Java Time Zone Example
Converting time between time zones
In this section we have written a java program which
will take two Time Zone IDs as its argument and then convert the time between
provided time zone IDs.
In our program we have firstly created a new date
object and then after we have created two time zone class's objects with
according to the provided time zone IDs.
TimeZone firstTime = TimeZone.getTimeZone(args[0]);
TimeZone secondTime = TimeZone.getTimeZone(args[1]);
Above lines of code creates two objects of TimeZone
as firstTime and secondTime. We have called getTimeZone()
method to create these objects.
Here is the full example code of ConvertTimeZone.java
as follows:
ConvertTimeZone.java
///////////////////////////////////
// Convert time between time
zone //
///////////////////////////////////
import java.util.Date;
import java.text.SimpleDateFormat;
import java.text.DateFormat;
import java.util.TimeZone;
public class ConvertTimeZone {
public static void main(String[] args) {
Date date = new Date();
DateFormat firstFormat = new SimpleDateFormat();
DateFormat secondFormat = new SimpleDateFormat();
TimeZone firstTime = TimeZone.getTimeZone(args[0]);
TimeZone secondTime = TimeZone.getTimeZone(args[1]);
firstFormat.setTimeZone(firstTime);
secondFormat.setTimeZone(secondTime);
System.out.println("-->"+args[0]+": " + firstFormat.format(date));
System.out.println("-->"+args[1]+": " + secondFormat.format(date));
}
}
|
Output:
Compile the ConvertTimeZone.java file and when
executing them provide the two Time zone Ids from which to which time is to be
converted. Here in above program we have provided two command line arguments as IST
and GMT.
C:\DateExample>javac ConvertTimeZone.java
C:\DateExample>java ConvertTimeZone IST GMT
-->IST: 10/11/08 4:16 PM
-->GMT: 10/11/08 10:46 AM
C:\DateExample> |
