    Default Need help with a recursion..

    Hello fellows.. In the second method "searchArray2" it shows me an error on "return false", which says that it's incompatible types.. I know that it's about mixing string and int, but what if I want my array to be int, how can I return true if the value is found, false otherwise.
    Thank you

    public class RecursiveCalculator
    {
        public int searchArray(int[] array, int value){ 
            if (value != array.length)
                return value;
            else 
                return -1;
        }
     
        public String searchArray2(String[] array, String value){ 
            if (value != array.length)
                return false;
            else 
                return true;
        } 
     
        public String reverseString(String reverse){
            if (reverse.length() == 0) 
                return reverse;
     
            return reverseString(reverse.substring(1)) + reverse.charAt(0);
        }
    }

    The issue is that the return type of the method is String but you are attempting to return a boolean. This is the same thing:
    String result = true; // error incompatible types

    Return a String or change the return type in the method signature.
