Question

** This is the Client Side of my server/client socket program.

** I need help coding the send button, that will send messages to the server and display them in the text area of the GUI using "output.append("Client: UserInput"); The send button action performed is below in bold, and where the Client will input the message is right above it.

** this program is created on Netbeans IDE 8 using Java

Below is the code for my GUI

import java.net.*;
import java.io.*;

/**
* Creates new form KnockKnockClient
