From Java Tutorial 98- 4: Multi-Treading, Useful Java Classes, I/O and Networking NAVO Tutorial -- Sept 23 1998. by Geoffrey C. Fox, Nancy McCracken
1 This class provides an implementation of "date" structures. Date has methods to create and compare dates, obtain and set the time, and convert dates to strings.
2 The Date constructor creates today's date:
  • Date today = new Date();
3 In Java 1.1, most Date methods have been deprecated in favor of the Calendar class:
  • Calendar date1 = Calendar.getInstance();
  • date1.set( 999, 12, 31 ); /* Dec. 31, 999 */
  • Calendar date2 = Calendar.getInstance();
  • date2.set( 1996, 12, 31, 23, 59, 59 )
    • /* Dec.31,1996 at 23:59:59 */
