Java Fundamentals Homework - Print a Character Triangle


Problem: Print a Character Triangle


Print the characters from ‘a’ to ‘z’ on the console on a single line, separated by a space. Use a for-loop. Note: you can directly declare and increment char in the for-loop. for (char c = ‘a’; …)


import java.util.Scanner;

public class PrintACharachterTriangle {
    public static void main(String[] args) {

        Scanner console = new Scanner(System.in);

        int number = Integer.parseInt(console.nextLine());
        for (int i = 1; i <= number ; i++) {
            for (int j = 0; j<i; j++){
                System.out.print((char) (j + 97) + " ");
            }
            System.out.println();
        }
        for (int i = number - 1; i > 0 ; i--) {
            for (int j = 0; j <i ; j++) {
                System.out.print((char) (j + 97) + " ");
            }
            System.out.println();
        }
    }
}
