ITEC 120 LAB 17

Fun with arrays

Write a program which will read in some number of characters. You will use a char array. (You only need one java file with a main method for this project.) Your program will:

read in an integer which will tell you how many characters you will be given to read in
read in that many characters, one character at a time (from the keyboard. Redirect from a file if you wish.)
store the characters in an array
count the number of uppercase characters in the array
count the number of lowercase characters in the array
count the number of non-alphabetic characters in the array
output the total uppercase chars, lowercase chars, and non-alpha chars you found
output the array of characters forward
output the array of characters backwards

Sample run:

Program outputs:	How many characters do you want to type in?
User inputs:	8
Program outputs:	Enter character 1:
User inputs:	a
Program outputs:	Enter character 2:
User inputs:	b
Program outputs:	Enter character 3:
User inputs:	c
Program outputs:	Enter character 4:
User inputs:	5
Program outputs:	Enter character 5:
User inputs:	!
Program outputs:	Enter character 6:
User inputs:	X
Program outputs:	Enter character 7:
User inputs:	Y
Program outputs:	Enter character 8:
User inputs:	Z
Program outputs:	There were 3 uppercase letters. There were 3 lowercase letters. There were 2 characters that were not letters. abc5!XYZ ZYX!5cba

Once you have your program working, show your lab to the Peer Instructor to be checked off. Run the program with lab17in.txt as input.
