How to convert the date format 19-Mar-15 to 19-Mar-2015 in java

[Minal Abhijit Urankar]

You need to use SimpleDateFormat which can be imported from java.text.* API.

      Date dNow = new Date( );
      SimpleDateFormat ft = new SimpleDateFormat ("dd-MMM-yy");
      System.out.println("Date 1 : " + ft.format(dNow));
      
      SimpleDateFormat ft1 = new SimpleDateFormat ("dd-MMM-yyyy");
      System.out.println("Date 2: " + ft1.format(dNow));

Output is as followes:

Date 1 : 20-Mar-15
Date 2: 20-Mar-2015

Link for SimpleDateFormat java docs:java.lang.SimpleDateFormat

Hi Minal Abhijit Urankar,

Actually i am getting string form of date object in jsp.

like,

<%=checkForNull((String)resultset.get("MAKER_DATE"))%>

Here Maker date value displaying like '19-Mar_15' , But i want display format like '19-Mar-2015'.

Apparently the date you get is a String, not a Date object.

You can parse the string using a SimpleDateFormat with the pattern "dd-MMM-yy", and then format the resulting Date object with another SimpleDateFormat with the pattern dd-MMM-yyyy.

Why are you storing a date value in a database as a String?
If it was a DATE then you could either format using a SimpleDateFormat (as mentioned) or change the SQL to return the DATE as a pre-formatted String.

As it stands you now have to convert the String to a Date and the back again to a String...

Hi Minal Abhijit Urankar,

it's working fine.

I Have written the code like this,


<%
String s_Date=checkForNull((String)resultset.get("MAKER_DATE"));
SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yy");
Date date = formatter.parse(s_Date);
SimpleDateFormat ft1 = new SimpleDateFormat ("dd-MMM-yyyy");
String s_Cdate=ft1.format(date);
%>



Thanks for your helping.....

If at all possible stop using Date and use this instead (or this).

Just noticed as well.
Why are you using get() from ResultSet and then casting to String rather than using the getString() method on ResultSet.
You know the datatype after all.
