我在哪里可以找到标准化的美国和加拿大省Java Map，全名的缩写 [英] Where can I find a standardized US States and Canadian Provinces Java Map, abbreviations to full names

问题描述

我需要一个Java词典来从北美州和省的缩写中查找州和省的完整名称.例如，"TX"表示->得克萨斯州"，"NS"州->新斯科舍省".

I need a Java dictionary to look up full state and province names from North American state and province abbreviations. For example, "TX" --> "Texas", "NS" --> "Nova Scotia".

我在这里找到了C#版本:标准化的美国州阵列和国家数组

I found the C# versions here: Standardized US States Array and Countries Array

使用Map集合的Java版本是什么?

What is the Java version using the Map collection?

推荐答案

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

Here is the Java dictionary, mapping US state and Canadian province abbreviations to full names, adapted from the C# versions mentioned in the question. It uses static initialization for brevity.

// 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，这是实现为不可变映射的同一词典:

Java 9 introduced immutable maps and here is the same dictionary implemented as an immutable map:

// the US State and Canada abbreviation dictionary, abbreviation --> full name
  private final static Map<String, String> stateAbbreviationDictionary = Map.ofEntries(
          // USA
          entry("AL", "Alabama"),
          entry("AK", "Alaska"),
