Palindrome Number Java Program

(Palindromes) A palindrome is a string that is spelled the same way forward and backward. Some examples of palindromes are "radar, " "able was i ere i saw elba" and (if blanks are ignored) "a man a plan a canal panama." Write a recursive function testpalindrome that returns true if the string stored in the array is a palindrome, and false otherwise. The function should ignore spaces and punctuation in the string.
