2. Create a class named Shipment

a. The program must ask for two separate packages to ship

b. The program must calculate the cost difference using the difference in volume: i.e. The base price for a package with volume <=1 is $3, for every unit increase in volume, the cost increases by $1 e.g. 1: a parcel with volume 4, the cost is $3+ $1 +$1 +$1 = $6 e.g. 2: a parcel with volume 2.5, the cost is $3 + $1.5 = $4.5

c. Give the following (in order of priority): i. If there is no difference, display the costs as the same ii. If the cost of one is less than twice the other, display that it is “slightly more than” iii. If the cost of one is less than three times the other, display that it is “twice” iv. If the cost of one is less than four times the other, display that it is “triple” v. If the cost of one is less than five times the other, display that it is “quadruple” vi. Otherwise, display that as a calculated multiple (eg 5x, 6x etc) c. The program must indicate the more costly package (if not same cost) and by how much

d. The program must calculate and display the appropriate message (including proper dimension and cost format) f. Your code also does NOT need to worry if the user inputs an invalid value for the input (example: invalid length). The output of your code must match the samples. g. You must change the title i.e. Welcome to shipping calculator!

The University of Southern North Dakota Testing department needs to write a grading program for multiple choice test. It should be capable of grading tests with up to 50 questions and for any number of students. The program should grade individual exams and calculate the grade for the student based on the number of questions, each being the same value out of 100. For example, if there are 25 questions each is worth 4. This program must be written in Ada.  

The program must also determine how many times each score was earned on the test.  This is a count or frequency. The program must show the number of students graded and the class average.

The program should have 

• an input file. The program asks the user for the name of the file. The file name is entered at the keyboard. All subsequent data is read from the file.
• a score frequency count. Every time a score is computed increment a counter for that value. Any score from 0 to 100 is possible (integer only), so the program needs 101 counters!
• A record type Student_Type containing the student ID and their answers, and t he final grade for the exam.
• A package containing Student_Type as private and operations for reading Student_Type, grading the exam and displaying the student ID and grade.

Behavior not assigned to functions may be done in main.

The program will accept the input file name from the keyboard after prompting the user for the file name.

The first line in the input files contains the number of questions on the exam, the second the answer key, and all following lines contain the student ids and responses to the questions.

21. (2 points) Create a class to represent rectangles. A rectangle is specified (as with drawing them in Processing) by the coordinates of its upper left corner, its width, and its height. Give your class just enough functionality to make it work with the program below. The display() method should simply draw the rectangle with no change in fill or stroke. Rectangle[] boxes = new Rectangle [100]; void setup() { size (400, 400); for (int i = 0; i < boxes.length; i++) { boxes[i] = new Rectangle((int) random (width), (int) random (height), (int) random (10,40), (int) random (5, 20)); void draw() { for (int i = 0; i < boxes.length; i++) { fill (random (255), random (255), random (255)); boxes[i].display();

JAVA Coding Needed

6-Your program MUST be very modular

7-Your output MUST friendly (using labels for all info accordingly) and do display all input and calculated fields.

8-You must implement JOptionPane for all your input and output and must validate all input for all prompts.

Problem’s specifications:

 The GPMS (Green Pollution Monitoring Service ) a fictitious orgaism is tasking you with the coding of an application that monitors the pollution levels of different sites in the USA.

All data are to be stored in an array of 100 object of type ‘Site’

Code a class ‘Site’ with the following attributes and methods:

-the ID of a given site.

-The name of a given site

-the pollution numeric value: adopt data and attributes from the following site

-Index value (see below under option 2 in the menu)

What to do?

-In the main class, declarae an array of 100 object of type ‘Site’

-In the main class, code the following menu in a separate function:

MENU

---------

-1-Add a site

-2-Display a site

-3-Quit

-If user select 1 from the MENU, constract an object site, and call a method in the class ‘Site’ that input data for a given site.

-If user select 2 from the MENU, call a function that search for a site in the array of objects of type ‘Site’  by ID and if found call a function that determines the index value (1 for good, 2 for moderate, 3 for unhealthy for sensitive groups, 4 for unhealthy, 5 for very unhealthy, 6 for hazardous)  based on the pollution numerical value as represented in the given site.

-Call a function member of the class Site, that displays a report about this site (ID, Name, Pollution Value, Index Statement based on the index numerical value)

-Code a function/routine that after the user complete the input of all available sites, displays the site info. that is the most polluted. Also, display how many sites were input for this study.

What to submit?

Submit your complete .Java code named HW3_lastname.java

Extra credits:

-Use ArrayList instead of array of objects
