How can I define this code so that it can return true when it comes to Palindrome? [duplicate]

Answer 1

I think what you're trying to do is this?

public boolean isPalindrome(String s) {
    for (int i = 0; i < s.length() / 2; i++) {
        if (s.charAt(i) != s.charAt(s.length() - i - 1)) {
            return false;
        }
    }
    return true;
}

You can reverse strings using StringBuilder, so this could be more easy written as

public boolean isPalindrome(String s) {
    return new StringBuilder(s).reverse().toString().equals(s);
}
