Check palindrome using recursion in java

Problem:

Write a recursion boolean method that checks if a string is a palindrome.

Output:

Not applicable.

Solution:

public static boolean isPalindrome(String s) {
if (s.length() <= 1) // Base case
return true;
 else if (s.charAt(0) != s.charAt(s.length() - 1)) // Base case
 return false;
 else
 return isPalindrome(s.substring(1, s.length() - 1));
  }
