To get the day of the week from a java.util.Date object, we can use the java.text.SimpleDateFormat class. First, create a Date object. Next, create a SimpleDateFormat instance using the getDateInstance() method, passing the String “E” or “EEEE” as the argument. Get the day of the week as a String using the format() method passing in the java.util.Date object. To get the weekday in numerical format, we can use the java.util.Calendar object’s get method passing in Calendar.DAY_OF_WEEK.

// // The following example code demonstrates how to // print out the Day of the Week from a Date object. // public class GetDayFromDate { public static void main(String[] args) { Date now = new Date(); SimpleDateFormat simpleDateformat = new SimpleDateFormat("E"); // the day of the week abbreviated System.out.println(simpleDateformat.format(now)); simpleDateformat = new SimpleDateFormat("EEEE"); // the day of the week spelled out completely System.out.println(simpleDateformat.format(now)); Calendar calendar = Calendar.getInstance(); calendar.setTime(now); System.out.println(calendar.get(Calendar.DAY_OF_WEEK)); // the day of the week in numerical format } } |
Here is the output of the example code for getting the day of the week:
