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

语法:

public TimeZone getTimeZone()

参数:该方法不取任何参数。 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 getTimeZone()方法的工作: 示例 1:

Java 语言(一种计算机语言，尤用于创建网站)

// 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());
    }
}

Output: 

The current Time zone is: Coordinated Universal Time

例 2:

Java 语言(一种计算机语言，尤用于创建网站)

// 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());
    }
}

Output: 

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