Working with Date class in java,Converting String to Date

import java.text.DateFormat; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Date; //This examples are used to take date in string format and stored in date object public class DateExamples { public static void main(String[] args) { System.out.println("+++++++++++++++++++++++++++++++++"); //Just displaying today date in required format DateFormat df = new SimpleDateFormat("dd/yy/MM"); String formattedDate = df.format(new Date()); System.out.println("TO DAY DATE IS:"+formattedDate); System.out.println("+++++++++++++++++++++++++++++++++"); System.out.println("+++++++++++++++++++++++++++++++++"); //In this format only we have to give the date SimpleDateFormat formatter = new SimpleDateFormat ("dd-MMM-yyyy"); String dateInString = "7-Jun-2013"; try { Date date = formatter.parse(dateInString); System.out.println(date); System.out.println(formatter.format(date)); } catch (ParseException e) { e.printStackTrace(); } System.out.println("+++++++++++++++++++++++++++++++++"); System.out.println("+++++++++++++++++++++++++++++++++"); //In this format only we have to give the date SimpleDateFormat formatter1 = new SimpleDateFormat ("dd/MM/yyyy"); String dateInString1 = "07/06/2013"; try { Date date = formatter1.parse(dateInString1); System.out.println(date); System.out.println(formatter1.format(date)); } catch (ParseException e) { e.printStackTrace(); } System.out.println("+++++++++++++++++++++++++++++++++"); System.out.println("+++++++++++++++++++++++++++++++++"); //In this format only we have to give the date SimpleDateFormat formatter2 = new SimpleDateFormat ("MMM dd, yyyy"); String dateInString2 = "Jun 7, 2013"; try { Date date = formatter2.parse(dateInString2); System.out.println(date); System.out.println(formatter2.format(date)); } catch (ParseException e) { e.printStackTrace(); } System.out.println("+++++++++++++++++++++++++++++++++"); System.out.println("+++++++++++++++++++++++++++++++++"); //In this format only we have to give the date SimpleDateFormat formatter3 = new SimpleDateFormat ("E, MMM dd yyyy"); String dateInString3 = "Fri, June 7 2013"; try { Date date = formatter3.parse(dateInString3); System.out.println(date); System.out.println(formatter3.format(date)); } catch (ParseException e) { e.printStackTrace(); } System.out.println("+++++++++++++++++++++++++++++++++"); System.out.println("+++++++++++++++++++++++++++++++++"); //In this format only we have to give the date SimpleDateFormat formatter4 = new SimpleDateFormat ("EEEE, MMM dd, yyyy HH:mm:ss a"); String dateInString4 = "Friday, Jun 7, 2013 12:10:56 PM"; try { Date date = formatter4.parse(dateInString4); System.out.println(date); System.out.println(formatter4.format(date)); } catch (ParseException e) { e.printStackTrace(); } System.out.println("+++++++++++++++++++++++++++++++++"); System.out.println("+++++++++++++++++++++++++++++++++"); //In this format only we have to give the time SimpleDateFormat formatter5 = new SimpleDateFormat ("HH:mm:ss a"); String dateInString5 = "12:10:56 PM"; try { Date date = formatter5.parse(dateInString5); //System.out.println(date); System.out.println(formatter5.format(date)); } catch (ParseException e) { e.printStackTrace(); } System.out.println("+++++++++++++++++++++++++++++++++"); System.out.println("+++++++++++++++++++++++++++++++++"); //It just displaying current date and time in required format SimpleDateFormat formatter6 = new SimpleDateFormat ("yyyy/MM/dd EEE,hh:mm::ss a"); System.out.println(formatter6.format(new Date())); System.out.println("+++++++++++++++++++++++++++++++++"); System.out.println("+++++++++++++++++++++++++++++++++"); //It just displaying current date and time in required format SimpleDateFormat formatter7 = new SimpleDateFormat ("yyyy/MMMM/dd EEE,hh:mm::ss a"); System.out.println(formatter7.format(new Date())); System.out.println("+++++++++++++++++++++++++++++++++"); } }

OUTPUT:

Spring MVC working Flow

By using URL/From jsp we are sending request

This request will come to web.xml file and execute DispatcherServlet

It is the responsibility of DispatcherServlet to identify perticular HandlerMappings

By using HandlerMapping DispathcerServlet will search for requested url path matching in spring configuration file/Spring Configuration class

If it is available,DispatcherServlet will call methods in our Controller

Controller process the request,get the data form form,store into pojo class/javabean,if required perform validations

And then Controller returns ModelAndView object with data/errors and jsp name

DispatcherServlet take the ModleAndView object and stored in scoped variables

Based on the jsp name returned by Controller,DispatcherServlet will find out jsp by using ViewResolver(InternalResourceViewResolver)

Finally loginpage/successpage/failure page send to clietnt/jsp/other

By using scoped variables we can display the data/errors
