原文:https://www . geesforgeks . org/time zone-getavailableidsint-val _ offset-method-in-Java-with-examples/

Java 中 TimeZone 类的getavailable IDs(intval _ offset)方法用于根据提供的 offset 值获取 TimeZone 类中所有支持的可用 id 列表。

语法:

公共静态字符串[]getAvailableIDs(intval _ offset)

参数:该方法取整数类型的一个参数 val_offset ，该参数是指时区偏移值..

返回值:该方法返回所有可用标识的数组，其中该标识的时区具有指定值。

下面的程序说明了时区的 getAvailableIDs()方法的工作原理:

例 1:

// Java code to illustrate
// getAvailableIDs() method

import java.util.*;

public class TimeZone_Demo {
    public static void main(String args[])
    {

        // Storing all the available Ids
        String[] Id_array
            = TimeZone.getAvailableIDs(7200000);

        // Displaying all the available Ids
        System.out.println("All the available"
                           + " Ids are: ");

        for (int count = 0;
             count < Id_array.length;
             count++)
            System.out.println(Id_array[count]);
    }
}

输出:

All the available Ids are:
