Cast Object array to custom class array java

Question

I have an Object array that I am trying to cast to custom "document" class. I have tried following:

 this.documentList = Arrays.copyOf(objectDocumentList, objectDocumentList.length,Document[].class);

And

 for(int i=0;i<this.objectDocumentList.length;i++){
     this.documentList[i]= (Document) objectDocumentList[i];
 }

Answer 1

我使用 Gson "toJson" 函数将我的对象转换为字符串，然后使用该字符串通过网络传递。
