Chapter 3, Problem 10PE

Explanation of Solution

Program code:

JobPricing.java

//import the packages

import java.util.Scanner;

//define class JobPricing

class JobPricing

{

//define main() method

public static void main(String[] args)

{

//variable to store name of the job

String description;

//variable to store cost of materials

double materials;

//variable to store working hours

double hoursOnJob;

//variable to store traveling hours

double hoursOnTraveling;

//variable to store total cost for the job

double price;

//create an object of Scanner

Scanner input = new Scanner(System.in);

//prompt for job name

System.out.print("Enter job description >> ");

//reading job name

description = input.nextLine();

//prompt for cost of materials

System.out.print("Enter cost of materials >> ");

//reading cost of materials

materials = input.nextDouble();

//prompt for working hours

System.out.print("Enter hours on the job work >> ");

//reading working hours

hoursOnJob = input.nextDouble();

//prompt for traveling hours

System.out.print("Enter hours traveling >> ");

//reading traveling hours

hoursOnTraveling = input.nextDouble();

//calling method computePrice to calculate total cost

price = computePrice(materials, hoursOnJob, hoursOnTraveling);

//printing output

System.out...
