Need help coding MorseCodeServer in Java

Create Class MorseCodeServer which represents a multithreaded server application This class maintains morse code for two clients MorseCodeClient. This first version should just relay the morse code from one client to the other. This server does not need to have a Graphical interface. You will most likely need to import all of the following classes into your server. Create class MorseCodeServerTest, this is a test class for morse code server. It creates an instance of MorseCodeServerTest.

Solution

encodeMorse = new TreeMap<>(); decodeMorse = new TreeMap<>(); // Create encode and decode Maps for(int i = 0; i < characters.length; i++) { encodeMorse.put( characters[i], codes[i]); decodeMorse.put( codes[i], characters[i]); } } // end Client constructor // connect to server and process messages from server public void runClient() { Boolean socketConnected = false; try // Connect to server, get streams, process connection { // If socket creation is successful.
