Write the following character triangle pattern in Java


package demo;
import java.util.Scanner;
public class CharacterTriangle
{
 public static void main(String[] args) 
 {
  char r, c, ch, h;
  System.out.println(“Enter seed character : “);
  Scanner sc = new Scanner(System.in);
  ch = sc.next().charAt(0);
  if (ch >= ‘a’ && ch <= ‘z’) {
   ch = (char)(ch – 32);
  }
  h = ch;
  for (r=”A”; r <= ch; r++, h–) 
  {
   for (c=”A”; c <= h; c++) 
   {
    System.out.print(c);
   }
   for (c = (char)(h – 1); c >= ‘A’; c–) {
    System.out.print(c);
   }
   System.out.println();
  }
 }
}


OUTPUT:
run:
