  • Similar Alphabet Pyramid Pattern in Java

    Similar Alphabet Pyramid Pattern in Java

    In this tutorial, we will write an alphabet triangular pattern in java where the characters or letters are every row have the same alphabet. Before that, you may go through the following topic in java.

    Example:

    Rows Input: 5
Output:
       A
      B B
     C C C
    D D D D
   E E E E E

    Alphabet Pyramid Pattern 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();

    System.out.print("Output:\n");
    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)(char)(i + 64) + " ");

      System.out.println();
    }
  }
}

  • Java Program to print Half Pyramid using Alphabets in Increasing order

    Java Program to print Half Pyramid using Alphabets in Increasing order

    In this tutorial, we will write a program to display half alphabet pyramid patterns in java. Before that, you may go through the following topic in java.

    Example:

    Rows Input: 5
Output:
A

    This program is also known as right-angled triangle patterns using the alphabet in java as the right angle is formed on the right side of the pattern.

    Java Program to print Half Pyramid using Alphabets

    The program takes a user input for the number of rows to be displayed on the screen. The Alphabet starts from A and increases at every row such as A, Ab, ABC, and so on.

    import java.util.Scanner;

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

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

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

      System.out.print("\n");
    }
  }
}
