Question

How do i convert the below date:

Apr 29, 2022 to 04/29/20222

So basically my input date in format Mon dd, yyyy should be converted to mm/dd/yyyy

Answer 1

Use DateTimeFormatter and LocalDate

String date = "Apr 29, 2022";
DateTimeFormatter fromFormat = DateTimeFormatter.ofPattern("MMM dd, yyyy")
         .withLocale(Locale.US);
DateTimeFormatter toFormat = DateTimeFormatter.ofPattern("MM/dd/yyyy");
LocalDate localDate = LocalDate.parse(date,fromFormat);
System.out.println(localDate.format(toFormat));

prints

04/29/2022
