Java Program to Print Alphabet Inverted Heart Pattern

Alphabet Inverted Heart Pattern consists of two parts. The upper part of the pattern is a triangle. The base of the pattern has two peaks and a gap between them. Hence, the desired pattern looks like as shown in the illustration.

Approach:

The approach to print the same is very simple first we will be focussing on the upper half removing the lower half. So we simply have to print the upper pyramid pattern where we need to maintain and update the additional count for incrementing alphabet letters. Starting with the initial letter being of character type is implicitly converted to an integer type and increment is carried over with the corresponding ASCII value to the character.  Similarly, for the lower half, after the base taking primary concern of printing white spaces 

Example

Java

// Java Program to print Alphabet Inverted Heart Pattern

// Main class
class GFG {

    // Main Method
    public static void main(String[] args)
    {

        // Declaring a variables to initializing with the
        // value to

        // 1. set the size of Inverted Heart
        int size = 39;

        // 2. set the size of upper part of Inverted Heart
        int tri_size = 20;

        // 3. set the size of base part of Inverted Heart
        int base_size = 6;

        // 4. set the character to be printed in first row
        // of pattern
        char a = 'A';

        // Declaring and initializing variable representing
        // number of characters to be printed in a row
        int n = 1;

        // Upper part of the pattern

        for (int i = 0; i < tri_size; i++) {

            // Declaring variable representing white spaces
            // to be printed before and after triangle
            int spaces = (size - n) / 2;

            // Iterating using for loop to print spaces
            for (int j = 0; j < spaces; j++) {

            // row

            // Incrementing the alphabet characters
            // Initially at 'a' now getting to 'b'

        // number of spaces to be printed in base part

        // number of spaces to be printed between two part
        // of base

        for (int i = 0; i < base_size; i++) {

                / 2;

            for (int j = 0; j < spaces_end; j++) {
                System.out.print(" ");

            for (int j = 0; j < n; j++) {

            }

            // For loop to print spaces between two base
            // parts
            for (int j = 0; j < spaces_between; j++) {
                System.out.print(" ");
            }

            // For loop to print base part-2
            for (int j = 0; j < n; j++) {
                System.out.print(a);
            }

            // For loop to print spaces after base part-2
            for (int j = 0; j < spaces_end; j++) {
                System.out.print(" ");
            }

            // Again in lowe half now done with one row
            // so switching to next row
            System.out.println();

            // Similarly incrementing letter and spaces by
            // unity
            a++;
            spaces_end++;
            spaces_between = spaces_between + 2;
        }
    }
}
