Creating a recursive method for Palindrome

Question

I am trying to create a Palindrome program using recursion within Java but I am stuck, this is what I have so far:

 public static void main (String[] args){
         


        

Answer 1

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