Conversion between Java time and string

1. Long string converted to YYYY-MM-DD HH:mm:ss format output

Import java.text.simpledateformat;import java.util.date;//Convert long string to format time output public class Longtostring {public static void main (String argsp[]) {string time= "1256006105375";D ate date=new Date (Long.parselong (time)); SimpleDateFormat formatter=new SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss"); Time=formatter.format (date); System.out.println (time);}}

2. String conversion into Time

Import Java.text.simpledateformat;import Java.util.date;import ognl. Parseexception;public class Stringtodate {public static void main (String argsp[]) throws Exception{string time= " 2010-11-20 11:10:10 ";D ate date=null; SimpleDateFormat formatter=new SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss");d Ate=formatter.parse (time); SYSTEM.OUT.PRINTLN (date);}}

3. Get current system time, return YYYY-MM-DD HH:mm:ss string

Import Java.text.simpledateformat;import Java.util.date;public class Stringtodate {public static void main (String ARGSP []) throws Exception{date date=new Date (); SimpleDateFormat formatter=new SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss"); String Time=formatter.format (date); System.out.println (time);}}

4. Get current system time, return HH:MM:SS string

Import Java.text.simpledateformat;import Java.util.date;public class Stringtodate {public static void main (String ARGSP []) throws Exception{date date=new Date (); SimpleDateFormat formatter=new SimpleDateFormat ("HH:mm:ss"); String Time=formatter.format (date); System.out.println (time);}}

5. Convert 20101125102503 to 2010-11-25 10:25:03 output

Import Java.text.simpledateformat;import Java.util.date;public class Stringtodate {public static void main (String ARGSP []) throws exception{string time= "20101125102503"; SimpleDateFormat formatter1=new SimpleDateFormat ("Yyyy-hh-dd HH:mm:ss"); SimpleDateFormat formatter2=new SimpleDateFormat ("Yyyyhhddhhmmss"); Time=formatter1.format (Formatter2.parse (Time) ); System.out.println (time);}}
