CPS 150/Spring 2017
Assigned: February 13.
Instructor: Tamisra H. Sanyal Assignment 1
Due: February 20, 11 pm. Restaurant Check Calculator
Cutoff: February 23, 11 pm Objectives: Basic programming involving arithmetic, input, and output, output formatting, named constants, modular
programming using methods.
Functionality
A restaurant patron orders a drink, an appetizer, a main dish (entrée), and a dessert. This program would take the cost
information for each item from the user and calculate the total amount to be paid by the customer, including the sales
tax to be charged (at 7.25%) and tips. The program would also suggest how much the tip should be (at levels of 15%,
18%, 20% of total of food costs, not including the tax). The program would then ask how much tip the customer actually
wishes to pay. This last value would then be used to display the total amount the customer should pay.
Program input/output
The program should ask for the prices of each item the customer ordered. It would then show the suggested tip
amounts at various levels and ask how much tip the customer wants to pay. It would then show the final output (a
restaurant check), itemizing total food cost, sales tax, tip and the total due from the customer. It would include the
name of the restaurant (defined as a named constant). See sample output. Use System.out.printf for formatted
output. Choose a nice name for your restaurant. The sales tax rate should be defined as a named constant.
The output from the program has two clear sections: The dialog with the user, and the displayed/printed check. These
two sections should be separated by a horizontal line (a bunch of hyphens).
Program Structure
This is essentially a straight-line input-process-output (IPO) program, but you should break up the code into methods
(similar to the sample program BasicIPOModular.java). All these methods will accept no parameters. The main method
will do the following in sequence:
1. Print the output identification line – CPS 150 Assignment 1 by your name
2. Call a method to get server's first name, prices for drink, appetizer, entrée and dessert
3. Calculate the total cost of the food items (no need to call a method, this is just one statement)
4. Call a method to calculate and print the tip suggestions at 15%, 18%, and 20%.
5. Call a method to prompt for and get the tip actually paid by the customer (you could reuse a method from
BasicIPOModular2.java).
6. Call a method to calculate the Sales tax (7.25% of the total food price not including the tips) and the total due
from customer (= total food price + sales tax + tips).
7. Call a method to print the restaurant check separated from the user interaction by a line of hyphens, the check
should be nicely formatted, as in the sample output.
8. Print the sign-off line – Assignment 1 complete
You may use the methods that combine prompting and getting input values from BasicIPOModulr2.java.
Program style requirements
You should declare the variables and named constants at the class level, including the Scanner created on System.in
when these are shared by methods. But any variables/constants used in only one method, such as for calculating the
suggested tip amounts, should be declared as local identifiers within that method.
To get full credit for the assignment, you must do the following:
• Use variable/constant/method names that are meaningful
• Header block comments and sections comments should be given
• Program text should be easy to read and nicely formatted (NetBeans can help with Source-> format)
• Program output should be easy to read and well –organized.

You will need to submit a Microsoft word document containing your source code and the screen shot. See the document
"How to submit assignments" posted on Isidore.
Note
You can use the following method for rounding a value to two digits after decimal point. This should be done with all
money calculations that may have a result with > 2 digits after decimal point (Sales tax and total due).
static double round2(double d) {
return Math.round(d * 100) / 100.0;
}
