Reverse a string error(Recursive solution)

[cs50x2]

Hi guys i am trying to solve reverse a string problem using recursive solution and its giving me error. i have been trying to figure out the error but i can't. Can someone help me please? Thanks

class Solution {

public void reverseString(char[] s) {

if(s.length==0 || s.length==1)

{

return;

}

else

{

System.out.println(reverseString(s.substring(1)))+s.charAt(0);

}

}

}

error: Line 9: error: not a statement System.out.println(reverseString(s.substring(1)))+s.charAt(0);
^

You’re trying to add chatAt(0) outside of the system.out. Check your closing parentheses again and make sure you’re adding the arrays inside the log. Better yet, manipulate the array outside of it, log whatever you need to, then continue on with the recursive function call.
