Java Character Pattern Program

In this tutorial, we will go through alphabet pattern programs in java programming. Before that, you may go through the following topic in java.

Java Character Pattern Program

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
