Program to Print Heart Character Pattern

In the previous article, we have discussed Java Program to Print Ladder Character Pattern

In this article we are going to see how to print the Heart character pattern.

Output :

When no of rows 8   

    ABCD          ABCD
  ABCDEF      ABCDEF
ABCDEFGHABCDEFGH
  ABCDEFGHIJKLMNO
    ABCDEFGHIJKLM
      ABCDEFGHIJK
       ABCDEFGHI
        ABCDEFG
          ABCDE
            ABC
              A

Provided list of Simple Java Programs is specially designed for freshers and beginners to get familiarize with the concepts of Java programming language and become pro in coding.

Approach:

  • Enter total row and store it in an integer variable say row.
  • Take a inner loop to print the column values.
  • Take a nested for loop to print left semi-circle at the beginning.
  • Take a nested for loop to print right semi-circle beginning.
  • Take another nested loop to print a inverted pyramid below the semi-circles.

Java Code to Print Heart Character Pattern

import java.util.Scanner;
public class Main
{
    public static void main(String[] args) 
    {
        //variables declared to iterate rows and columns
        // variable 'row' represents number of rows.
        int r,c, row;
        //Starting ASCII Value
        int ascii=64;
        //Scanner class object created
        Scanner sc= new Scanner(System.in); 
        System.out.print("Enter no of rows = ");
        row=sc.nextInt();
        // loop to print 2 semicircles at the top
        for(r = row/2; r <= row; r+=2)
        { 
            // print spaces
            for(c = 1; c < row-r; c+=2) 
            {  
                System.out.print(" ");  
            }
            // loop to print left semi-circle
            for(c = 1; c <= r; c++)
            {  
                System.out.print((char)(c+ascii));  
            }  
            // print spaces
            for(c = 1; c <= row-r; c++)
            {  
                System.out.print(" ");  
            }  
            // loop to print right semi-circle
            for(c = 1; c <= r; c++)
            {  
                System.out.print((char)(c+ascii));  
            }  
            // move to next line/row
            System.out.println("");  
        }  
         
        // loop to print the inverted pyramid
        for(r = row; r >= 1; r--)
        {
            // adds spaces in each row
            for(c = r; c < row; c++)
            {  
                System.out.print(" ");  
            } 
            // keep on printing star from c=1 till (r*2)-1
            for(c = 1; c <= (r*2)-1; c++)
            {  
                System.out.print((char)(c+ascii));  
            }  
            // move to next line/row
            System.out.println("");  
        }  
  
    } 
}

Output:

Enter no of rows : 8
    ABCD          ABCD
  ABCDEF      ABCDEF
ABCDEFGHABCDEFGH
  ABCDEFGHIJKLMNO
    ABCDEFGHIJKLM
      ABCDEFGHIJK

          ABCDEFG
            ABCDE
              ABC
