I have a day of the week number: 2 (which should match to Tuesday if week start on Monday).
From this number is there a way to get the name of the day in Java using Joda Time? In javascript it has been quite easy to do it using moment.js:
moment().day(my number)
At least this works, although I consider it as not so nice:
LocalDate date = new LocalDate();
date = date.withDayOfWeek(2);
System.out.println(DateTimeFormat.forPattern("EEEE").print(date));
Unfortunately Joda-Time does not offer an enum for the day of week (java.time does). I have not quickly found another way in the huge api. Maybe some Joda-experts know a better solution.
Added (thanks to @BasilBourque):
LocalDate date = new LocalDate();
date = date.withDayOfWeek(2);
System.out.println(date.dayOfWeek().getAsText());
In java.time (JSR 310, Java 8 and later), use the DayOfWeek
enum.
int day = 2;
System.out.println( DayOfWeek.of(2).getDisplayName(TextStyle.FULL, Locale.ENGLISH) );
// Output: Tuesday
You can use a particular enum instance directly rather than a magic number like 2
. The DayOfWeek
enum provides an instance for each day of week such as DayOfWeek.TUESDAY
.
System.out.println( DayOfWeek.TUESDAY.getDisplayName(TextStyle.FULL, Locale.ENGLISH) );
// Output: Tuesday
For making it complete, here the solution of old JDK:
int day = 2;
DateFormatSymbols dfs = DateFormatSymbols.getInstance(Locale.ENGLISH);
System.out.println(dfs.getWeekdays()[day % 7 + 1]);
