20. DateUtils usage

• Code that uses some of the DateUtils methods:

  
  GregorianCalendar currentGC = new GregorianCalendar();
  int currentYear = currentGC.get( Calendar.YEAR );
  
  Date currentDate = DateUtils.getCurrentDate();
  Date christmas = DateUtils.createDate(
      currentYear, Calendar.DECEMBER, 25 );
  
  int daysToChristmas = DateUtils.daysDiff(
      currentDate, christmas );
  
  DateFormat dateFormat = 
      DateFormat.getDateInstance( DateFormat.LONG );
  String formattedDate = dateFormat.format( currentDate );
  System.out.println( "Today is " + formattedDate );
  System.out.println( "There are " + daysToChristmas + 
      " days until Christmas." );
  
  
  

  Resulting output:

  
  Today is July 11, 2011
  There are 166 days until Christmas.
