/* Exercvise 6.3 
 * (Palindrome integer) Write the methods with the following headers
 * // Return the reversal of an integer, i.e., reverse(456) returns 654
 * public static int reverse(int number)
 * // Return true if number is a palindrome
 * public static boolean isPalindrome(int number)
 * Use the reverse method to implement isPalindrome . A number is a palin-
 * drome if its reversal is the same as itself. Write a test program that prompts the
 * user to enter an integer and reports whether the integer is a palindrome.
