Thread: Recursion Help

I'm having problems finishing my java homework - please help
I need to write a method that draws an upside down pattern based on a given string (what the pattern is made of), and an int n (how many lines it has). So far I've managed to get it to work, but only the "right side up." What am I doing wrong?
This is the code I have now:

public static void printPattern(String str, int n) {
        if (n < 1) {
            return;
        }
	System.out.println(str);
        printPattern(str + str, n - 1);
    }

Example: for printPattern("*", 4) I currently get:

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

and I'm supposed to get:

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

Please help. Thanks in advance!

put what you get into a stack and just pop stuff off the stack.
