Program to Display Pascal Triangle in java

 class Main
 
  {

 public static void pascalTriangle(int n)

     { 
      
 
        for (int j = 0; j < n; j++) {
            int num = 1;
            System.out.printf("%" + (n - j) * 2 + "s", "");
            for (int k = 0; k <= j; k++) {
                System.out.printf("%4d", num);
                num = num * (j - k) / (k + 1);
            }
            System.out.println();
        }
    }
  public static void main(String[] args)
 {

int n=6;
pascalTriangle(n);

 }
}
