Alphabet Pyramid Pattern in Java

import java.util.Scanner;

public class Main
{
  public static void main(String args[])
  {
    int rows, i, j;
    Scanner scan = new Scanner(System.in);

    System.out.print("Enter the number of rows: ");
    rows = scan.nextInt();

    System.out.print("Output:\n");
    for (i = 1; i <= rows; i++)
    {
      for (j = 1; j <= rows - i; j++)
        System.out.print(" ");

      for (j = 1; j <= i; j++)
        System.out.print((char)(char)(i + 64) + " ");

      System.out.println();
    }
  }
}

Output:

Enter the number of rows: 8
Output:
       A
      B B
     C C C
    D D D D
   E E E E E
  F F F F F F
