Java中的 TimeZone getAvailableIDs(int val_offset) 方法及示例
Java中TimeZone 类的getAvailableIDs(int val_offset )方法用于根据提供的偏移值获取 TimeZone 类中所有支持和可用的 ID 的列表。
句法:
public static String[] getAvailableIDs(int val_offset)
参数:该方法接受一个I nteger类型的参数val_offset ,它指的是时区偏移值。
返回值:该方法返回所有可用 ID 的数组,其中该 ID的时区具有指定值。
下面的程序说明了 TimeZone 的 getAvailableIDs() 方法的工作:
示例 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:
