Java program to display triangle alphabet pattern

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

Pattern programs

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));


}
System.out.println();

}

}

}

When the above code is compiled and executed, it produces the following results

Enter the number of rows: 6
A
BB
CCC
DDDD
EEEEE
FFFFFF
