下面是说明getAvailableLocales()方法的示例：

范例1：

// Java program to demonstrate 
// getAvailableLocales() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initalizing new simple rule 
            String simple = "< a< b< c< d"; 
  
            // Creating and initializing 
            // new RuleBasedCollator Object 
            RuleBasedCollator col 
                = new RuleBasedCollator(simple); 
  
            // getting all the avalable locale 
            // using getAvailableLocales() mehtod 
            Locale[] locale = col.getAvailableLocales(); 
  
            // display result 
            System.out.println("Equivalent Locales are "); 
            for (int i = 1; i <= 5; i++) 
                System.out.println(locale[i]); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
        catch (ParseException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

输出：

Equivalent Locales are 
ar_AE
ar_JO
ar_SY
hr_HR
fr_BE

范例2：

// Java program to demonstrate 
// getAvailableLocales() method 
  
import java.text.*; 
import java.util.*; 
import java.io.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // Creating and initializing Collator Object 
            Collator col = Collator.getInstance(Locale.UK); 
  
            // getting all the avalable locale 
            // using getAvailableLocales() mehtod 
            Locale[] locale = col.getAvailableLocales(); 
  
            // display result 
            System.out.println("Equivalent Locales are "); 
            for (int i = 6; i <= 10; i++) 
                System.out.println(locale[i]); 
        } 
  
        catch (ClassCastException e) { 
  
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

输出：

Equivalent Locales are
