How can I process through the keys of a Hashtable in sorted order?
John Zukowski In order to get all the keys for a Hashtable, you use the keys() method to get an Enumeration or the keySet() method to get a Set. If you are using Java 2, and can use the collections framework, what you should do is get the key set of the Hashtable and create a TreeSet from it. You can then get an iterator() from the created TreeSet that will have the keys in order. If you can't use the collections framework, you'll have the sort the Enumeration you get back from keys() yourself.
