Computer Science 2

String class mini-lab:

1)  Write a program that prompts the user to enter a sentence.  The program then does EACH of the following:

a)  Outputs a new sentence that replaces all 'a' characters with 'z' characters.

b)  Outputs a new String that only shows the first 7 characters of the original sentence (so, make sure when you prompt the user for a sentence, that they enter in at least 7 characters, otherwise the method you use to make this work will produce an error).

c)  Outputs a new String that is the same as the original, but all UPPERCASE.

2)  Modify your "Mad Libs" program to do the same three tasks as above.

This is due Friday, February 20th, at 2:30pm.
