How do I display the a string a random amount of time and print it out?

Question

I am writing the Nim game program and my teacher wants me to be able to display "Pile 1: @@@@" and other piles as well. The thing is that, the "@" symbol needs to be produced a random amount of times. I have no clue how to do this. Printing strings I'm fine at. I figure if I make the @ a String and print that a random amount times I can do that, its just the random part that's screwing me up.

To get a random integer between MIN and MAX, inclusive, use the following Java code:

 

int n = MIN + (int)Math.floor(Math.random() * (MAX - MIN + 1));

 

Now, you want to print the @ that many (n) times. Just use a simple for loop:

 

for (int i = 0; i < n; ++i)

System.out.print('@'); // indent this, WyzAnt destroys indenting!

 

After the for loop, use System.out.println(); to put the cursor on the next line.
