CMCS204- Assignment 5- Morse Code Converter Utility Solved
Samuel F. B. Morse produced the first working telegraph set in 1836. This made transmission possible over any distance. The first Morse Code message, "What hath God wrought?", was sent from Washington to Baltimore.
Morse code was extensively used for early radio communication beginning in the 1890s.
In the early part of the twentieth century, the majority of high-speed international communication was conducted in Morse code, using telegraph lines, undersea cables, and radio circuits.
Morse code can also be transmitted using light which sometimes happens between ships at sea. It is used in emergencies to transmit distress signals when no other form of communication is available. The standard international distress signal is •••---••• (SOS).
Assignment Description
Write the classes required to create a Morse Code Converter Utility. Your Morse Code Converter Utility will be using a generic linked binary tree with generic TreeNodes to convert Morse Code into English. There is no GUI requirement for this assignment. You are supplied a GUI for testing purposes.

Building a Tree for conversion purposes
Data Element - TreeNode class
This generic class is used in the MorseCodeTree classes. The class consists of a reference to the data and a reference to the left and right child. Follow the Javadoc that is provided. The Javadoc only lists those public methods that are required to pass the Junit tests. You may add any private methods you need for your design.
Data Structure - MorseCodeTree class
A generic linked binary tree which inherits from the LinkedConverterTreeInterface. The class uses an external generic TreeNode class parameterized as a String: TreeNode<String. This class uses the private member of root. Nodes are added based on their morse code value. A ‘.’ (dot) means to traverse left and a ‘-‘ (dash) means to traverse right. The constructor will call the method to “build the tree”. Follow the Javadoc that is provided. The Javadoc only lists those public methods that are required to pass the Junit tests. You may add any private methods you need for your design.
Utility class - MorseCodeConverter
The MorseCodeConverter contains a static MorseCodeTree object and constructs (calls the constructor for) the MorseCodeTree.
This class has two static methods convertToEnglish to convert from morse code to English. One method is passed a string object (“.-.. --- ...- . / .-.. --- --- -.- ...”). The other method is passed a file to be converted. These static methods use the MorseCodeTree to convert from morse code to English characters. Each method returns a string object of English characters.
There is also a static printTree method that is used for testing purposes – to make sure the tree for MorseCodeTree was built properly.
Use the Javadoc provided to make sure that your MorseCodeConverter class follows the method headers so that the MorseCodeConverterTest will run correctly.
Testing - JUnit Test Classes
You must add at least 1 test for MorseCodeConverter.convertToEnglish(String) and at least 1 test for MorseCodeConverter.convertToEnglish(File) to the MorseCodeConverterTest class. You must create a JUnit test for your MorseCodeTree class. Include your test files with your code files.
Assignment Details
This is a table for the conversion from Morse Code to alpha letters.
Building the MorseCodeTree (method buildTree)
Your MorseCodeTree is a 4 levels tree. Insert a mapping for every letter of the alphabet into the tree map. The root is a TreeNode with an empty string. The left node at level 1 stores letter ‘e’ (code ‘.’) and the right node stores letter ‘t’ (code ‘-‘). The 4 nodes at level 2 are ‘i’, ‘a’, ‘n’, ‘m’ (code ‘..’, ‘.-‘, ‘-.’, ‘—‘). Insert into the tree by tree level from left to right. A ‘.’ will take the branch to the left and a ‘-‘ will take the branch to the right. This is the structure of the tree.
Using the MorseCodeTree
Use the MorseCodeTree to convert Morse Code to English by taking the code and finding it’s corresponding English letter by traversing the MorseCodeTree, ‘.’ branches to the left and ‘-‘ branches to the right. The code ‘.--.’ would branch to the left, then to the right, then to the right, then to the left to Fetch the letter ‘p’. Each letter is delimited by a space (‘ ‘). Each word is delimited by a ‘/’.

1. There is a morse code translator at:

2. Morse code (Wikipedia)

Write-up & Submission Requirements
Review the provided rubric to understand project expectations, including documentation, CMSC204, and programming requirements. Two artifacts MUST be submitted for this project: Java source code and a write-up.
At a minimum, the write-up needs to address -
Approach, design & algorithm
DO NOT start coding your project immediately! Come up with a high level design for the project first
What’s your game plan to complete the project?
Break the project into smallest modules where applicable
UML diagrams will go a long way
Each student is welcome to expand on the design, if it makes sense. Students will not be penalized for going “above and beyond” specifications of the project
Complete this step first, then write your code
Test Plan & Test Cases
Ensure that your project can successfully pass all provided “public test cases.” What other test cases have you attempted?
Students should think about potential private tests – what would they be?
Your instructor will test your project using an additional set of private test cases as well as the provided public test cases
o I want to see your “thinking,” in particular, how you are testing your program
o Each submission should be rock solid, with no bugs
Capture screenshots of your test runs in your write-up as you run them
Highlight your learning experience and lessons learned
I am very interested to learn about what you have done, how you did, etc.
Anything else that you want to share with me
· Take a screen shot of the repo with the directory and files
If your project is not working as expected, submit it as-is but clearly articulate your situation in your write-up in order to potentially receive partial credit
