Changing the date format from mm/dd/yyyy

Question

I need to change the date format from 2015-04-08 to 08-APR-2015. It is coming from grails gsp front end. Before calling oracle package I need to change the format in java. How to do it.

Do you want to format date at client side (javascript) or server side (java)? because you mentioned java in your question while tagged javascript? — Sameer Azazi, Apr 27 '15 at 05:02

I use SimpleDateFormat in changing date formats. Try this:

String OLD_FORMAT = "yyyy-MM-dd";
String NEW_FORMAT = "dd-MMM-yyyy";

String oldDateString = "2015-04-08";
String newDateString;

SimpleDateFormat sdf = new SimpleDateFormat(OLD_FORMAT);
Date d = sdf.parse(oldDateString);
sdf.applyPattern(NEW_FORMAT);
newDateString = sdf.format(d);

You mentioned Java in your answer but you tagged JavaScript I've edited your question to show the Java tag. This is a JavaScript soution.

Assuming str is you input:

str.split('-').forEach(function(a,i,b){
    result += i===0?(b[2]+'-'):i===1?(((new Date(str)).toUTCString()).split(' ')[2]+'-').toUpperCase():a[0];
});

Ok I already see and answer but still want to add one.I am not sure you want JS or Java solution. You can this using Javascript or Java. Below are both ways:
Javascript

var c = new Date('2015-04-08');
locale = "en-us" 
function formatDate(d)
 {
    var month = d.toLocaleString(locale, { month: "long" });
    var day = d.getDate();
    day = day + "";
    if (day.length == 1)
     {
     day = "0" + day;
      }
      return day + '-' + month +'-' + d.getFullYear();
  }

And if you want same in Java you do below..
Java

String myDateString = "2015-04-08";
String reqDateString = new SimpleDateFormat("dd-MMM-yyyy").format(myDateString);

Better if done in Java looks more simpler and reliable..

Yes,done.Was able to do in server side.I was missing some syntax — Debasis Mohapatra, Apr 27 '15 at 05:40
