Question

Java Palindrome

Use StringBuilder concept to create a palindrome checker.  

Method should be called pCheck.

Must use var-arg concept.  

Class name for this program is Palindrome.  

Must pass this test::

public class PalindromeTest {

public static void main(String[] args) {

Palindrome palindrome = new Palindrome();

boolean answer = palindrome.pCheck("racecar", "Bell", "elle", "bunny");

System.out.println(“These are palindromes: " + answer);

}

}

Answer 1

If you have any doubts, please give me comment...

Here I used if all the strings are palindromes, then pCheck method returns true otherwise returns false.

class Palindrome{

    public boolean pCheck(String...strings){

        for(int i=0; i<strings.length; i++){

            int len = strings[i].length();

            for(int j=0; j<len/2; j++){

                if(strings[i].charAt(j)!=strings[i].charAt(len-j-1))

                    return false;

            }

        }

        return true;

    }

}

public class PalindromeTest {

    public static void main(String[] args) {

        Palindrome palindrome = new Palindrome();

        boolean answer = palindrome.pCheck("racecar", "Bell", "elle", "bunny");

        System.out.println("These are palindromes: " + answer);

    }

}

Let me know if any output differ... Thank you...
