Create a jGrasp project called A4 that includes two java files: Roman.java and RomanApp.java Implement class Roman as specified in the UML class diagram above. Pay special attention to the class name, method names, parameter lists, and return types. They all need to match the specification in the UML class diagram. No fields, public methods, or constructors should be added. Notice the underlined operations. This indicates that the methods are static.
Roman Learning Objectives: Use loops to implement repetitive actions Use if-else statements to provide different paths of execution Develop algorithms to produce the desired result Generate random numbers within a specified range + summary ( + printNumeral ( number : int) Description: In this assignment you are going to display numbers as roman numerals, as described in this article.

Pay special attention to the class name, method names, parameter lists, and return types. They all need to match the specification in the UML class diagram. No fields, public methods, or constructors should be added. Notice the underlined operations. This indicates that the methods are static. Roman.java: Method summary: Print the roman numerals that correspond to 1, 5, 10, 50, 100, and 1000 and the permitted subtractive forms (see expected output) The summary should be printed in tabular form and the columns should be left aligned. Use format specifiers to implement the columns and include a larger space to separate the numerals on the left from the subtracted forms on the right. This makes the summary easier to read. Notice that there is no subtractive form in the first line. Method Print Numarati If the number passed to the method is between 1 and 39 (inclusive) print the roman numeral corresponding to the parameter value. Otherwise print: Valid number range: 1 - 39 In order to print numbers as roman numerals, you need to understand how the roman numerals work. Depending on the resource you might find slight variations. For this assignment I want you to use the description provided in this article: http://www.purplemath.com/modules/romannum.htm ( FYI: The article consists of two pages). Resist the temptation to hard-code the numerals for all 39 numbers. Instead look for patterns and use control statements (e.g. if, if-else, loops) to implement this method. Look for patterns that avoid code repetition. Even though it is forbidden to add public methods to the class (it needs to be implemented exactly as specified in the UML class diagram) you are free to add private methods to structure your code. RomanApp.java RomanApp includes the main method and it is a test client for class Roman. Hint: static methods should be called on the type NOT on an instance. In order to test the class Roman do the following: a) Display the summary b) Use a loop to call the method printNumeral repeatedly. Pass the numbers 0 to 40 (inclusive) as argument. After each method call the cursor should be advanced to the next line. Expected Output: I = 1 V = 5 IV = 4 X = 10 IX = 9 L = 50 XL = 40 C = 100 XC = 90 D = 500 CD = 400 M = 1000 CM = 900 Valid number range: 1 - 39 II III IV VI VII VIII IX XI XII XIII XIV XV XVI XVII XVIII XIX XX XXI XXII XXIII XXIV XXV XXVI XXVII XXVIII XXIX XXX XXXI XXXII XXXIII XXXIV XXXV XXXVI XXXVII XXXVIII XXXIX Roman Learning Objectives: Use loops to implement repetitive actions Use if-else statements to provide different paths of execution Develop algorithms to produce the desired result Generate random numbers within a specified range + summary ( + printNumeral ( number : int) Description: In this assignment you are going to display numbers as roman numerals, as described in this article.
