How to convert String to ZonedDateTime using ZonedDateTime.parse() method

In Java, we can use the ZonedDateTime.parse(CharSequence text) static method to parse a String value to a ZonedDateTime object as the Java code below.

ConvertStringToZonedDateTimeExample1.java 

import java.time.ZonedDateTime;

public class ConvertStringToZonedDateTimeExample1 {
    public static void main(String... args) {
        ZonedDateTime zonedDateTime1 = ZonedDateTime.parse("2022-05-26T08:15:30+07:00[Asia/Ho_Chi_Minh]");
        ZonedDateTime zonedDateTime2 = ZonedDateTime.parse("2022-05-26T08:15:30+10:00[Australia/Sydney]");
        ZonedDateTime zonedDateTime3 = ZonedDateTime.parse("2022-05-26T08:15:30+02:00[Europe/Paris]");
        ZonedDateTime zonedDateTime4 = ZonedDateTime.parse("2022-05-26T08:15:30+09:00[Asia/Tokyo]");

        System.out.println(zonedDateTime1);
        System.out.println(zonedDateTime2);
        System.out.println(zonedDateTime3);
        System.out.println(zonedDateTime4);
    }
}
The output as below. 
2022-05-26T08:15:30+07:00[Asia/Ho_Chi_Minh]
2022-05-26T08:15:30+10:00[Australia/Sydney]
2022-05-26T08:15:30+02:00[Europe/Paris]
2022-05-26T08:15:30+09:00[Asia/Tokyo]

How to convert String to ZonedDateTime with custom date time format

Using the java.time.format.DateTimeFormatter class we convert a String in specified zoned date time format to ZonedDateTime object as the following example Java code.

ConvertStringToZonedDateTimeExample2.java 

import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;

public class ConvertStringToZonedDateTimeExample2 {
    public static void main(String... args) {
        DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss z");
        ZonedDateTime zonedDateTime = ZonedDateTime.parse("2022-04-26 09:30:40 +07:00", dateTimeFormatter);

        System.out.println("ZonedDateTime: " + zonedDateTime);
    }
}
The output as below. 
ZonedDateTime: 2022-04-26T09:30:40+07:00
