public class MapEntrySetDemo {

public static void main(String[] argv) {

Map map = new HashMap();

map.put("Adobe", "Mountain View, CA");
map.put("IBM", "Mountain View, CA");
map.put("Learning Tree", "Los Angeles, CA");
map.put("Microsoft", "Redmond, WA");
map.put("Netscape", "Mountain View, CA");
map.put("O'Reilly", "Sebastopol, CA");
map.put("Sun", "Mountain View, CA");

Set entries = map.entrySet();
Iterator it = entries.iterator();
while (it.hasNext()) {
Map.Entry entry = (Map.Entry) it.next();
if("Mountain View, CA".equals(entry.getValue()))
{
System.out.println(entry.getKey() );
