Keeping socket connections in an Array and using them - Java

Is it possible to keep each incoming socket connection in an array and use each whenever we need in Java?

I tried the following Array structure but it throws Exception in thread "ServerHandler-0" java.lang.ArrayStoreException: java.net.Socket

My array looks like this:

 Object[][] requests;

And i insert objects into th开发者_如何学JAVAis as follows:

 requests[position][0] = o; //o is a Serializableobject
 requests[position][1] = s; // this is the socket instance

My intention is to use a socket pulled from the array:

Socket s = (Socket) requests[position][1];
OutputStream os = s.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(os);
oos.writeObject(o);

thanks.

To get rid of the ArrayStoreException I would create a Request-class which holds the information and then store the Request in the array. This way you don't need to do a lot of unnecessary casting and don't need to use Object as the type of the array. I can also recommend you to have a look at java.nio where you use channels and selectors to choose desired sockets, which I think is what you are trying to do.

Have you initialized requests[position] to new Object[2]?
