THE PROBBLEM: Design and write a program in java that will write out all the printable characters in the ASCII chart with their corresponding ASCII code values. This means the characters numbered 32 through 127, inclusive. The program must have a repeating menu (using a switch statement) with instructions that allow the user to dump out the ASCII chart using a while loop, a do-while loop and a for-loop. Non-printable characters (below 32 or above 127) should be skipped, but the rows should still line up neatly. In each case, the chart should look neat and readable, and each version of the chart should appear to be identical, except for a title at the top identifying which type of loop produced the chart. One option on the menu should allow the user to exit the program.
Example:
ASCII Chart Using While-Loop:
32= 33=! 34=\" 35=# 36=$ 37=% 38=& 39=\'
40=( 41=) 42=* 43=+ 44=, 45=- 46=. 47=/
48=0 49=1 ...
.
.
.
etc. (to char 127)
IMPLEMENTATION: In your program you must write several methods, including ones to write out the menu, to read in an option and (using a switch statement) to call the appropriate function, and three functions to draw the chart each of the three different ways. Note that the idea is to use three different types of loops to produce the charts. Just using System.out and typing it in by hand will not be acceptable. You should also have a working exit option in your menu.
In addition, I want each loop and the menu to exist as separate classes. You will then create objects of those classes in order to access the member methods of each. From here on out, your main method should consist primarily of method calls to other classes, where your actual code will reside.
