This application was written as a solution to the Decode the Morse code kata published on the Codewars website.

This application will accept Morse code as a string, input by the user, and return the decoded Morse as a string in Latin script.

This application was written in Java 21 using:

• Object-oriented programming paradigm
• Model–view–controller (MVC) design pattern
• Test-driven development methodology

• Java 21
• Access to command line interface / terminal

1. Download morse-decoder.jar from the /out/artifacts/morse_decoder_jar/ directory of this repository.
2. Move the downloaded file to another local directory on your device of your choosing.
3. Open your command line interface / terminal and navigate to the local location of morse-decoder.jar.
4. Run the application with the following command:

java -jar morse-decoder.jar

Once you have run the application with the command above, you will be shown the following text:

Welcome to the Morse Code Decoder!

Morse code letters must be separated by a SINGLE space and word by a TRIPLE space.

Are you ready to decode morse code? [Y / N] and hit ENTER.

If you are ready to enter the Morse code message to decode, type Y and press the ENTER key. If not, type N and press the ENTER key.

If you selected to continue, you will be prompted to enter the Morse code message:
