I am trying to convert the string to date and i want that date to be in this format 'yyyy-MM-d HH:mm:ss' and i no how to get this format in string my question is i want to get Date in above format not as string but as 'Date '?

i am doing in this way

for(int k=0;k<12;k++)//for the months
{
     //i have added if condtion for the months with 31 and 30 and 28 days
    Calendar dateFromCal = Calendar.getInstance();
    dateFromCal.setTime(date);
    dateFromCal.set(year, k, 1, 0, 0, 0);

    Calendar dateToCal = Calendar.getInstance();
    dateToCal.setTime(date);
    dateToCal.set(year, k, 31, 23, 59, 59);

    //i have set the date format as 'yyyy:MM:dd HH:mm:ss'  
    dateFrom = dateFormat.format(dateFromCal.getTime());
    dateTo = dateFormat.format(dateToCal.getTime());

    fromdate = (Date)dateFormat.parse(dateFrom);
    todate = (Date)dateFormat.parse(dateTo);

}
