public class Sheldon {
public static void main(String[] args) {
     
           reverseDisplay("123456");
}
    public static void reverseDisplay(String value){
        reverseDisplay(value, value.length() -1);
        }
    public static void reverseDisplay(String value, int high){
        if (high < 0){
            System.out.print(value.charAt(value.length()-1));
            reverseDisplay(value.substring(0, value.length()-1));
    }
    }

}

Open in new window


This builds with no problem but there is no output. I would expect to see 654321 on the console.
