Object Oriented Java Programming
This week
we are going to write an application program file that we will use to research
how to write arithmetic expressions and Boolean expressions, as well as using
String objects and control statements. We will be taking all of the data from
the keyboard. Note that the application will have two major modules. The
user should be able to re-run the complete application as many times as
they like and re-run any module of the application as many times as they like.
A prompt should be issued for all inputs including the response to continue a
module or the complete application.
All output should contain titles and all double variables should be formatted with a reasonable number of decimal places using the DecimalFormat class.
Write one executable Java
application file that will:
Module 1
The
application should:
Prompt the
user to enter the name of the module.
Prompt the
user to enter the values for the base and altitude of an isosceles triangle.
The module
should accept a decimal entry for altitude and an integer value for the base.
Assume the
user will enter valid values for the altitude and base.
Display the
module name, as well as the base and altitude of the triangle.
Calculate
the area and perimeter of the triangle.
Display the
area and perimeter of the triangle.
Prompt the
user to select an option to continue running this module.
If the user selects “ to continue” then the module should
“run again”,
otherwise it should fall through to
module 2.
Module 2
The
application should then continue to:
Prompt the
user to enter the name of the module.
Prompt the
user to a enter a destination city for an airline ticket.
Prompt the
user to a enter a destination region code (1 digit 0 – 9).
Prompt the
user to a enter an origin city.
Prompt the
user to a enter an origin region code (1 digit 0 - 9)
Prompt the
user to a enter the number of bags to be checked.
Assume the
user will enter valid values for the region codes and number of bags checked.
Calculate
the cost of the ticket. If the difference between the two region codes is
greater than 5
then the ticket price is $189.00 and
the cost per bag is $11.00, otherwise the ticket price
is $99.00 and the cost per bag is
$5.00.
Display the
module name
Display the
destination city and the destination region code.
Display the
origin city and the origin region code.
Display the
number of bags checked.
Display the
ticket price.
Prompt the
user to select an option to continue running this module.
If the user selects “ to continue” then the module should
“run again”,
otherwise it
should fall through to the end of the application.
At the end
of the application the user should be prompted to continue re-running the
application
or return to the
operating system.
Notes:
1. Label the end of all classes, methods, and blocks with a
comment.
2. Line up the beginning brace { and ending brace }
vertically for each block. (i.e. for each class, method, and block)
3. Indent all code between the beginning and ending braces
so that the lineup of braces can be easily observed.
4. Include comments at the
beginning of every .java source file
with the assignment number, author, date due, and an essay (with paragraphs) at
the start of the file describing the functionality of each class as well as how
each class “works”. User instructions should also be provided. Are there comments
reference important or complex syntax?
5. Insert dividers/separators (i.e. a line of dashes or a line of asterisks) between each method and class.
6. Capture your test results and paste them into the end of
your .java source class file as comments.
7. Submit an electronic copy of your .java source class
files (with the test results “pasted in” as comments) for credit. Note that all
submissions should be made as attachments to an email, and sent to the
instructor with the following subject line:
CIS73
Lab x
where x = the lab
assignment number. Note that the subject line is case sensitive.
8. Note that assignments should be submitted on or before the
due date for
full credit
per the course policies.
9. Note once again that all duplicate .java files that are
submitted for a grade will NOT be graded.
10. There is no substitution for adequate
preparation.
