Homework SourseNeed help coding MorseCode in Java Create Class MorseCodeCli
Need help coding MorseCode in Java:
Create Class MorseCodeClient. This represents a Client that allows a user communicate with a server across a network. The server saves the message and then relays the message to another client This is a JFrame application and should extend JFrame and Implement Runnable. The client application should allow the user to type English-language phrases in a JTextArea. When the user sends the message, the client application encodes the text into Morse code and sends the coded message through the server to the other client. Create class MorseCodeClientTest, this is a test class for morse code client and uses the main method to created new instance of MorseCodeClient.
