Hi all,

I have a test tomorrow morning and I'm stuck on this one question on my review and here it is:

1. Write a method that takes an integer n, and returns a String. Assume the integer n is an odd integer between 1 and 9. If the returned String is printed, it should display a box like the one below, when n = 9. The integers in the last row will be n.

-----1-----
----333----
---55555---
--7777777--
-999999999-

What I have so far has some problems that I can't figure out how to fix:

import java.util.*;

public class NumberFigure 
{
    public static String dashes(int num)
    {
        String theDashes = "";
        for (int i = 0; i < num; i++)
        {
            theDashes += "-";
        }
        return theDashes;
    }
    
    public static String numbers(int number)
    {
        String theNumbers = "";
        for (int i = 0; i <= number; i++)
        {
            theNumbers += number;
        }
        return theNumbers;
    }
    
    public static void main(String[] args)
    {
        System.out.println("Enter 1, 3, 5, 7, or 9");
        Scanner scan = new Scanner(System.in);
        
        int num = scan.nextInt();
        String display = box (num);
    }
    
    public static String box(int n)
    {
        String theBox = "";
        for (int i = 1; i <= n; i+=2)
        {
            theBox += dashes((11-i) / 2);
            theBox += numbers(i);
            theBox += dashes((11-i) / 2);
        }
        return theBox;
    }
}
