For Example I have the date: “23/2/2010” (23th Feb 2010). I want to pass it to a function which would return the day of week. How can I do this?
In this example, the function should return
Additionally, if just the day ordinal is desired, how can that be retrieved?
Yes. Depending on your exact case:
You can use
Calendar c = Calendar.getInstance(); c.setTime(yourDate); int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
if you need the output to be
Tuerather than 3 (Days of week are indexed starting at 1 for Sunday, see Calendar.SUNDAY), instead of going through a calendar, just reformat the string:
EEmeaning “day of week, short version”)
if you have your input as string, rather than
Date, you should use
SimpleDateFormatto parse it:
you can use joda-time’s
edit: since Java 8 you can now use java.time package instead of joda-time
