Example 1:

// Java code to demonstrate setShortMonths()

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.getShortMonths();

        // 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", "DEC",
                             "NOV", "JAN",
                             "FEB" };

        // Setting the default into modified
        format.setShortMonths(modDays);

        // Displaying the modified string
        String[] modifiedDays
            = format.getShortMonths();

        System.out.println("Modified: ");
        for (int i = 0; i < modifiedDays.length; i++) {
            System.out.println(modifiedDays[i] + "  ");
        }
    }
}

        // Displaying the modified string
        String[] modifiedDays
            = format.getShortMonths();

        System.out.println("Modified: ");
        for (int i = 0; i < modifiedDays.length; i++) {
            System.out.println(modifiedDays[i] + "  ");
