Convert Data date Type

Question

I wanna convert a date from format yyyy/mm/dd to dd/mm/yyyy
and make this code :
Date v_fd = wdContext.currentContextElement().getV_fechadesde();
     Date v_fh = wdContext.currentContextElement().getV_fechahasta();
    String v_fechadesde = v_fd.toString();
     String v_fechahasta = v_fd.toString();
     v_fechadesde = v_fechadesde.substring(8,10) + '-' + v_fechadesde.substring(5,7) + '-' + v_fechadesde.substring(0,4) ;          
     v_fechahasta = v_fechadesde.substring(8,10) + '-' + v_fechahasta.substring(5,7) + '-' + v_fechahasta.substring(0,4) ;
     SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
     java.util.Date d;
     try {
     d = dateFormat.parse(v_fechadesde);
     dateFormat.applyPattern("dd/MM/yyyy");
     v_fechadesde = dateFormat.format(d);
     } catch (Exception e) {
     e.printStackTrace();
     java.sql.Date date = java.sql.Date.valueOf(v_fechadesde);
     wdContext.currentZhr_Rfc_Pce_Get_Object_InputElement().setI_Begda(date);
     wdContext.currentZhr_Rfc_Pce_Get_Object_InputElement().setI_Endda(date);
example
enter
01-06-2007
result
0006-11-28
Any idea please ?

Answer 1

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class MainClass {
     public static void main(String[] args) {
          String dateIn = "01-06-2007";
          String dateIn2 = "1/6/2007";
          try {
               System.out.println("Test Correct Input:"+convertDate(dateIn));
          } catch (Exception e) {
               System.out.println(e.getMessage());
          try {
               System.out.print("Test Wrong Input:");
               System.out.println(convertDate(dateIn2));
          } catch (Exception e) {
               System.out.println(e.getMessage());
      * @param inDate
      * @return
      * @throws Exception
     public static String convertDate(String inDate) throws Exception {
          String inPattern = "dd-mm-yyyy";
          String outPattern = "yyyy-mm-dd";
          String dateOut = null ;
          SimpleDateFormat dateFormatter =  new SimpleDateFormat(inPattern);
          Date date = null;
          try {
               date = dateFormatter.parse(inDate);
          } catch (ParseException e) {
               throw new Exception("Wrong Format");
          SimpleDateFormat formatter = new SimpleDateFormat(outPattern);
          dateOut = formatter.format(date);
          return dateOut;
If the format is incorrect i.e. not in inPattern : dateFormatter.parse(inDate); throws exception.
Go via links i given in first post. You can have more information on date formats there.
