Help with my nested loop...

Question

this application allows a user to enter two int values, rows(height) and columns(length), that are used to create a box of asterisks.
my createBox() does not work correctly, only prints first line, loops infinitely, or doesnt loop. can someone help me out please?
import java.io.*;
public final class AsteriskBox
/****InstanceVariables****/
public static int row;
public static int col;
/****Constructor()****/
public AsteriskBox()
/****Access()'s****/
public void createBox(int x, int y)
if((x > 0) && (y > 0))
for(int i = x; i > 0; i--)
for(i = y; i > 0; i--)
System.out.print("*");
System.out.println();
} // createBox()
public void getInput() throws IOException
BufferedReader input = new BufferedReader
(new InputStreamReader(System.in));
System.out.print("Enter a number of rows: ");
String inputString = input.readLine();
row = convertStringToInteger(inputString);
System.out.print("Enter a number of columns: ");
inputString = input.readLine();
col = convertStringToInteger(inputString);
} // getInput()
/****Helper()****/
private int convertStringToInteger(String s)
Integer intObject = Integer.valueOf(s);
return intObject.intValue();
} // convertStringToInt()
} // AsteriskBox class
import java.io.*;
public class AsteriskBoxUser
public static void main(String args[]) throws IOException
AsteriskBox box = new AsteriskBox();
System.out.println("This program creates a box made of asterisks with values given by you!");
System.out.println();
box.getInput();
box.createBox(AsteriskBox.row, AsteriskBox.col);
}

You will never break out of the first loop because you are using the same index variable i for both of your nested loops. Use a different variable, say j for your inner loop.
Incidentally, your row and col variables are mislabeled. If you use the static modifier, they are class variables, not instance variables. This could cost you points on your assignment since it would imply that you don't know the difference.
