Options for iterating through maps

Not really. But you could do

System.out.println(iterator.next());

You can print the whole map by doing:
System.out.println(map);

Which will print it in this format "[key1=value1, key2=value2,... ]"

objects, Is your suggestion simpler then the one provided rayskelton

Of the two available options, is there a performance hit for one against the other?

    // get iterator of map through map.entries
    Set entries = map.entrySet();
    Iterator iterator = entries.iterator();
    while (iterator.hasNext()) {
      Map.Entry entry = (Map.Entry)iterator.next();
//      dest.write("Key:" + entry.getKey() + " : Message:" + entry.getValue() + "\n");
      dest.write(entry.getKey() + " :: " + entry.getValue() + "\n");
//      dest.write("Message:" + entry.getValue() + "\n");
    }
   
    Iterator iterator1 = map.keySet().iterator();
    dest.write("\nOption 2 for map writing\n");
    while (iterator1.hasNext()) {
      Object key = iterator1.next();
      Object value = map.get(key);
      dest.write(key + " :: " + value + "\n");
    }
 

I use the following snippet so often that I've made it a macro-template in my JBuilder:

    Map.Entry entry = null;
    for (Iterator iter = map.entrySet().iterator(); iter.hasNext();) {
      entry = (Map.Entry)iter.next();
      Object key = entry.getKey();
      Object value = entry.getValue();
      // Do whatever with the key and value..
    }

Doubt there would be any significant performance difference, suggest you benchmark if you are dealing with large sets and performance is an issue

thanks for all advice
