How to serialize OBJECT ARRAY in java?

Question

I have an OBJECT ARRAY, how can i serialize this array? I give you c# code and i have to write in java. Thanks. C#:

byte[] data = JSon.Serialize<object[]>(Parameters);

Please note that i want to serialize an array which has objects.. i realize that is not the exact answer:

ObjectOutputStream out = new ObjectOutputStream(anyOutputStream);
out.writeObject(objectArray);

i have a problem with anyOutputStream, i really don't know what i should place on parameter..

I think it's already answered here: http://stackoverflow.com/questions/4262390/how-to-serialize-json-object-in-java — DaMachk, Jul 31 '13 at 10:12
Use any of the existing JSON API's, for example [Jackson](http://wiki.fasterxml.com/JacksonInFiveMinutes) — fvu, Jul 31 '13 at 10:14

If the object array contains Serializable objects then you can use java.io.ObjectOutputStream

ObjectOutputStream out = new ObjectOutputStream(anyOutputStream);
out.writeObject(objectArray);

i have this error message: The constructor JSONObject(Object[]) is undefined, any idea? – patronaviera Jul 31 '13 at 10:34
Clearly, you need a `JSONArray` if you're going to serialize an array. However, there's no guarantee it will work---it all depends on what the framework can do with your array elements. – Marko Topolnik Jul 31 '13 at 11:25
