Submit the source code .java file(s) on Ecampus under the "Submit Homework" menu option.  It's o.k. to combine the three questions into one compilable java file.
 

1. Create a program named sign.java.  Ask the user which month and day they were born.  Output their birthstone and zodiac sign.  You should have these two methods in your program:
 
String Birthstone(int Month)

String ZodiacSign(int Month, int Day)

Example output:
What month were you born (1-12)? 5
What day of the month were you born? 28

Your birthstone is Emerald.
Your zodiac sign is Gemini.

Extra Credit:  Include the Chinese zodiac animal.  This requires you ask ask the user for the day of the month they were born.

2. Create a program named board.java.  Create a 10x10 two dimensional array of characters.  Fill all 100 elements with a period.  Next, fill ten random elements with a dollar sign.  Place your last name initial in a random location.  Output the array using a nested for loop in this format:

. . . $ . . . . . .
. . . . . . . . . .
. . . $ . . . . . .
. . . . . . . . $ .
. . K . . . . . . $
. . . . . $ . . . .
. $ . . . . . . . .
. . . . . . $ . . .
. . . . . . . . . $
. $ $ . . . . . . .
 

3. Create a program named roman.java.  Ask the user to enter a Roman Numeral.  Output the numeric value of the Roman Numeral.  You should have the following method in your program:  int RomanToDecimal(String R)

Here's some numbers to test your program with:  MCMXLII = 1942, MCMLXIX = 1969, DCCCLXXXVIII = 888

Hint: In the RomanToDecimal method, create a for loop that steps through each character of roman numeral. 

M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, I = 1.  
MDCLXVI = 1000 + 500 + 100 + 50 + 10 + 5 + 1 = 1666

If a digit is out of order, then it is subtracted from the next digit.  This is only used for these combinations:
CM = 900, CD = 400, XC = 90, XL = 40, IX = 9, IV = 4
