Check if a string is palindrome?

Palindrome.java

public class Palindrome {

    public static void main(String[] args) {
        String st = "abcecba";
        System.out.println(isPalindrome(st));
    }
    
    public static boolean isPalindrome(String st) {
        for(int i = 0; i < st.length() - i - 1; i++) {
            if(st.charAt(i) != st.charAt(st.length() - 1 - i)) {
                return false;
            }
        }
        return true;
    }

}
