Hi,

Here is the example program:

package net.roseindia;

import java.sql.Timestamp;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

/*
 * Example of formatting date in Java 
 */
public class FormatDate {

    public static void main(String[] args) {

        String dt = "10-Dec-2017";
        String pattern = "dd-MMM-yyyy";
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat(pattern);
        Date date = null;
        try {
            date = simpleDateFormat.parse(dt);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        System.out.println("Date:" + date);

    }

}

In this example we are using the following code:

 SimpleDateFormat simpleDateFormat =
    new SimpleDateFormat(pattern);

The use following code to format it to date:

date = simpleDateFormat.parse(dt);

Thanks
