Question

The following UML diagram is for a class that represents the cost of a job done at a certain car repair shop: ServiceQuote -partsCharge: double -laborCharge: double +ServiceQuote() +ServiceQuote(parts: double, labor: double) +setPartsCharge(c: double): void +setLaborCharge(c: double): void +getPartsCharge(): double +getLaborCharge().- double +calcSales Tax(): double +calcTotalCharge(): double Part 1 Write a class ServiceQuote that follows this UML diagram. Assume the sales tax rate is 6% and is only calculated on the parts not the labor. The total charge is the total of parts, labor and tax. Part 2 Write a class Tests that will do the following in a main (use System.out for all displaying): inimi two Instantiate an object of class Service Quote using the empty constructor. Set the parts charge of this object to $324.56. Set the labor charge of this object to $275. Calculate and display the sales tax. Calculate and display the total charge. Instantiate an object of class ServiceQuote using $783.56 for parts cost and $250 for labor costs. Display the parts charge, labor charge, tax and total charge for this object.

Sorry for the long and strange question, but this is supposed to be written in java;

Answer 1

CODE IN JAVA:

ServiceQuote.java file:

public class ServiceQuote {
   private double partsCharge;
   private double laborCharge;

   public ServiceQuote() {
   }

   public ServiceQuote(double partsCharge, double laborCharge) {
       this.partsCharge = partsCharge;
       this.laborCharge = laborCharge;
   }

   public double getPartsCharge() {
       return partsCharge;
   }

   public void setPartsCharge(double partsCharge) {
       this.partsCharge = partsCharge;
   }

   public double getLaborCharge() {
       return laborCharge;
   }

   public void setLaborCharge(double laborCharge) {
       this.laborCharge = laborCharge;
   }

   public double calcSalesTax() {
       return this.partsCharge * 0.06;
   }

   public double calcTotalCharge() {
       return this.partsCharge + this.laborCharge + this.calcSalesTax();
   }
}

TestSQ.java file:

public class TestSQ {

   public static void main(String[] args) {
       ServiceQuote sq = new ServiceQuote();
       sq.setPartsCharge(324.56);
       sq.setLaborCharge(275);
       System.out.printf("Sales Tax : $%.2f\n", sq.calcSalesTax());
       System.out.printf("Total charge : $%.2f\n", sq.calcTotalCharge());

       ServiceQuote sq2 = new ServiceQuote(783.56, 250);
       System.out.printf("Parts LCharge : $%.2f\n", sq2.getPartsCharge());
       System.out.printf("Labor Charge : $%.2f\n", sq2.getLaborCharge());
       System.out.printf("Sales Tax : $%.2f\n", sq2.calcSalesTax());
       System.out.printf("Total charge : $%.2f\n", sq2.calcTotalCharge());

   }

}
