Java中 map.values转换为list或者string[]

map 中values 返回列表，可以将器转化为list

@Testpublic void testMap2List() throws Exception{    Map<String, String> map = new HashMap<String, String>();    map.put("1", "AA");    map.put("2", "BB");    map.put("3", "CC");    map.put("4", "DD");    Collection<String> valueCollection = map.values();    final int size = valueCollection.size();    List<String> valueList = new ArrayList<String>(valueCollection);    String[] valueArray = new String[size];    map.values().toArray(valueArray);}
