Summary

Add public getter methods to obtain the fields that are used for equality.

Problem

There are descriptions for the instance's locale and patterns, but there is no way to obtain them, other than parsing the String from toString().

Solution

Add two public methods, getLocale() and getPatterns().

Specification

Add the following two methods in ListFormat class:

   /**
     * {@return the {@code Locale} of this ListFormat}
     *
     * The {@code locale} is defined by {@link #getInstance(Locale, Type, Style)} or 
     * {@link #getInstance(String[])}.
     */ 
    public Locale getLocale()

    /**
     * {@return the patterns used in this ListFormat}
     *
     * The {@code patterns} are defined by {@link #getInstance(Locale, Type, Style)} or 
     * {@link #getInstance(String[])}.

     */

    public String[] getPatterns()
