 Pascal's Triangle Program in Java

Program and Video given below :-

import java.io.*;
import java.util.*;
class Pascal
{
    public static void main(String args[])
    {
        Scanner in= new Scanner(System.in);
        int i,j,k,p,n;
        System.out.println("Enter Number of rows");
        n = in.nextInt();
        int m[]= new int[n*10];
        p=n;
        m[0]=1;
        for(i=0;i<n;i++)
        {
            for(k=p;k>=1;k--)// printing whitespaces
            {
                System.out.print(" ");
            }
            for(j=0;j<=i;j++)// printing numbers
            {
                System.out.print(m[j]+" ");
            }
            System.out.println();
            p--;
            for(j=i+1;j>0;j--)// updating values
            {
                m[j]=m[j]+m[j-1];
            }
        }
    }// end of main method
}// end of class
