Java 日历 getTimeZone()方法及示例

Calendar类中的 getTimeZone() 方法用于返回该日历的当前时区。

语法

public TimeZone getTimeZone()

参数： 该方法不接受任何参数。

返回值： 该方法返回该日历对象的时区。

下面的程序说明了日历类的getTimeZone()方法的工作情况：

例1 :

// Java code to illustrate
// getTimeZone() method
 
import java.util.*;
 
public class Calendar_Demo {
    public static void main(String args[])
    {
        // Creating a calendar object
        Calendar calndr = Calendar.getInstance();
 
        // Getting the time zone of calendar
        TimeZone time_zone = calndr.getTimeZone();
 
        // Displaying the current time zone
        System.out.println("The current Time zone is: "
                           + time_zone.getDisplayName());
    }
}

输出

The current Time zone is: Coordinated Universal Time

例2 :

// Java code to illustrate
// getTimeZone() method
 
import java.util.*;
 
public class Calendar_Demo {
    public static void main(String args[])
    {
        // Creating a calendar object
        Calendar calndr = Calendar.getInstance();
 
        // Getting the time zone of calendar
        TimeZone time_zone = calndr.getTimeZone();
 
        // Displaying the current time zone
        System.out.println("The current Time zone is: "
                           + time_zone.getDisplayName());
 
        // Changing the time zone
        calndr.setTimeZone(
            TimeZone.getTimeZone("GMT"));
 
        System.out.println("New TimeZone: "
                           + calndr.getTimeZone()
                                 .getDisplayName());
    }
}

输出

The current Time zone is: Coordinated Universal Time
New TimeZone: Greenwich Mean Time
