示例1 :

// Java code to demonstrate setMonths()  import java.text.DateFormatSymbols;import java.util.Locale;  public class DateFormat_Main {    public static void main(String args[])    {          // Initialising DateFormatSymbols object        DateFormatSymbols format            = new DateFormatSymbols(                new Locale("en", "US"));          // Taking the default short weekdays        String[] Days = format.getMonths();          // Displaying the original        System.out.println("Original: ");        for (int i = 0; i < Days.length; i++) {            System.out.println(Days[i] + "  ");        }          // Taking an alternative names with        // additional random strings        String[] modDays = { "GEEK", "FOR",                             "GEEK", "DECEMBER",                             "NOVEMBER", "JAN",                             "FEB" };          // Setting the default into modified        format.setMonths(modDays);          // Displaying the modified string        String[] modifiedDays            = format.getMonths();          System.out.println("Modified: ");        for (int i = 0; i < modifiedDays.length; i++) {            System.out.println(modifiedDays[i] + "  ");        }    }}

输出:

Original: January  February  March  April  May  June  July  August  September  October  November  December  Modified: GEEK  FOR  GEEK  DECEMBER  NOVEMBER  JAN  FEB
