Deliverables

Your project files should be submitted to Web-CAT by the due date and time specified above (see the Lab Guidelines for information on submitting project files).  In order to avoid a late penalty for the project, you must submit your completed code files to Web-CAT by 11:59 PM on the due date. You may submit your project up to 24 hours after the due date, but there is a late penalty of 15 points.  No projects will be accepted after the one day late period. If you are unable to submit via Web-CAT, you should e-mail your project Java files in a zip file to your TA before the deadline.

Files to submit to Web-CAT:

• java
• java

Specifications

Overview: You will write two programs in this project.  The first will calculate the minimum number of paper currency denominations (twenties, tens, fives, and ones) in a specified number of dollars, and the second will calculate the result of formula for inputs x, y, and z.

• ATM.java

Requirements: A bank would like to have a program for its ATM department that allows the user to enter a value in whole dollars and then displays the combination of twenties, tens, fives, and ones such that each denomination is maximized in order by twenties, tens, fives, and ones. The input value should not exceed 500 dollars.

Design: The bank would like the output to look as shown in the examples below where 12345 is entered as the input for one run and 399 is entered for another run.

Your program must follow the above format with respect to the output.  Note that lines 3 through 6 for the input value of 399 begin with tab which is equivalent to three spaces in jGRASP (i.e., your output should use the escape sequence for a tab).

Code: In order to receive full credit for this assignment, you must read in a value and store it in a variable of type int, calculate the number of each denomination (twenties, tens, fives, and ones) and store each value in a variable of type int. It is recommended as a practice that you do not modify any input values once they are stored. Your expressions should contain only int variables or int literals. Commas are not allowed in Java numeric literals (e.g., 1000 may be entered as 1000 or 1_000).

Test: You will be responsible for testing your program, and it is important to not rely only on the example above. The amount entered can be any valid int value.  Consider testing with the input values for which it is easy calculate the number of twenties, tens, fives, and ones.

• FormulaCalculator.java

Requirements: A program is needed that inputs values for x, y, and z and calculates a result for the indicated formula.  If the product of x, y, and z is zero, the result is zero.

Design: The result should be calculated as follows:

2𝑥 − 7.4 4𝑦 + 9.3        (6𝑧 − 11.2)

𝑟𝑒𝑠𝑢𝑙𝑡 =                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   for          xyz

𝑥𝑦𝑧

Special case:

𝑟𝑒𝑠𝑢𝑙𝑡 = 0                                                                                                                                                                                                                                                                         for          xyz =    0

Three examples of program output for the indicated input values are shown below.  Note that lines 2 through 4 for the input values begin with tab which is equivalent to three spaces in jGRASP (i.e., your output should use the escape sequence for a tab)

    Example #1

                 Example #2

Example #3

Code: Your numeric variables should be of type double.  Use an if-else statement to determine if the divisor in the formula is zero. Note that in Example #2, the value of x is zero so the divisor evaluates to zero.

Test: You are responsible for testing your program, and it is important to not rely only on the examples above. Remember that the input values are doubles, so be sure to test both positive and negative values (with and without a decimal point) for x, y, and z.  You should use a calculator or jGRASP interactions to check your answers.
