Date of Java
1. The title is not written, you will know after running.
import java.util.Date; import java.text.SimpleDateFormat; public class Demo {public static void main (String [] args) {Date now = new Date (); SimpleDateFormat f = new SimpleDateFormat ( "Today is" "yyyy Year MM DD Day E KK Point MM Division "); system.out.println (f.Format (now)); f = new simpledateformat (" A hh point mm ss second "); system.out.println (f .format (now);}}
You can think about it first before running, see if you think is the same.
2. Conversion from strings to date types:
import java.util.Date; import java.text.SimpleDateFormat; import java.util.GregorianCalendar; import java.text *;. public class Demo {public static void main (String [] args) {String strDate = "2005-04 "22nd";
// Note: The style of SimpleDateFormat constructor with strdate's style must match SimpleDateFormat SimpleDateFormat = New SimpleDateFormat ("YYYY MM Moon DD Day);
/ / Must capture exception Try {date Date = SimpleDateFormat.Parse (strdate); system.out.println (date);} catch (parseException px) {px.printstacktrace ();}}}
3. Transform milliseconds into a date type:
import java.util.Date; import java.text.SimpleDateFormat; import java.util.GregorianCalendar; import java.text *;. public class Demo {public static void main (String [] args) {long now = System.currentTimeMillis ( ); System.out.println ("Count:" now); Date DNOW = New Date (NOW); System.out.Println ("Date Type: DNOW);}}
