Is there a Util to convert US State Name to State Code. eg. Arizona to AZ?

I know this doesn't answer the question, but just in case someone needs the opposite: to use state/province abbreviations as keys and names as values. It took me a few minutes to reformat the map. Also, the abbreviation for Quebec in the accepted answer is wrong.

public static final Map<String, String> STATE_MAP;
static {
    STATE_MAP = new HashMap<String, String>();
    STATE_MAP.put("AL", "Alabama");
    STATE_MAP.put("AK", "Alaska");
    STATE_MAP.put("AB", "Alberta");
    STATE_MAP.put("AZ", "Arizona");
    STATE_MAP.put("AR", "Arkansas");
    STATE_MAP.put("BC", "British Columbia");
    STATE_MAP.put("CA", "California");
    STATE_MAP.put("CO", "Colorado");
    STATE_MAP.put("CT", "Connecticut");
    STATE_MAP.put("DE", "Delaware");
    STATE_MAP.put("DC", "District Of Columbia");
    STATE_MAP.put("FL", "Florida");
    STATE_MAP.put("GA", "Georgia");
    STATE_MAP.put("GU", "Guam");
    STATE_MAP.put("HI", "Hawaii");
    STATE_MAP.put("ID", "Idaho");
    STATE_MAP.put("IL", "Illinois");
    STATE_MAP.put("IN", "Indiana");
    STATE_MAP.put("IA", "Iowa");
    STATE_MAP.put("KS", "Kansas");
    STATE_MAP.put("KY", "Kentucky");
    STATE_MAP.put("LA", "Louisiana");
    STATE_MAP.put("ME", "Maine");
    STATE_MAP.put("MB", "Manitoba");
    STATE_MAP.put("MD", "Maryland");
    STATE_MAP.put("MA", "Massachusetts");
    STATE_MAP.put("MI", "Michigan");
    STATE_MAP.put("MN", "Minnesota");
    STATE_MAP.put("MS", "Mississippi");
    STATE_MAP.put("MO", "Missouri");
    STATE_MAP.put("MT", "Montana");
    STATE_MAP.put("NE", "Nebraska");
    STATE_MAP.put("NV", "Nevada");
    STATE_MAP.put("NB", "New Brunswick");
    STATE_MAP.put("NH", "New Hampshire");
    STATE_MAP.put("NJ", "New Jersey");
    STATE_MAP.put("NM", "New Mexico");

    STATE_MAP.put("NF", "Newfoundland");
    STATE_MAP.put("NC", "North Carolina");
    STATE_MAP.put("ND", "North Dakota");
    STATE_MAP.put("NT", "Northwest Territories");
    STATE_MAP.put("NS", "Nova Scotia");
    STATE_MAP.put("NU", "Nunavut");
    STATE_MAP.put("OH", "Ohio");
    STATE_MAP.put("OK", "Oklahoma");
    STATE_MAP.put("ON", "Ontario");
    STATE_MAP.put("OR", "Oregon");
    STATE_MAP.put("PA", "Pennsylvania");
    STATE_MAP.put("PE", "Prince Edward Island");
    STATE_MAP.put("PR", "Puerto Rico");
    STATE_MAP.put("QC", "Quebec");
    STATE_MAP.put("RI", "Rhode Island");
    STATE_MAP.put("SK", "Saskatchewan");
    STATE_MAP.put("SC", "South Carolina");
    STATE_MAP.put("SD", "South Dakota");
    STATE_MAP.put("TN", "Tennessee");
