java.util collections classes page 8 of 11

The CLDC java.util package contains the most frequently used classes from the J2SE java.util package. These include four of the collections classes -- actually three classes and one interface -- as well as date/time and utility classes.

The java.util collections classes supported by CLDC are:

  • Enumeration -- An interface that allows the calling routine to iterate through a collection of items, one at a time.

  • Hashtable -- Implements a hashtable, which maps keys to values.

  • Stack -- Represents a last-in-first-out (LIFO) collection or stack of objects.

  • Vector -- Represents a resizable "array," or vector, of objects.
