java - Convert string date to ISO format date

I need to convert some string date to another format string date

String current = "Tue Apr 16 10:59:11 EDT 2019";

I want to get result date String in format ISO-8601 in accordance with the pattern - "yyyy-MM-dd'T'HH:mm:ss.SSSXX"

Could you please help me to implement this?

Answer

Using Java8 DateTime API you can do something like following:

     //your input
     String date = "Tue Apr 16 10:59:11 EDT 2019";
     //create new formatter for parsing your input
     DateTimeFormatter formatter = DateTimeFormatter.ofPattern("EEE MMM d HH:mm:ss zzz yyyy", Locale.ENGLISH);
     //create new zonedDateTime from parsing an input with provided formatter
     ZonedDateTime zonedDateTime = ZonedDateTime.parse(date,formatter);

Get it in the format of your own:

     //format your zonedDateTime with a new provided pattern
     String test = zonedDateTime.format(DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSSXX"));
     //print it
     System.out.println(test);
