在哪里可以找到标准化的美国各州和加拿大各省Java地图，缩写为全名

Question

我需要一本Java字典来查找北美州和省缩写中的完整州和省名称。例如；TX"-->quot；德克萨斯州"NS"-->quot；Nova Scotia"；。

我在这里找到了C#版本：标准化的美国国家阵列和国家阵列

使用Map集合的Java版本是什么？

Answer 1

这是Java字典，将美国州和加拿大省的缩写映射为全名，改编自问题中提到的C#版本。为了简洁起见，它使用了静态初始化。

// the US State and Canada abbreviation dictionary, abbreviation --> full name
private final static Map<String, String>  stateAbbreviationDictionary = new HashMap<>();
static {
// USA
stateAbbreviationDictionary.put("AL", "Alabama");
stateAbbreviationDictionary.put("AK", "Alaska");
stateAbbreviationDictionary.put("AZ", "Arizona");
stateAbbreviationDictionary.put("AR", "Arkansas");
stateAbbreviationDictionary.put("CA", "California");
stateAbbreviationDictionary.put("CO", "Colorado");
stateAbbreviationDictionary.put("CT", "Connecticut");
stateAbbreviationDictionary.put("DE", "Delaware");
stateAbbreviationDictionary.put("DC", "District Of Columbia");
stateAbbreviationDictionary.put("FL", "Florida");
stateAbbreviationDictionary.put("GA", "Georgia");
stateAbbreviationDictionary.put("HI", "Hawaii");
stateAbbreviationDictionary.put("ID", "Idaho");
stateAbbreviationDictionary.put("IL", "Illinois");
stateAbbreviationDictionary.put("IN", "Indiana");
stateAbbreviationDictionary.put("IA", "Iowa");
stateAbbreviationDictionary.put("KS", "Kansas");
stateAbbreviationDictionary.put("KY", "Kentucky");
stateAbbreviationDictionary.put("LA", "Louisiana");
stateAbbreviationDictionary.put("ME", "Maine");
stateAbbreviationDictionary.put("MD", "Maryland");
stateAbbreviationDictionary.put("MA", "Massachusetts");
stateAbbreviationDictionary.put("MI", "Michigan");
stateAbbreviationDictionary.put("MN", "Minnesota");
stateAbbreviationDictionary.put("MS", "Mississippi");
stateAbbreviationDictionary.put("MO", "Missouri");
stateAbbreviationDictionary.put("MT", "Montana");
stateAbbreviationDictionary.put("NE", "Nebraska");
stateAbbreviationDictionary.put("NV", "Nevada");
stateAbbreviationDictionary.put("NH", "New Hampshire");
stateAbbreviationDictionary.put("NJ", "New Jersey");
stateAbbreviationDictionary.put("NM", "New Mexico");
stateAbbreviationDictionary.put("NY", "New York");
stateAbbreviationDictionary.put("NC", "North Carolina");
stateAbbreviationDictionary.put("ND", "North Dakota");
stateAbbreviationDictionary.put("OH", "Ohio");
stateAbbreviationDictionary.put("OK", "Oklahoma");
stateAbbreviationDictionary.put("OR", "Oregon");
stateAbbreviationDictionary.put("PA", "Pennsylvania");
stateAbbreviationDictionary.put("RI", "Rhode Island");
stateAbbreviationDictionary.put("SC", "South Carolina");
stateAbbreviationDictionary.put("SD", "South Dakota");
stateAbbreviationDictionary.put("TN", "Tennessee");
stateAbbreviationDictionary.put("TX", "Texas");
stateAbbreviationDictionary.put("UT", "Utah");
stateAbbreviationDictionary.put("VT", "Vermont");
stateAbbreviationDictionary.put("VA", "Virginia");
stateAbbreviationDictionary.put("WA", "Washington");
stateAbbreviationDictionary.put("WV", "West Virginia");
stateAbbreviationDictionary.put("WI", "Wisconsin");
stateAbbreviationDictionary.put("WY", "Wyoming");
// Canada
stateAbbreviationDictionary.put("AB", "Alberta");
stateAbbreviationDictionary.put("BC", "British Columbia");
stateAbbreviationDictionary.put("MB", "Manitoba");
stateAbbreviationDictionary.put("NB", "New Brunswick");
stateAbbreviationDictionary.put("NL", "Newfoundland and Labrador");
stateAbbreviationDictionary.put("NS", "Nova Scotia");
stateAbbreviationDictionary.put("NT", "Northwest Territories");
stateAbbreviationDictionary.put("NU", "Nunavut");
stateAbbreviationDictionary.put("ON", "Ontario");
stateAbbreviationDictionary.put("PE", "Prince Edward Island");
stateAbbreviationDictionary.put("QC", "Quebec");
stateAbbreviationDictionary.put("SK", "Saskatchewan");
stateAbbreviationDictionary.put("YT", "Yukon");
}

Java 9引入了不可变映射，这里有一个与不可变映射相同的字典：

private final static Map<String, String> stateAbbreviationDictionary = Map.ofEntries(
// USA
