Create A Pattern Of Stars

So I'm studying for a test i have coming up on recursion so i was playing around with it. I ended up making a pattern of stars that look that such :

*
**
***

The code i had for that was

public void makePattern(int size){
if(size == 0){
System.out.println();
}
else if(size > 0){
System.out.print("*");
makePattern(size - 1);
}
}

I was wondering if i wanted to expand on this and make it do something like

*
**
***
**
*

What condition would i have to add i was struggling trying to figure it out...
