I think I'm close but somethings wrong. Could someone help me out? Here's the code. I'm pretty sure that it's close.
import java.util.*;
public class CheckPalindrome
{
public static void main(
String args[])
{
String input;
System.out.println("Hello and welcome to the palindrome program!");
System.out.println();
System.out.println("Enter quit to end the program.");
do
{
Scanner keyboard=new Scanner(System.in);
System.out.println("Enter a sentence and I will check it:");
phrase=keyboard.next();//recording the string
palindrome(input);//checking
}
while (!input.equals("quit"));
}
String cleanSentence = clean(args[0].toCharArray());
if (isPalindrome(new String(cleanSentence))) {
System.out.println("Is a palindrome");
} else {
System.out.println("Is NOT a palindrome");
//
// returns true if
word is a palindrome
//
private static boolean isPalindrome(String phrase) {
return phrase.equalsIgnoreCase((new StringBuffer(phrase)).reverse().toString().toUpperCase());
}
//
// removes all non letters from the sentence
//
private static String clean(char [] palindrome) {
String sentence = "";
for (int i = 0; i < palindrome.length; i++) {
if (Character.isLetter(palindrome[i])) {
sentence += palindrome[i];
}
}
return sentence;
}
}
Thanks in advance.
) I'll do better next time, promise!
