How to deal with time zones in Java8

Handling time zones in Java 8

Java 8 not only separates date and time, but also separates time zones. There are now a series of separate classes such as ZoneId to handle specific time zones and ZoneDateTime to represent time in a certain time zone. This was done by the GregorianCalendar class before Java 8. The following example shows how to convert the time in this time zone to the time in another time zone.

package com.shxt.demo02;  
import java.time.LocalDateTime;  
import java.time.ZoneId;  
import java.time.ZonedDateTime;  
public class Demo12 {      
public static void main(String[] args) {          
// Date and time with timezone in Java 8         
ZoneId america = ZoneId.of("America/New_York");          
LocalDateTime localtDateAndTime = LocalDateTime.now();          
ZonedDateTime dateAndTimeInNewYork  = ZonedDateTime.of(localtDateAndTime, america );          
System.out.println("Current date and time in a particular timezone : " + dateAndTimeInNewYork);      
}  
}
