LocalDateTimeDemo.java

import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.ZonedDateTime;

public class LocalDateTimeDemo
{

    public static void main(String[] args)
    {
        LocalDateTime localDateTime = LocalDateTime
                .parse("2017-05-03T12:30:30");

        System.out.println(localDateTime);

        ZoneId zoneId = ZoneId.systemDefault();
        System.out.println("zoneId = "+zoneId);

        /*
         * Parameters:
         *
         * zone - the time-zone to use, not null
         *
         * Returns:
         *
         * the zoned date-time formed from this date-time, not null
         */
        ZonedDateTime zonedDateTime = localDateTime.atZone(zoneId);

        System.out.println(zonedDateTime);

    }

}

Output

2017-05-03T12:30:30
zoneId = Asia/Calcutta
2017-05-03T12:30:30+05:30[Asia/Calcutta]
