接受任何类型的数据类型的参数

I have this code:

我有这个代码:

public static Map buildMap(Map map){
    Map data = new HashMap();
    Map mapStorage = new HashMap();

    Set<Map.Entry<String, Class<?>>> entryset = map.entrySet();
    for (Map.Entry<String, Class<?>> entry : entryset) {
        String key = entry.getKey();
        Class<?> val = entry.getValue();
        if(key.contains("_")){
            String mapName = key.substring(0, key.indexOf("_"));
            String mapKey = key.substring(key.indexOf("_")+1, key.length());
            Class<?> mapValue = val;
            boolean mapFound = false;
            Set<Map.Entry<String, Map>> entryset1 = mapStorage.entrySet();
            for (Map.Entry<String, Map> entry1 : entryset1) {
                String key1 = entry1.getKey();
                Map val1 = entry1.getValue();
                if(key1.equals(mapName)){
                        val1.put(mapKey, mapValue);
                        mapFound = true;
                }
            }
            if(!mapFound){
                Map m = new HashMap();
                m.put(mapKey, mapValue);
                mapStorage.put(mapName, m);
            }
        }else{
            data.put(key, val);
        }
    }

    Set<Map.Entry<String, Map>> entryset2 = mapStorage.entrySet();
    for (Map.Entry<String, Map> entry2 : entryset2) {
        String key = entry2.getKey();
        Map val = entry2.getValue();
        data.put(key, val);
    }

    return data;
}
