Getting unparsable date error in groovy script

Question

I have below code snippet : java.util.Calendar calendar = java.util.Calendar.getInstance();

curdate = "2025-01-31T12:27:00"  
  def parsedDate = new Date().parse("yyyy-MM-dd'T'HH:mm:ss", curdate)
  calendar.setTime(parsedDate);
  curhour = calendar.get(Calendar.HOUR_OF_DAY);
  curmin = calendar.get(Calendar.MINUTE);

I want to parse curdate "2025-01-31T12:27:00" into parsable format but it is throwing below excpetion :

can anyone plase help me how to parse the date in this format ? this is in groovy script

Please edit your question to convert images into text, and use a [code block] for any code you have. Readers can then search the text or run the code to reproduce your issue. — cfrick

Which Date class did you import? It doesn't look to me like java.util.Date. — Dawood ibn Kareem

You can import java.time.LocalDateTime and use its function LocalDateTime.parse(curdate) which will at least work for your example value of curdate because it has the expected format. — deHaar

And then curHour = ldt.toLocalTime().getHour();curMin = ldt.toLocalTime().getMinute(); You should be doing this as java.util.Date has long been superseded — g00se

tl;dr

LocalDateTime.parse ( "2025-01-31T12:27:00" )

Two `Date` classes

Java includes two classes named Date, java.util.Date and java.sql.Date. The first represents a moment as seen with an offset from UTC of zero hours-minutes-seconds. The second pretends to represent a date-only value, but actually contains a moment. We cannot tell which you tried to utilize.

Both classes are terribly-flawed, both are legacy, and both should be avoided. So your Question is moot. You should instead be using only the java.time classes for your date-time work. Never use Date, Calendar, SimpleDateFormat, etc.

`java.time.LocalDateTime`

Neither of those legacy classes is meant to represent the content of your input text. Your input text contains a date with a time-of-day but lacks the context of a time zone or offset. So parse as a LocalDateTime object.

Your input text complies with the standard ISO 8601 used by default in the java.time classes. So no need to specify a formatting pattern.

String input = "2025-01-31T12:27:00" ;
LocalDateTime ldt = LocalDateTime.parse ( input ) ;

The exception you get means that you must include Groovy Date Time extension to your dependencies.

then you'll be able to write code as simple as:

String curdate = "2025-01-31T12:27:00"  
Date parsed = Date.parse "yyyy-MM-dd'T'HH:mm:ss", curdate
Stirng HHmm = parsed.format 'HH:mm'

If you for whatever reason can not change your deps, then you can either use SimpleDateFormat or other datetime facilities from JDK.
