Question

i need to write a method that takes in a string as a parameter and prints the word in mirrored form. for example, “hello” should return “helloolleh”. I have to use recursion and cannot use for loops. Here is my code so far:

public static String printMirrored(String str)
{
    if(str == null || str.equals(""))

    {
        return str;
    }
    else
    {
        return str + printMirrored(str.substring(1)) + str.charAt(0);
    }
}

My output is “helloellollolooolleh” which obviously has some extra things in there. Any pointers would be greatly appreciated!

Answer 1

Try using str.charAt(0) at the beginning instead of str.
