Question
Create a program based on a UML Class Diagram.
Software Requirements:
Latest version of Netbeans
Java Development Kit (JDK) 8
Procedure:
1. Create a folder named LastName_FirstName (ex. Reyes_Mark) in your local drive.
2. Create a project named LabExer2. Set the project location to your own folder.
3. Construct a simple purchasing program based on the UML Class Diagram below.
LabExer2
itemName: String
itemPrice: double
itemQuantity: int
- amountDue: double
+ setltemName(String newltemName): void
+ setTotalCost (int quantity, double price): void
getltemName(): String
+ getTotalCost(): double
readinput(): void
+ writeOutput(): void
Note: The readinput() method will be used to accept user input through the Scanner class. This is
done by:
a. Writing import java.util."; on top of the code, before the line for the class name
b. Instantiating an object of the Scanner class, Scanner s = new Scanner (System.in);
c. Storing the input to the variable name based on data type
For String:
For int:
For double:
s.nextLine()
s.nextint()
s.nextDouble()
The writeOutput() method will be used to display an output similar to the sample below.
You are purchasing 3 bag(s) at 1,745.5 each.
4. Inform your instructor once you are done.
Sample output:
Enter the name of the item you are purchasing.
bag
Enter the quantity and price separated by a space.
3 1475.50
