以下程序说明了日历类 getAvailableLocales()方法的工作: 示例 1:

// Java Code to illustrate
// getAvailableLocales() Method

import java.util.*;

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

        // Creating a locale object
        Locale loc_arr[] = new Locale[5];

        // Assigning locales to array
        loc_arr = Locale.getAvailableLocales();

        // Displaying the results
        System.out.println("The first "
                           + "five locales are:");

        for (int cnt = 0; cnt < 5; cnt++)
            System.out.println(
                loc_arr[cnt]
                    .getISO3Country());
    }
}

Output:

The first five locales are:

ARE
JOR
SYR
HRV

例 2:

// Java Code to illustrate
// getAvailableLocales() Method

import java.util.*;

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

        // Creating a locale object
        Locale loc_arr[] = new Locale[20];

        // Assigning locales to array
        loc_arr = Locale.getAvailableLocales();

        // Displaying the results
        System.out.println("The first "
                           + "twenty availables"
                           + " locales are:");

        for (int cnt = 0; cnt < 20; cnt++)
            System.out.println(
                loc_arr[cnt]
                    .getISO3Country());
    }
}

Output:

The first twenty availables locales are:

ARE
JOR
SYR
HRV
