I'm attempting to create a program that acts as a server, and when it gets connections from a client, it sends the text and the client opens a new window and displays the text. I got it to connect and send and everything, but the text says "84" instead of what it's supposed to say. I don't know if that's a problem with the bytes or what. Well, here's my code. I've taken out a few of the non-needed classes.

Server code

JButton disconnect = new JButton("Disconnect");

setLayout(gl);
