Question

Q2.Given an array String[] array ={"civic","level","check","oop","boss","madam","sir"}, write down the

program with method which will print only palindromes from the array. You can use

public static Boolean ifPalindrome()

public static void printPalindrome() as reference.

Your Output should look like:

civic

level

madam

(A palindrome is a word, a sequence of characters which reads the same backward as forward, such as

refer)

Answer 1

public class Main {
    public static boolean ifPalindrome(String word) {
        for (int i = 0, j = word.length() - 1; i < word.length() / 2; i++, j--) {
            if (word.charAt(i) != word.charAt(j)) {
                return false;
            }
        }
        return true;
    }

    public static void printPalindrome(String[] array) {
        for (int i = 0; i < array.length; i++) {
            if (ifPalindrome(array[i])) {
                System.out.println(array[i]);
            }
        }
    }

    public static void main(String[] args) {
        String[] array = {"civic", "level", "check", "oop", "boss", "madam", "sir"};
        printPalindrome(array);
    }
}
