Need help filling in the code with JAVA, ONLY update between the bolded parts and do not change anything else.

import java.awt.Color; import java.util.TreeMap; import java.util.Map; import java.util.Set; import java.util.Iterator; /** This program is an example from Chapter 16 in Big Java. It demonstrates a map that maps names to colors. Expected output: Adam : java.awt.Color[r=255,g=0,b=0] Eve : java.awt.Color[r=0,g=0,b=255] Juliet : java.awt.Color[r=0,g=0,b=255] Romeo : java.awt.Color[r=0,g=255,b=0] ------------------------------- Adam : java.awt.Color[r=255,g=0,b=0] Eve : java.awt.Color[r=0,g=0,b=255] Juliet : java.awt.Color[r=0,g=0,b=255] Romeo : java.awt.Color[r=0,g=255,b=0] */ public class MapDemo { public static void main(String[] args) { Map favoriteColors = new TreeMap(); favoriteColors.put("Juliet", Color.BLUE); favoriteColors.put("Romeo", Color.GREEN); favoriteColors.put("Adam", Color.RED); favoriteColors.put("Eve", Color.BLUE); // Print all keys and values in the map Set keySet = favoriteColors.keySet(); for (String key : keySet) { Color value = favoriteColors.get(key); System.out.println(key + " : " + value); } System.out.println("-------------------------------") ;  //-----------Start below here. To do: approximate lines of code = 5 // 1. make an iterator for keySet //2. while the iterator has more elements //get the next element, which is a key of map favoriteColors //get the corresponding value //print the key value pair, as above }//closing brace of while //-----------------End here. Please do not remove this comment. Reminder: no changes outside the todo regions. } }
