Half Repeated Character Pattern in Java

import java.util.Scanner;

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

    System.out.print("Enter the no. of rows: ");
    rows = sc.nextInt();

    for (i = 0; i <= rows; i++)
    {
      int alphabet = 65;
      for (j = 0; j < i; j++)
        System.out.print(" ");

      for (k = i; k <= rows; k++)
        System.out.print((char)(alphabet + k));

      System.out.println();
    }
    for (i = rows; i >= 0; i--)
    {
      int alphabet = 65;
      for (j = 0; j < i; j++)
        System.out.print(" ");

      for (k = i; k <= rows; k++)
        System.out.print((char)(alphabet + k));

      System.out.println();
    }
  }
}

Output:

Enter the no. of rows: 5
