Question

I was wondering if there exists a similar functionality in Java similar to C#’s anonymous types:

var a = new {Count = 5, Message = "A string."};

Or does this concept go against the Java paradigm?

EDIT:

I suppose using Hashable() in Java is somewhat similar.

Maybe you mean sth like this:

Object o = new Object(){
    int count = 5;
    String message = "A string.";
};

@Commenters: of course this is a theoretical, very inconvenient example.

Probably OP may use Map:

Map<String,Object> a = new HashMap<String,Object>();
a.put("Count", 5);
a.put("Message", "A string.");

int count = (Integer)a.get("Count"); //better use Integer instead of int to avoid NPE
String message = (String)a.get("Message");
