Class Palindrome

java.lang.Object

Palindrome

public class Palindrome
extends java.lang.Object

The Palindrome Java application illustrates the use of a stack and a queue in the same program to determine whether a line is a palindrome. The program ignores everything except alphabetic letters, and it ignores the difference between upper- and lowercase letters.

public static boolean is_palindrome(java.lang.String input)

Determine whether a string is a palindrom. Note: All non-letters are ignored, and the case of the letters is also ignored.
