Converting a Date object to a calendar object

Question

So I get a date attribute from an incoming object in the form   Tue May 24 05 05 16 EDT 2011   I am writing a simple helper method to convert it to a calendar method  I was using the following code       public static Calendar DateToCalendar Date date        Calendar cal   null   try        DateFormat formatter   new SimpleDateFormat  yyyyMMdd      date    Date formatter parse date toString        cal Calendar getInstance      cal setTime date         catch  ParseException e            System out println  Exception    e             return cal       To simulate the incoming object I am just assigning the values within the code currently using   private Date m lastActivityDate   new Date      However this is givin me a null pointer once the method reaches   date    Date formatter parse date toString

Here s your method   public static Calendar toCalendar Date date      Calendar cal   Calendar getInstance      cal setTime date     return cal      Everything else you are doing is both wrong and unnecessary   BTW  Java Naming conventions suggest that method names start with a lower case letter  so it should be  dateToCalendar or toCalendar  as shown      OK  let s milk your code  shall we   DateFormat formatter   new SimpleDateFormat  yyyyMMdd    date    Date formatter parse date toString        DateFormat is used to convert Strings to Dates  parse    or Dates to Strings  format     You are using it to parse the String representation of a Date back to a Date  This can t be right  can it
