Cannot cast object to hashmap

Question

My code:

Object res =  stub.call(sessionId, "sale.list", "11111");
HashMap<String, String> map = (HashMap<String, String>) res;

Converting object into HashMap i got following exception,

Exception in thread "main" java.lang.ClassCastException: [Ljava.util.HashMap;   
cannot be cast to java.util.HashMap

Can anyone help me how to retrieve object data?

Answer 1

You can cast res to HashMap only if stub.call(sessionId, "sale.list", "11111") returns a HashMap object.

[Ljava.lang.HashMap; indicates that what you are getting is an array of hashMap and not a single HashMap.
