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 dass. 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 You are purchasing 3 bag (s) at 1475.5 each. Amount due is 4426.50
