In this tutorial, we will write a Java program to display alphabet pyramid patterns. Before that, you may go through the following topic in java.
Trianglular alphabet pattern
This is a program the pattern is that the alphabet starts with A and at every increment of the row there is an increment in alphabet such as A, AB, ABC, and so on.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | 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)(j + 64) + " "); System.out.println(); } } } |
1 2 3 4 5 6 7 8 9 | Enter the number of rows: 7 Output: A A B A B C A B C D A B C D E A B C D E F A B C D E F G |
