Help with sorting two types:

[twcast]

Need help sorting a string and a double.
Here is current code:

First part:

import javax.swing.*;
public class Item
{
        final int NUM_ITEMS = 5;
        String listItem;
        double price;

      
        public void Item(String listItem, double price)
        {
        }

      
        public String getListItem()
        {
                return listItem;
        }
        public double getPrice()
        {
                return price;   
        }
        public void setListItem(String oneListItem)
        {
                listItem = oneListItem;
        }       
        public void setPrice(double onePrice)
        {
                price = onePrice;
        }
}

Second Part

import javax.swing.*;
import java.util.*;
public class driver
{
        public static void main(String[]args)
        {
                char choice;
                String[] listItem = {"Coffee", "Cappuccino", "Hot Chocolate", "Bagel", "Donut"};
                double[] price =        {1.00,   2.00,     1.50,                         1.25,     .75};
                
                choice = JOptionPane.showInputDialog(null,"To view menu by item name, enter n \n To view by price enter p",
                        "Menu Viewer", JOptionPane.QUESTION_MESSAGE); 

                if(choice.equalsIgnoreCase("n")||choice.equalsIgnoreCase("p"))
                        {
                        switch(choice)
                                {
                                case 'n':  
                                        sortName (listItem, price);
                                        break;
                                case 'p': 
                                        sortPrice(listItem,price);
                                        break;
                                default:
                                        JOptionPane.showMessageDialog(null,"Invalid entry, Please try again");
                                        break;
                                }
                        }
        
                         
        }
        
        public static void sortPrice(String[] listItem, double[] price)
        {
                Arrays.sort(price);     
                for(int count=0;count<=4;++count)
                        System.out.println(listItem[count]+"  "+price[count]);
        }

        public static void sortName(String[] listItem,double[] price)
        {
                Arrays.sort(listItem);
                
                for(int count=0;count<=4; ++count)
                 System.out.println(listItem[count]+"  "+ price[count]);
        }

}

Any suggestions would be great!

What are you hoping to achieve with this?

        public void Item(String listItem, double price)
        {
        }

You know that this is not a constructor since it has a void return type, and even if it were, all it would do would be prevent you from using a default constructor and only allow use of a non-functioning parameter-requiring constructor.

Much better would be

        public Item(String listItem, double price)
        {
           this.listItem = listItem;
           this.price = price;
        }

This may seem like nitpicking, but these details are very important.

Next, if you are going to do sorting, look at having Item implement a Comparable<Item> interface.

edit: next, in your driver class (it should be Driver, by the way), where do you ever use your Item class???

You need to be able to sort the Item object. For this you need to understand the Compare interface and how Comparators work.

Check out this posting for a simple example.

When you understand the above solution, for a more complex solution but also a reusable solution you can also check out a Bean Comparator.
