Write a Java Program to Print Pascal Triangle using For Loop

SOURCE CODE ::

import java.io.*;
public class Pascal
{
    public static void main(String[] args) throws IOException
    {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("\nEnter the number of rows : ");
        int r = Integer.parseInt(br.readLine());
        for(int i=0;i<r;i++)
        {
            for(int k=r;k>i;k--)
            {
                System.out.print(" ");
            }
            int number = 1;
            for(int j=0;j<=i;j++)
            {
 
                 System.out.print(number+" ");
                 number = number * (i - j) / (j + 1);
                  
            }
            System.out.println();
        }
 
    }
}

OUTPUT ::

Enter the number of rows : 6
      1 
     1 1 
    1 2 1 
   1 3 3 1 
  1 4 6 4 1 
 1 5 10 10 5 1
