How to use an iCal calendar in a Java program from a calendar URL?

Question

Currently I am using 2 tools to start processing an iCal calendar from URL. First, using Google Chrome I create a .ics file from the calendar URL (for example I can get URL from AirBnb) and then I use ical4j to process the created file. Is there any way to use this URL directly in the Java program?

Answer 1

Probably something like:

InputStream is = new URL("http://airbnb.com/ical/").openStream();
try {
   Calendar cal = new CalendarBuilder().build(is);
} finally {
  is.close();
}
