Question description

Part 1

Write a program to assign the integer values 1 through 25 to a 25-element integer array. Then, print the array as five separate lines, each containing five elements separated by commas. The last element on each line should be followed by a newline instead of a comma. The output of your program should appear exactly as follows:

1,2,3,4,5

6,7,8,9,10

11,12,13,14,15

16,17,18,19,20

21,22,23,24,25

Hints:

One way to determine every 5th element is to use the modules operator (%). If you divide the subscript by 5 and the remainder is 0, it is the 5th number.

You can use System.out.print() to print a value without a newline following it. This allows you to print multiple things on the same line.

You may use the Windows Command Prompt command line interface or any Java IDE you choose to compile and execute your program. You are to submit the following deliverables to the Assignment Dropbox in a single Microsoft Word file:

a. A screen snapshot of your Java source code (just the beginning is OK) as it appears in your IDE (e.g., jGRASP, Net Beans, Eclipse, etc.) or editor (e.g., a Windows Command line more of the .java file's first screen).

b. A listing of your entire Java source code in the same Microsoft Word file as item a), and following item a). You can simply copy and paste the text from your IDE into Microsoft Word. Be sure to maintain proper code alignment by using Courier font for this item.

c. A screen snapshot of your program’s output in the same Microsoft Word file, and following item b).

Inheritance and Polymorphism

PART 2

Key in the PolyMain, Book, Almanac, and Novel classes defined in this module of the course. Once you get each of these classes keyed in, make sure they compile and execute properly. Then create a third subclass called Phone that also extends the Book class. The Phone class should keep track of the number of yellow pages and the number of white pages in each phone book. Make sure the Phone subclass you create has a print method having the same signature as the print method in the Book class. The print method from the Phone class should print the title of the book and the total number of pages of the book, followed by the number of yellow pages and white pages contained within the phone book. Thus, the print method should have the following signature:

public void print();

The Phone class should also have a constructor having the following signature:

public Phone(String title, int whitePages, int yellowPages);

This constructor should sum up whitePages + yellowPages to get the total number of pages in the book. Remember the total pages in the book and the title of the book are set in the constructor for the Book class.

Modify the PolyMain class to create at least one of your phone books and store it in the library. You should now be able to print the library without having to modify the print method defined within the PolyMain class.

You may use any Java IDE you choose to develop your source code, compile and link your code, and execute your program (jGRASP is recommended). Or you may use the Windows Command Prompt.

You are to submit the following deliverables in a single Microsoft Word file in this order, and clearly labeled.

A screen snapshot of your Java source code (all file(s) shown separately) displayed in the IDE or Windows editor showing a successful compilation, if possible (only the beginning of the source file(s) is necessary).

A listing of your entire source code file(s).

A screen snapshot of all of your program's outputs for the specified values in Step #1. Failure to show all of the output will result in lost points. In order to not confuse the grading process, and possibly lose points, do not include any other outputs aside from what is requested.
