linked list  data

-----------------------------------

Objectives:
(1) demonstrate the ability to write, compile, and run a simple Java program.
(2) solve a simple problem using recursion.
(3) demonstrate the ability to use recursion.
(4) demonstrate the ability to diagram a Java program.
Instructions:
A. Set up the compiler on your workstation.
B. Write, compile, and run a Java program that:
(1) prompts the user to type a 5 characters such as a 5 digit number,
(2) calls a parameterless. void, recursive function named "reverse" to print the
number backwards.
C. Diagram (i.e. illustrate with a picture) your program completely.
D. e-mail your source code to me.

need help coming up with  an algorithm for this project

Also, out of curiosity what does the title have to do with the question?

I would guess that has to do with someone's idea of storing a string as a linked list of characters  :lol:

Re: linked list  data

-----------------------------------

here what came up when i try storing strings of characters in linked lists 

import java.util.Scanner;
public class Reversetest 
{
public static String inputstr;
public static int n = 5;
   
    public static void main(String[] args)
    {
        Scanner keyboard = new Scanner(System.in);
        inputstr = keyboard.nextLine();        
      reverse();
    }
    public static void reverse()
    {
        
        if (n >= 0)
        {
        System.out.println(inputstr.charAt(n-1));
        n--;    
        reverse();
        }
         else
        {
            System.exit(0);
        }
            
    }
}

[code]
System.out.println(inputstr.charAt(n-1)); 
[/code]
Since you are indexing into the string anyway, this is effectively a for-loop. Figuring out how to use e.g.
[code]
System.out.println(inputstr.charAt(0));
[/code]
should give you a better feel for recursion.
