenu 
       switch (menuOptionTwo) { 
        case 0: 
         System.out.println("Season Quiz"); 
         break; 
        case 1: 
         System.out.println("Profile Analysis"); 
         break; 
        case 2: 
         System.out.println("Piggy Banks"); 
         break; 
       } 
       menuOption = showMenu(options);//Show MainMenu 
      } 
      break; 
     case 2: 
      exit = true; 
      System.exit(0); 
     default: 
      break; 
    } 
} 

und hier die showMenu -Methode

private static int showMenu(Object[] options) { 
    return JOptionPane.showOptionDialog(null, "Please choose the " 
        + "program you would like to run:","Program Menu",JOptionPane.YES_NO_CANCEL_OPTION, 
      JOptionPane.QUESTION_MESSAGE,null,options,options[2]); 
}
