ZonedDateTime parse() method in Java with Examples

In ZonedDateTime class, there are two types of parse() method depending upon the parameters passed to it.

parse(CharSequence text)

parse() method of a ZonedDateTime class used to get an instance of ZonedDateTime from a string such as ‘2018-12-06T19:21:12.123+05:30[Asia/Calcutta]’ passed as parameter. The string must have a valid date-time and is parsed using DateTimeFormatter.ISO_ZONED_DATE_TIME.

Syntax:



public static ZonedDateTime parse(CharSequence text)

Parameters: This method accepts only one parameter text which is the text to parse in ZonedDateTime. It should not be null.

Return value: This method returns ZonedDateTime which is the parsed local date-time.

Exception: This method throws DateTimeParseException if the text cannot be parsed.

Below programs illustrate the parse() method:

        // create an ZonedDateTime object
        ZonedDateTime zoneddatetime2
            = ZonedDateTime
                  .parse(
                      "2018-12-26T20:28:33.213+05:30[Asia/Calcutta]");
  
        // print result
        System.out.println("ZonedDateTime : "
                           + zoneddatetime2);
    }
}

Output:

ZonedDateTime : 2018-12-26T20:28:33.213+05:30[Asia/Calcutta]

parse(CharSequence text, DateTimeFormatter formatter)

parse() method of a ZonedDateTime class used to get an instance of ZonedDateTime from a string such as ‘2018-12-06T19:21:12.123+05:30[Asia/Calcutta]’ passed as parameter using a specific formatter.The date-time is parsed using a specific formatter.

Syntax:

public static ZonedDateTime parse(CharSequence text,
                                  DateTimeFormatter formatter)

Parameters: This method accepts two parameters text which is the text to parse and formatter which is the formatter to use.

Return value: This method returns ZonedDateTime which is the parsed local date-time.


Exception: This method throws DateTimeParseException if the text cannot be parsed.
