Question

I need this before the end of the day and in java please :)

10.12 Lab 9

In BlueJ, create a project called Lab9

A car dealership pays their salesmen a base salary every month. However, based on how many cars they sold (qtySold) they get a percentage of their salary as a bonus. To determine the percent bonus, the company uses the following chart.

qtySold	%Bonus
5 or less	0%
More than 5 but 10 or less	5%
More than 10 but 15 or less	10%
More than 15	15%

Create a class called Employee as described in the following UML

Employee
- lastName: String - qtySold: int - basePay: double
+Employee() +Employee(name: String, qtySold: int basePay: double) +setLastName(name: String):void +setQtySold(qtySold: int):void +setBasePay(basePay: double): void +getLastName(): String +getQtySold: int +getBasePay(): double +computePercentBonus(): int +calculatePay():double

NOTE: test methods as you implement them

• Constructor with no arguments – does nothing – open and close brace
• Set methods (mutators) set the field to the new values passed in to it
  • setLastName – sets field to the value passed in
  • setQtySold – checks the formal parameter – if it’s negative, it sets the field to zero otherwise it sets the field to the formal parameter
  • setBasePay – checks the formal parameter – if it’s negative, it sets the field to zero otherwise it sets the field to the formal parameter
• Constructor with arguments
  • Calls the set methods to set the fields
• Get methods (accessors) return the field that the get refers to
• computePercentBonus – determines the bonus based on the description above and returns the percent bonus (as an integer – 0, 5, 10, or 15)
• calculatePay – calculates the pay. It will have to call the computePercentBonus method to determine how much bonus to add to the base pay.

Create a text file using notepad. Save the text file in your Lab9 project folder and call it empData.txt. Copy the data below into the file. Save the file.

Tetzner 7 425.85
Martin 3 530.90
Smith 20 470.45
Jones 12 389.74
Glembocki 10 412.74 

Create a class called Main

• The main method should set up a scanner object so it will read the file you just created
• Remember to include the following imports

import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;

• Make sure you test the file when you open it – if it doesn’t find the file it should print an error message to the screen and exit the program
• Print the header to the screen using the following line of code. (you can just copy it) Take notice of the formatting. If you don’t understand what the numbers mean, ask.

System.out.printf("%-10s%8s%10s%8s%12s%n",  "Name","Qty Sold","Base Pay","%Bonus","Total Pay");

• Write a loop that reads in the name, quantity, and base salary from the file and puts the information into an object. It then uses the object to print the line of code (using the get methods) as seen on the output. (use formatting in the header above as an example of how to line up the columns)
• After you get the employees printing out, add the code to your loop to find the total amount paid and the top seller’s number of cars sold for the week and print them out as shown in the output below.

When you are done, upload the Employee class and the Main class to zybooks and submit it.

Sample Output

Name      Qty Sold  Base Pay  %Bonus   Total Pay
Tetzner          7    425.85       5      447.14
Martin           3    530.90       0      530.90
Smith           20    470.45      15      541.02
Jones           12    389.74      10      428.71
Glembocki       10    412.74       5      433.38
The company paid out a total of $2381.15 this week
Top seller this week sold 20 cars 

Answer 1

Note :

We have to paste the input file in the project folder so that our program can able to detect.

If we didnt placed the input file in the project folder we will get FileNotFoundException.

Could you plz go through this code and let me know if u need any changes in this.Thank You
