以下示例程序旨在说明SimpleDateFormat的setDateFormatSymbols()方法的用法：
示例1:

// Java code to illustrate 
// DateFormatSymbols() method 
  
import java.text.*; 
import java.util.*; 
  
public class SimpleDateFormat_Demo { 
    public static void main(String[] args) 
        throws InterruptedException, ParseException 
    { 
        // Initializing SimpleDateFormat 
        SimpleDateFormat SDFormat 
            = new SimpleDateFormat(); 
  
        // Setting the DateFormatSymbols 
        DateFormatSymbols DFSymbols 
            = new DateFormatSymbols( 
                new Locale("en", 
                           "US")); 
  
        // Illustrating the set method 
        SDFormat.setDateFormatSymbols(DFSymbols); 
  
        // Displaying the formats 
        Date date = new Date(); 
        String str_Date1 = SDFormat.format(date); 
        System.out.println("The SimpleDateFormat: "
                           + (str_Date1)); 
  
        // Working of DFS 
        String[] the_days 
            = DFSymbols.getShortWeekdays(); 
        int i, j = 1; 
        for (i = 1; i < the_days.length; i++) { 
            System.out.print("Day" + j++ + " : "
                             + the_days[i] + "\n"); 
        } 
    } 
}

输出：

The SimpleDateFormat: 1/30/19 10:27 AM
Day1 : Sun
Day2 : Mon
Day3 : Tue
Day4 : Wed
Day5 : Thu
Day6 : Fri
Day7 : Sat

示例2:

// Java code to illustrate 
// DateFormatSymbols() method 
  
import java.text.*; 
import java.util.*; 
  
public class SimpleDateFormat_Demo { 
    public static void main(String[] args) 
        throws InterruptedException, ParseException 
    { 
        // Initializing SimpleDateFormat 
        SimpleDateFormat SDFormat 
            = new SimpleDateFormat(); 
  
        // Setting the DateFormatSymbols 
        DateFormatSymbols DFSymbols 
            = new DateFormatSymbols( 
                new Locale("es", 
                           "XL")); 
  
        // Illustrating the set method 
        SDFormat.setDateFormatSymbols(DFSymbols); 
  
        // Displaying the formats 
        Date date = new Date(); 
        String str_Date1 = SDFormat.format(date); 
        System.out.println("The SimpleDateFormat: "
                           + (str_Date1)); 
  
        // Working of DFS 
        String[] the_days 
            = DFSymbols.getShortWeekdays(); 
        int i, j = 1; 
        for (i = 1; i < the_days.length; i++) { 
            System.out.print("Day" + j++ + " : "
                             + the_days[i] + "\n"); 
        } 
    } 
}

输出：

The SimpleDateFormat: 1/30/19 10:28 AM
Day1 : dom
Day2 : lun
