Javascript - How to create an object array?

Question

I want to know if it is possible to declare an array in Javascript of the type "com.peregrine.servicecenter.PWS.Common.MessageType". In java it is easy but in javascript I have not idea. Thanks.

Check out this thread; it basically asks the same question: stackoverflow.com/questions/881515/… — Jeff

Is your question really "How do I declare something in JavaScript that is an instance of a particular Java class?" You do understand that Java and JavaScript are separate languages? — nnnnnn

I've never worked with namespaces but I'm going to read about it, thanks. — user807623

Yes, I know they are separate but the question is about if you can "simulate" a java class array in Javascript. Thanks — user807623

@nnnnnn Java is to JavaScript as Car is to Carpet. :-) (I know you know the difference user, but I couldn't help it) — cwallenpoole

sure it's possible:

var myArray = [];

remember that javascript is not a statically typed language, so you don't need to declare an array of a specific type.... just an array. Now, given the type you're referring to, I don't think that's exactly what you're asking though...

No, it is not possible. The Array in JS doesn't care what you've put in it, or even that the array indexes are numeric. Java, on the other hand, requires strict typing of both. I'd even go so far as to say that even Object[] is a completely different paradigm from [].

You cannot declare an array to exclusively consist of a particular type. However, you can declare an array (var myArray = [];) and you can add objects of your intended type to it (myArray.push(myMessageType);).

You can declare the array in such a way.

 var arr = [];

it can contain object or array of object by calling

 arr.push(x)

I tried that before but it still is a non type array. Thank you anyway.
