对Map开展循环

对Map进行循环
Map<String, String> gameInfo

for (String key : gameInfo.keySet()) {
                if (key.equalsIgnoreCase(code)) {
                    return gameInfo.get(key);
                }
            }

---------------------------
String[] 转 List
        ArrayList<String> codeList = new ArrayList<String>();
        int k = codes.length;
        if (codes != null) {
            for (int i = 0; i < codes.length; i++) {
                if (!codes[i].equals("")) {
                    codeList.add(codes[i]);
                }
            }
        }
