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: Program 1: 

// Java program to demonstrate
// ZonedDateTime.parse() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // 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);
    }
}

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. Below programs illustrate the parse() method: Program 1: 

// Java program to demonstrate
// ZonedDateTime.parse() method

import java.time.*;
import java.time.format.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a formatter
        DateTimeFormatter formatter
            = DateTimeFormatter
                  .ISO_ZONED_DATE_TIME;

        // create an ZonedDateTime object and
        ZonedDateTime zdt
            = ZonedDateTime
                  .parse("2018-12-16T20:28:33.213+05:30[Asia/Calcutta]",
                         formatter);

        // print result
        System.out.println("ZonedDateTime : "
                           + zdt);
    }
}

ZonedDateTime : 2018-12-16T20:28:33.213+05:30[Asia/Calcutta]
