Examples of java.util.Dictionary.keys()

java.util.Dictionary.keys()
Returns an enumeration of the keys in this dictionary. The general contract for the keys method is that an Enumeration object is returned that will generate all the keys for which this dictionary contains entries. @return an enumeration of the keys in this dictionary. @see java.util.Dictionary#elements() @see java.util.Enumeration
