Java Programming: Nested Loop

/* This is a simple demonstration of nested for loops.
The program takes an argument N to generate N x N matrix with element * when row i divides
column j or vice versa.

Running:
$ javac myDivisorPattern.java
$ Java my DivisorPattern 2

*/

public static void main (String [] args) {
int N=Integer.parseInt(args[0]);

for (int j=1; j <= N; j++)
if ((i % j == 0) || ( j % i == 0))
System.out.print("* ");
else
System.out.print(" ");

System.out.println(i);
}
}
