java - Java中的URLDecode用于命名列表

Question

我需要解码（URLDecode.decode）命名列表中的每个对象。我尝试通过命名列表进行迭代

 for (NamedList nlst : allLists) {
  try {
Namedlist temp =(NamedList) UrlDecode.decode(nlst.toString(),"UTF-8");
}

但它不允许我投进一个命名列表。

请让我知道如何实现这一点。

You cannot cast a String to custom defined class. Think about this way what you are going to do if you want to cast an Integer instance to a String, you will probably use static factory method valueOf() to convert Integer to a String rather than casting it.

So a workaround here is to provide your own static factory method in something like XXXUtil.java

public static NamedList valueOf(String s){
//TODO convert string to namedlist
}
