Date The class Date represents a specific instant in time, with millisecond precision.

Hashtable This class implements a hashtable, which maps keys to values.

Random An instance of this class is used to generate a stream of pseudorandom numbers.

Stack The Stack class represents a last-in-first-out (LIFO) stack of objects.

TimeZone TimeZone represents a time zone offset, and also figures out daylight savings.

Vector The Vector class implements a growable array of objects.

Exception Summary
