    [Homework] month name to 3 letter abbrevation

    Hi all,
    So i've been struggling with this homework that is convert a month to a 3 letter abbreviation. I i've done many searches that month month numbers to names, abbreviations to months etc, but not what I need.

    Here is the number to date from my textbook:

    /** MonthNumbers.java reads a 1-12 number and displays 
     *   the three-letter abbreviation of the corresponding month.
     * @author Joel Adams, for Alice+Java
    import java.util.Scanner;
    public class MonthAbbreviations {
      public static void main(String[] args) {
    	// get the month number
        System.out.println("To see the first three letters of a month,");
        System.out.print(" enter a month-number (1-12): ");
        Scanner kbd = new Scanner(System.in);		
        int monthNumber = kbd.nextInt();
        // compute the month abbreviation
        final String monthTable = "JanFebMarAprMayJunJulAugSepOctNovDec";
        int start = (monthNumber - 1) * 3;
        int stop = start + 3;
        String monthAbbrev = monthTable.substring(start, stop);
        // display the month abbreviation
        System.out.println("\nMonth #" + monthNumber + 
                            " begins with '" + monthAbbrev + "'.");
    I'm wondering if name to abbreviation is similar with a few modifications to this? Thanks in advance for any help.

    Please edit your post and wrap the code in code tags.

    Look at using an array to hold the month names instead of a String that you have to index into.
    name to abbreviation
    Can you give some examples of that. What are the cases where the abbreviation is not just the first 3 letters?
