Help sorting arrays

[MKunstman]

Ok so I have this program almost done...just stuck on the sort. I can get the array to sort by name, but the prices do not follow. I want the product prices that are 0-4 to remain with their products 0-4, right order when read into the array. Just cannot seem to get it. I want to sort by name or price as you can see by the code. I am sure its something very simple that I am missing but I cannot put my finger on it.

import javax.swing.*;
import java.util.*;
public class CoffeeDriver
{
	public static void main(String[] args)
	{
		String[] itemSold = new String[5];
			itemSold[0] = "Coffee";
			itemSold[1] = "Water";
			itemSold[2] = "Milk";
			itemSold[3] = "Bagel";
			itemSold[4] = "Donut";
		double[] itemCost = new double[5];
			itemCost[0] = 1.00;
			itemCost[1] = 2.00;
			itemCost[2] = 1.50;
			itemCost[3] = 1.25;
			itemCost[4] = 0.75;
		
		char choice;
		choice = JOptionPane.showInputDialog(null, "Welcome to Wings Coffee Shop." + "\nWe have a great list of items on our menu." + "\nWould you like to see our menu sorted by name or price? (n/p):").charAt(0);
		choice = Character.toLowerCase(choice);
		switch(choice)
			{
			case 'n':
				methodSortName(itemSold, itemCost);
				break;
			case 'p':
				sortPrice(itemSold, itemCost);
				break;
			default:
				JOptionPane.showMessageDialog(null, "Entry must be n for name or p for price." + "\nPlease try again.");
				break;
			}
	}
	public static void methodSortName(String itemSold[], double itemCost[])
	{
		Arrays.sort(itemSold);
		int size = itemSold.length;
		String display = "Item      Price\n";
		for(int x = 0; x < size; ++x)
		{
			display += itemSold[x] + "      " + itemCost[x] + "\n";
		}
		JOptionPane.showMessageDialog(null, display);
	}
	public static void sortPrice(String[] itemSold, double[] itemCost)
	{
		Arrays.sort(itemCost);
		int size = itemCost.length;
		String display = "Item      Price\n";
		for(int x = 0; x < size; ++x)
		{
			display += itemSold[x] + "      " + itemCost[x] + "\n";
		}
		JOptionPane.showMessageDialog(null, display);
	}
}

You can use a map to keep your Items bound to their prices.
