日期

public class date_time {

     /**

      * @param args

      */

     public static void main(String[] args) {

           // TODO Auto-generated method stub

           GregorianCalendar time=new GregorianCalendar();//创建time对象

          

          System. out.println(time.get(Calendar.YEAR));//获取当前系统日期

          System. out.println(time.get(Calendar.MONTH)+1);//获取系统月份是要加一

        System. out.println(time.get(Calendar.DATE));

          System. out.println(time.get(Calendar.HOUR));

           GregorianCalendar time1=new GregorianCalendar ();

          time1.set(2014,4,9);

          System. out.println(time1.get(Calendar.YEAR));//获取你当前设置的日期

          System. out.println(time1.get(Calendar.MONTH));

          System. out.println(time1.get(Calendar.DATE));

     }

}

结果
