COIT11222, 2019 Term One - Page 1 of 11 Programming Fundamentals COIT 11222 Assessment item 1—Java Console Program Due date: Week 6 T119 – Midnight, Friday 26 April 2019 Refer below for complete assessment item 1 requirements (Assignment One) ASSESSMENT Weighting: 20% 1 Length: N/A Objectives This assessment item relates to the unit learning outcomes as in the Unit Profile. Details For this assignment, you are required to develop Java Console Programs to demonstrate you can use Java constructs including input/output via a command line and using GUI dialogs, Java primitive and built-in data types, Java defined objects, selection and looping statements, methods, and various other Java commands. Your program must produce the correct results. You are only allowed to use techniques which have been covered in the first five weeks of the subject and within the assignment literature, you must use a Scanner object for console input and no advanced data structures like arrays will be used. What to submit for this assignment The Java source code: You will be able to complete the assignment in weekly parts in which you will produce five java source files. (More details below) Week1.java, Week2.java, Week3.java, Week4.java and Week5.java. Once you have completed all of the programs and you are ready to submit, compress all source files into a single zip file for submission, do not include your report in the zip file. Only submit a zip not a rar file. It is important the file names are correct. o Ass1.zip Also submit a report including, how long it took to create the programs (approximately), any problems encountered and screen shots of the output produced. (Use Alt-PrtScrn to capture just the console window or your dialogs and you can paste them into your Word document) You should test every possibility in the program and annotate your test screen shots. o ReportAss1.docx COIT11222, 2019 Term One - Page 2 of 11 You will submit your files by the due date using the “Assignment 1 Submission” link on the Moodle unit website in the Assessment Block or in the relevant week. Assignment specification This assignment will require you to write small five programs, do not panic! They will be small programs which will cover the first five weekly topics. Usually students were required to write one largish program to demonstrate the topics for the first five weeks. Students get themselves into trouble when the first assignment is due as they have not practiced the basics skills necessary to complete the assignment. With the assignment divided into five programs you can complete each question as we cover the weekly topics, do not let yourself fall behind. General Instructions Each program must contain a header comment which contains: Your name and student number, the name of the file, the date and a brief description of the purpose of the program: // Programmer: Eric Gen S01234567 // File: Week1.java // Date: April 26 2019 // Purpose: COIT11222 assignment one question one T119 // Use println method to print initials using asterisks All programs will be aligned and indented correctly, and contains relevant comments for declarations and statements. All variables and objects will be declared with a meaningful name and use lowercase camel notation: String customerName; All coding will be contained within a main method except for question five when a method will be created and used. For this assignment you will not worry about checking numeric ranges or data types. Refer to a Java reference textbook and the unit material (available on the unit WEB site) for further information about the Java programming topics required to complete this assignment. Check the marking guide (last page) to ensure you have completed every task. You need to match all output exactly as the sample screenshots shown below. Distance and Melbourne students can email questions directly to me, other campus students should seek help from your local tutor, and you can still contact me if it is urgent, I usually respond to emails very promptly. Good luck --- Bruce McKenzie COIT11222 unit coordinator term 1 2019
[email protected] COIT11222, 2019 Term One - Page 3 of 11 Question one (week one topic). Writing output to the screen. Once you have written your first “Hello World” program you will be able to complete question one. Implementation Create a class called Week1 (file: Week1.java) and within it a main method. Use the command System.out.println(""); to print out the first initial of your first and last names as a matrix of asterisks. For example this is my first and last initials printed. The first line of asterisks is printed with this command: System.out.println("****** * *"); You may need to use some graph paper to plot where you need to print your asterisks. If you like you could submit a picture. An attempt at Mickey Mouse! Just do your initials as it takes a while to create a picture. COIT11222, 2019 Term One - Page 4 of 11 Question two (week 2 topics) Input of data types and arithmetic expressions Rocky Dry Cleaners program Rocky Dry Cleaners are requesting a program which allows staff to input a customer’s name and the number of plain garments to be dry cleaned. For simplicity we are only considering plain garments which include shirts, trousers, dresses and jackets etc. The program will compute the cost of the order at $8.50 per garment, you should store this value as a constant. This program will prompt for and read in a customer name using a Scanner object. The customer name will be stored in a String object. The program will then output the customer name in a prompt to read in the number of garments to be cleaned (as a whole number i.e. an integer). Finally the program will display the receipt for the customer. You need to replicate the output exactly as shown below, including the correct line spacing. Implementation Create a class called Week2 (file:Week2.java) and within it a main method as per question one. Import the Scanner class i.e. import java.util.Scanner; Within your main create two Scanner objects named inText and inNumber. One for reading text and the other for reading the numbers, it does not really matter here to have separate Scanner objects but there will be problems later when reading a series of text and numbers (see text pg 77 or pg 81 8th edition). Create a prompt using System.out.print(); To ask the user for the customer name. Declare a String object customerName to store the customer name and use your inText Scanner object and the inbuilt method inText.nextLine(); The customer name is now stored in the String object customerName. COIT11222, 2019 Term One - Page 5 of 11 We can now create a prompt using the customer name to ask for the number of garments to be cleaned Hint: you can join variables and strings using the concatenation operator + "Enter the number of garments for " + customerName + " ==> " Declare an integer variable to store the number of garments and use your inNumber Scanner object and the inbuilt method inNumber.nextInt(); to read the number of garments. Declare a double variable to represent the charge for the order. The arithmetic expression to calculate the total charge is very simple: charge = number of garments * charge per garment Note: the charge per garment must be stored as a constant (use the final keyword). Finally output a receipt for the order as per the sample above. The total charge must be displayed to two decimal points use printf and a format string as follows: System.out.printf("$%.2f", charge); Question three (week three topics) Decision statements The management of Rocky Dry Cleaners would like to encourage customers to get more garments dry cleaned and to possibly get new customers. It has been decided to offer as a special, three garments to be dry cleaned for $20.00 which would be a saving of $5.50 and any subsequent garments in the order would be $6.50 per garment. In summary: One to two garments: $8.50 per garment. Three garments: $20.00. More than three garments: $20.00 plus $6.50 per garment after that. Create a class Week3 (file: Week3.java) and a main method and copy your code from question two into the main method of week three main. After you have read the relevant details of the order i.e. name and number of garments, you will have to create a series of if – else if statements to calculate the final charge. For over three garments; charge = three garments charge + (number of garments – 3) * charge over three When you have calculated the total charge output a receipt as you have done in week two code. Note: you must use constants for all the numeric literals in the else if statements. Your output needs to match exactly the output as shown below. COIT11222, 2019 Term One - Page 6 of 11 COIT11222, 2019 Term One - Page 7 of 11 Question four (week four topics) Repetition while and for loops Create a class Week4 (file:Week4.java) to demonstrate the use of a repetition statement. Implementation Using your solution to question three and a while or for loop, repeat the entry of customer names and the number of garments N times where N is the largest digit in your student ID, if your largest digit is less than three then let N = 3. Hint: use N = 3 while testing and submit using the correct N value. N will be declared as an integer constant using the final keyword. You are to print a title before the input of the customer names and number of garments (see sample output). Note the different line spacing. You will also number the customer in the customer name prompt. Ensure you are using a separate Scanner objects for reading numbers and text (why?). When all of the customer names and number of garments have been entered and their individual charges calculated, the
