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 class palin
{ 
    static boolean isPalin(String s, int i, int j)
    {
        boolean b=true;
        if(s.charAt(i)==s.charAt(j))
        {
            if(i<=j)
                isPalin(s,(i+1),(j-1));
        }
        else
        {
            b=false;
        }
        return b;
    }
    public static void main()
    {
        String s1="madam";
        if(isPalin(s1, 0, s1.length()-1)==true)
            System.out.println(s1+" is palindrome");
        else
            System.out.println(s1+" is not palindrome");
    }
}
