I want a solution using the Netbeans editor.

I want the code written and the output

A Map Example public static void main(String args[]) { Map map = new HashMap(); map.put("one","1st"); map.put("second", new Integer(2)); map.put("third","3rd"); map.put("third", "III"); Set set1 = map.keySet(); Collection collection = map.values(); Set set2 = map.entrySet(); System.out.println(set1 + " " + collection + " " + set2); Generic Set Example import java.util.*; public class GenSetExample { public static void main(String[] args) { Set set = new HashSet0; set.add("one"); set.add("second"); set.add("3rd"); set.add(new Integer(4)); set.add("second"); System.out.println(set); }}
