In this tutorial, we will go through alphabet pattern programs in java programming. Before that, you may go through the following topic in java.

• for loop in java

Java Character Pattern Program

import java.util.Scanner;

public class Main
{
  public static void main(String args[])
  {
    int rows, i, j, k;
    Scanner sc = new Scanner(System.in);

    System.out.print("Enter the no. of rows: ");
    rows = sc.nextInt();

    for (i = 0; i <= rows; i++)
    {
      int alphabet = 65;
      for (j = 0; j < i; j++)
        System.out.print(" ");

      for (k = i; k <= rows; k++)
        System.out.print((char)(alphabet + k)+" ");

      System.out.println();
    }
    for (i = rows; i >= 0; i--)
    {
      int alphabet = 65;
      for (j = 0; j < i; j++)
        System.out.print(" ");

      for (k = i; k <= rows; k++)
        System.out.print((char)(alphabet + k)+" ");

      System.out.println();
    }
  }
}

Output:

Enter the no. of rows: 5
A B C D E F
 B C D E F
  C D E F
   D E F
    E F
     F
     F
    E F
   D E F
  C D E F
 B C D E F
A B C D E F

In this tutorial, we will write a program to display a right-angle triangle pattern in java using the alphabet. Before that, you may go through the following topic in java.

• for loop in java

The program below takes the user input from the user for the number of rows and display the right triangle character pattern in various character orders.

Right angled triangle pattern

import java.util.Scanner;

public class Main
{
  public static void main(String args[])
  {
    int rows, i, j;
    int ch = 64;
    Scanner sc = new Scanner(System.in);

    System.out.print("Enter the number of rows: ");
    rows = sc.nextInt();

    System.out.print("Output:\n");
    for (i = 1; i <= rows; i++)
    {
      for (j = i; j >= 1; j--)
        System.out.print((char)(j + ch)+" ");

      System.out.println();
    }
  }
}

Output:

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

In this tutorial, we will write a java program to display the reverse right triangle pattern using the alphabet. These are character pattern programs in java. Before that, you may go through the following topic in java.

• for loop in java

The program below takes the user input from the user for the number of rows and displays the reverse right triangle character pattern in various character orders.

This program can also be called the inverted half pyramid in java or Floyd’s triangle alphabet pattern in java.

Reverse right angled triangle pattern

In this program, the decrement of the Alphabet starts from the left corner of the pattern.

import java.util.Scanner;

public class Main
{
  public static void main(String args[])
  {
    int rows, i, j;
    int ch = 64;
    Scanner sc = new Scanner(System.in);

    System.out.print("Enter the no. of rows: ");
    rows = sc.nextInt();

    System.out.print("Output:\n");
    for (i = 1; i <= rows; i++)
    {
      for (j = i; j <= rows; j++)
        System.out.print((char)(j + ch));

      System.out.println();
    }
  }
}

Output:

Enter the no. of rows: 5
Output:
