Instructions: Develop a Java class called RamString that correctly implements the WackyStringInterface that is provided. (The semantics of the methods in the interface should be obvious from their name and from the Javadoc comments in the code. If not, please ask for clarification) The RamString class should be designed so that instance variables are never NULL.

Important note: This project is focused on character and String manipulation and you are not allowed to use regular expressions or any classes or methods that make us of regular expressions.

Write a test driver for class RamString called RamStringTester. Specifically, you should create several different test cases for each method of in the interface. Each test should be a separate method. Make sure that the tests are not trivial (i.e., have a specific purpose). In other words, each test should (1) test a specific piece of functionality and (2) check that such piece of functionality behaves as expected. In addition, at least two of the tests for method convertDigitsToRomanNumeralsInSubstring should result in expected exceptions: MyIndexOutOfBoundsException (provided) in one case, and IllegalArgumentException in the other.

Add a concise comment to each test that you implement to clarify its rationale (e.g., "This test checks whether method convertDigitsToRomanNumeralsInSubstring suitably throws an IllegalArgumentException if startPosition is greater than endPosition"). Please note the tests you are creating are not Junit test cases. It is expected that all tests defined in the RamStringTester class will be called in its main method and the output of each test printed to the console.

Notes:

You cannot modify the provided interface, WackyStringInterface.
You must use the provided MyIndexOutOFBoundsException class
I will run your code against a standard set of test cases to make sure that you implemented the functionality of the required methods correctly.
Comment out or remove any package statements from the files that you submit to Blackboard.

Write this program in JAVA and compile it in JDK 8 or better. Follow all commenting conventions discussed in class and include a comment block at the top of each file with your name, date, the course number and section. In addition, the comment block at the top of the tester class must include a description of the program purpose, input, and output. It is expected that your program will be well documented and you are required to include a private helper method in your driver called printHeading that outputs the following information to the console in an easy-to-read format: your name, the project number, the course identifier, and the current semester. You will call this method as the first statement in your main method.
