i can't get this recursion method to work

[joder2006]

i have a program where a user can input a number and that number creates a pattern of asterisks for example if the number is four it looks like this


*
**
*
****
*
**
*

and eight looks like this

*
**
*
****
*
**
*
********
*
**
*
****
*
**
*

the problems is i can't figure out how to get the spacing to work
here is my code


package recursion;

public class recurse
{ private String temp = "";
private int line = 0;


public void tower(int n)
{
if (n == 1)
{



temp += "*";
System.out.println(temp);
temp = ""; }

else
{

tower((n+1)/2);



for (int x = 0; x < n; x++)
{ temp += "*"; }
space = n;
line++;
System.out.println(temp);
temp = "";

tower((n+1)/2);



}

}


}


when i run the program with the number being 8 i get this
*
**
*
****
*
**
*
********
*
**
*
****
*
**
*

I think the answer is simple but i dunno
