[Java][Exerise] Palindrome

Anonymous A palindrome is a word that reads the same backward or forward.

Write a function that checks if a given word is a palindrome. Character case should be ignored.

For example, isPalindrome("Deleveled") should return true as character case should be ignored, resulting in "deleveled", which is a palindrome since it reads the same backward and forward.

public class Palindrome {
    public static boolean isPalindrome(String word) {
        word = word.toLowerCase();
        int len = (int) Math.floor(word.length()/2);
        for(int i=0;i<len;i++){
            if(word.charAt(i)!=word.charAt(word.length()-i-1)){
                return false;
            }
        }
        return true;
    }
   
    public static void main(String[] args) {
        System.out.println(Palindrome.isPalindrome("Deleveled"));
    }
