Reverse Pyramid with Alphabet in Java

In this tutorial, we will write a reverse alphabet triangle pattern in java. Before that, you may go through the following topic in java.

for loop in java

The program takes a user input for the number of rows to be printed. Then the inverted alphabet pattern is displayed on the screen.

Java Program to display the Reverse Pyramid pattern with Alphabet

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 = rows; i >= 1; i--)
    {
      for (j = 1; j <= rows - i; j++)
        System.out.print("  ");

      for (j = 1; j <= 2 *i - 1; j++)
      {
        if (j <= i)
          System.out.print((char)(char)(j + 64) + " ");
        else
          System.out.print((char)(char)(2 *i - j + 64) + " ");
      }
      System.out.println();
    }
  }
}

Enter the number of rows: 5
Output:
A B C D E D C B A
  A B C D C B A
    A B C B A
      A B A
        A

Alphabet Pyramid Pattern in Java: pattern 1

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.

for loop in java

We will look at pyramid patterns in java using alphabets/letters/characters.

Pyramid triangle alphabet

This is a mirror image pattern of letters in java.

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();

    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)(j + 64));

      for (j = i - 1; j >= 1; j--)
        System.out.print((char)(j + 64));

      System.out.println();
    }
  }
}

Enter the number of rows: 6
     A
    ABA
   ABCBA
  ABCDCBA
 ABCDEDCBA
