Java Program to print a pattern like right angle triangle with repeated number

import java.util.Scanner;
public class demo1 
{
  public static void main(String[] args)
             {
   	          int i,j,n;
                System.out.print("Input number of n : ");
            	Scanner input = new Scanner(System.in);
		   n = input.nextInt();
 
                for(i=1;i<=n;i++)
                     {
	                 for(j=1;j<=i;j++)
	                 System.out.print(i);
	                 System.out.println("");
                     }
            }
