Hi friend,

Code to solve the problem :

import java.util.Date;
import java.util.Locale;
import java.util.Calendar;
import java.text.SimpleDateFormat;

public class AddDaysToDate {

public static Calendar parseTimestamp(String timestamp)
throws Exception {
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy", Locale.US);
Date d = sdf.parse(timestamp);
Calendar cal = Calendar.getInstance();
cal.setTime(d);
return cal;
}

public static void main (String a[]) throws Exception{
String timestampToParse = "02-Dec-2008";
System.out.println("Date is : " + timestampToParse);
Calendar cal = parseTimestamp(timestampToParse);
cal.add(Calendar.DATE, 45);
Date d = new Date(cal.getTime().getTime());
SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy");
String formattedDate = formatter.format(d);
System.out.println("After 45 Days date is ==>"+formattedDate);
}
}
