Java中的 Calendar getTimeZone() 方法及示例

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

句法：

public TimeZone getTimeZone()

参数：该方法不带任何参数。
返回值：该方法返回此日历对象的时区。

下面的程序说明了 Calendar 类的 getTimeZone() 方法的工作：
示例 1：

Java

// 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

示例 2：

Java

// 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
