Question

x.Hmritten these three classes forcalculating the Speed Of Sound. I would like to know how to stop the menu from repeatedly showing up. In my DialogInput Class (getMenuItem method) I tried to replace "continue;" with "break;" but it won't let me compile. Any input would be great. Thank you!



Hereare the class and two objects:

public class SpeedOfSound   //class to calculate speed of sound(fps) in a medium
{
    private double distance;
    private String medium;
    private double time;
   
    public SpeedOfSound()   //no arg constructor
    {
        distance = 0;
    }
   
    public void setDistance(double distance)
    {
        this.distance = distance;
    }
   
   
    public double getSpeed(String medium)
    {
        if (medium.startsWith("A")){    
            return distance/1100;       //returns time sound travels in Air
        } // Class method?
        else if (medium.startsWith("W")){  
            return distance/4900;        //returns time sound travels in Water
        }
        else {
            return distance/16400; }    //returns time sound travels in Steel
        }

   
    public String toString()
    {
        return "Distance =" + distance;
    }
}
       
           
   
   

import javax.swing.*;

public class DialogInput
{
    public String getMenuItem(String title, String...items)
    {
        String menu = "";
       
        for(int i = 0; i<items.length; i++){
            menu += items[i] + " ";
        }
        menu += "Enter Selection";
       
        while(true)
        {
       
       
            String medium = JOptionPane.showInputDialog(menu);
            if(medium==null||medium.equals("")){
                continue;
            }
                for(int k=0; k<items.length;k++)
                {
                if(medium.equalsIgnoreCase(items[k]))
                    return medium;
                }
               
               

            }
           
        }
     
     
      public double getDouble(String prompt)
      {
         while(true)
         {
         try
         {
             String input = JOptionPane.showInputDialog(prompt);
             if(input==null||input.equals("")){
                 return Double.MIN_VALUE;
                }
                 return Double.parseDouble(input);
                }
                 catch(NumberFormatException e)
                 {
                 }
          }
       }
      
    }

import javax.swing.*;
import java.text.DecimalFormat;

public class SpeedOfSoundApp
{
    public static void main(String [] args)
    {
        DecimalFormat d = new DecimalFormat("###,###,###,##0.00");
        DecimalFormat t = new DecimalFormat("###,###,##0.0000000");
        DialogInput input = new DialogInput();
        String medium = input.getMenuItem("Medium Menu", "Air", "Water",
        "Steel");
       
        double distance = input.getDouble("Enter distance (ex. 5280): ");
        SpeedOfSound sos = new SpeedOfSound();
        sos.setDistance(distance);
       
        double time = sos.getSpeed(medium);
       
        JOptionPane.showMessageDialog(null,
        "In " + medium + ", sound travels " +
