The document describes a Java program that implements three user-selectable features: printing the ASCII table, simulating coin flips, and counting vowels and letters in a string. It outlines the use of loops, conditions, and methods to structure the code into logical sections, along with guidance for refactoring portions of the code into methods for assignment purposes. Additionally, it includes instructions for modifications and enhancements that need to be made after the initial implementation.

Assignment #5, 3 features in 1 program
Solution
for Assignment#5 COP2800
Pseudocode:

2. Program has three features, all in a single program that are user
selectable.
Prompt with options and get user choice inside a while
statement ( true )
If 1 is entered:
Using a while and for loop, print out the ASCII table from ! to
~.
If 2 is entered:
Prompt the user for number of times to flip for head or tails
using the random method. Count number of each and when the
request times are done, print out the results.
If 3 is entered:
Prompt the user for a strings and print back the count of vowels
and letters

3. Any other input entered program will exit using a break
statement, otherwise loops back to prompt user for feature
selection.

Assignments:
1. Take the Module 6 Quiz, I recommend you do this AFTER
you complete the
programming assignment!
2. Submit via the module 6 Assignment link your source code
solution (.java file )
to the following:
Program description:
Starting with your Assignment 5 solution, or if you had issues
completing, you
can start with the posted module 5 solution, you are going to
make
modifications to the three features so that they are methods.
The program from the user view is unchanged! This program
will function
exactly as Assignment 5 did, only that instead of features code
in the if/else
block, there will be methods called to run the features, with

16. modifications to
be followed below.
The code for feature 1 is to be moved into a newly created
method called
feature1, feature1 is to be a void method which has no arg value
and does not
return a value. Literally cut and paste the code within the if
block matching to
‘1’ and that code in to be inserted into the new feature1 method,
put the
feature1 method at the end of the file, outside of the main
method block.
The code for feature 2 is to be moved into a newly created
method called
feature2, feature2 is to be a void method ( no return value )
which has one arg
value of type int, called count. The code from the feature 2 that
prompts the
user for the flip value is the passed to the new feature2 method,
the remaining
code is cut and inserted into the new feature2 method put the
feature2
method at the end of the file, outside of the main method block.

17. The code for feature 3 is to be moved into a newly created
method called
feature3, feature3 is to be a String method ( returns a String )
which has one
arg value of type String, called s. The code from the feature 3
that prompts the
user for string message is passed to the new feature3 method,
the remaining
code is cut and inserted into the new feature3 method all but the
print
statements. The print statement(s) are replaced with a return,
and the value
for the return is contents of the original print statements which
is everything
between the parentheses of BOTH print statements.
Note you will have to concatenate ( use + ) and add a n to
match the original
vowel and constant messages.

18. The else if prints out the returned message by calling feature 3
as shown
below:
// call the method of feature 3 providing the message s from the
user, return
// value is the Letters message which is printed to user for the
consonants count
System.out.println(feature3(s));
Put the feature3 method at the end of the file, outside of the
main method
block.
Your program is to look exactly like the output shown below,
only the name
would be different. Notice that an apostrophe is used in the
prompt, your
program must do the same. The example shows all four
possibilities for the
program, option 1,2,3 and any other input by the user which

19. would exit the
program. Highlight in yellow is user provided input.
Tip:
You should do this is steps, start with the easiest, which is
feature 1 change,
when that is completed successfully, the do feature do likewise
feature 2 and
feature 3. Your textbook as has many example that will show
you exactly the
required syntax needed to complete this assignment.
