Java program to display triangle alphabet pattern
In this tutorial, we will discuss a concept of Java program to display triangle alphabet pattern using for loop in java language.
here, we displayed 15 alphabet Floyd’s triangle program with coding and using nested for loop and also we get input from user using Java scanner.
user can provide numbers as they wish and get the alphabet pattern according their input
Java program to display triangle alphabet pattern
Floyd’s Triangle Alphabet Pattern 1
Program 1
import java.util.Scanner;
class AlphabetPatternOne{
public static void main (String args[]){
int i,j;
Scanner scan=new Scanner(System.in);
System.out.print("Enter the number of rows: ");
int rows=scan.nextInt();
for(i=1; i<=rows; i++){
for(j=1; j<=i; j++){
System.out.print((char)(i+64));
