Question

For this week's assignment, you will have program class that has two subroutines and a main routine. The program

should be a part of the 'Firstsubroutines' class and you should name your project Firstsubroutines if you are using Netbeans.

Your program must prompt the user to enter a string. The program must then test the string entered by the user to determine whether it is a palindrome. A palindrome is a string that reads the same backwards and forwards, such as "radar", "racecar", and "able was I ere I saw elba". It is customary to ignore spaces, punctuation, and capitalization when looking for palindromes. For example, "A man, a plan, a canal. Panama!" is considered to be a palindrome.

To determine whether a string is a palindrome, you can: convert the string to lower case; remove any non-letter characters from the string; and compare the resulting string with the reverse of the same string. If they are equal, then the original string is considered to be a palindrome.

Here's the code for computing the reverse of str:
