java.net.SocketOutputStream cannot be cast to java.io.DataOutputStream

I built a proxy server processing data for MineCraft.

The proxy program works by itself, and I was able to use it to transfer connections to websites or Minecraft servers. Both worked without issue.

However, now I am trying to read the packets, and it requires that I turn the java.net.SocketOutputStream into a Java.io.DataOutputStream.

Casting does not work, nor does:
to = new DataOutputStream(outgoing.getOutputStream()); // throws the error in the title.

I'm very skilled in C#, but just learning Java. how can I convert this stream? - I'm presuming I just need to know the right casting path though another layer/command.

OutputStream is for writing like say in this example:

PrintStream printStream = new PrintStream(socket.getOutputStream());
printStream.print("JOIN #channel1\r\n");
printStream.flush( );
printStream.print("JOIN #channel2\r\n");
printStream.flush( );

Please, elaborate on what you want to achieve

Ah, thanks for the clarification.

I have a java.net.Socket, and the object I'm using is expecting java.io.DataOutputStream.

I have no idea why I was getting that error before, but it does appear to be working now. There must have been another part that was affecting it, part of the code I didn't post. But most of it is changed now, so I won't be able to figure out what the problem was.

Thanks for your help.
