Changes in the economy have determined that for the EZ shipping company, a surcharge will be assessed on all packages that meet certain criteria. The surcharge is a function of the characteristics of the package and the zip code to which it is sent.
If the first digit of the zip code is a "4" then there is an additional surcharge of 5% on the shipping cost. If the first digit of the zip code is a "6" then there is an additional shipping cost surcharge of 9% based on the weight of the package. For all other zip codes there is an additional shipping cost surcharge of 14%. Additionally,t.
In addition to the surcharges, the regular charges for shipping are calculated as follows: For all weights under five pounds, the charge is $12.00.
For weights over five pounds, the charge is calculated as follows:
If length * width * height + weight is:

  • Between 5.1 and 15, the charge is 14.00
  • Between 15. 1 and 34, the charge is 17.00
  • Between 34. 1 and 45, the charge is 21.00
  • Between 45.1 and 60, the charge is 33.00
  • Greater than 60, the charge is 105.00
Write a program that allows the user to input the zip code and the characteristics of the package then prints out the following:

Bar Chart:
Write a program that asks the user to enter today's sales for five stores. The program should display a bar chart comparing each store's sales. Create each bar in the bar chart by displaying a row of asterisks. Each asterisk should represnet $100 of sales. Do not accept any number less than $100.00. Here is an example of the program's output:
Enter today's sales for store 1: 1000[enter]
Enter today's sales for store 2: 1200[enter]
Enter today's sales for store 3: 1500[enter]
Enter today's sales for store 4: 0800[enter]
Enter today's sales for store 5: 1900[enter]

Rectangle Area

  • getLength — This method should ask the user to enter the rectangle’s length, and then return that value as a double.

  • • getWidth — This method should ask the user to enter the rectangle’s width, and then return that value as a double.

  • • getArea — This method should accept the rectangle’s length and width as argu-ments, and return the rectangle’s area. The area is calculated by multiplying the length by the width.

  • • displayData — This method should accept the rectangle’s length, width, and area as arguments, and display them in an appropriate message on the screen.

Design a Payroll class that has fields for an employee's name, ID number, hourly pay rate, and number of hours worked. Write the appropriate accessor and mutator methods and a constructor that accepts the employee's name and ID number as arguments. The class should also have a methods that returns the employee's gross pay, which is calculated as the number of hours worked multiplied by the hourly pay rate. Write a program that demonstrates the class by creating a Payroll object, then asking the user to enter the data for an employee. The program should display the amount of gross pay earned.
In this exercise, you need only provide the definition of the Payroll class. The demonstration class (PayrollDemo) is provided for you. Accessor and mutator methods for the name, idNumber, hoursWorked, and payRate attributes should follow the standard naming conventions introduced in the chapter (e.g., getIdNumber and setIdNumber). The method that returns the employee's gross pay should be named getGrossPay.




/**
 * Class to represent the payroll for an employee
 *
 * @JaziGarcia

public class Payroll
{
    public String name;
    public String id;
    public double hoursWorked;
    public double payRate;

    /**
     * Constructor for objects of class Payroll
     */
    public Payroll(String newName, String newID) {
        name = newName;
        id = newID;
    }

    public String getName() {
        return name;
    }

    public String getID() {
        return id;
    }
   
    public void setHoursWorked(double hours) {
        hoursWorked = hours;
    }

    public double getHoursWorked() {
        return hoursWorked;
    }
   
    public void setPayRate(double rate) {
        payRate = rate;
    }
   
    public double getPayRate() {
        return payRate;
    }
   
    public double getGrossPay() {
        return hoursWorked*payRate;
