打印字母倒心图案的Java程序

字母倒心图案由两部分组成。图案的上部是一个三角形。图案的底部有两个峰和它们之间的间隙。因此，所需的图案如图所示。

方法：

打印相同的方法非常简单，首先我们将关注上半部分去除下半部分。所以我们只需要打印上金字塔图案，我们需要维护和更新递增字母的额外计数。以字符类型的首字母开始隐式转换为整数类型，增量与相应的 ASCII 值一起传递给字符。同样，对于下半部分，在主要关注打印空白的基础之后

例子

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++) {
                System.out.print(" ");
            }
  
            // Iterating using for loop to print characters
            for (int j = 0; j < n; j++) {
                System.out.print(a);
            }
  
            // Iterating using for loop to print spaces
            for (int j = 0; j < spaces; j++) {
                System.out.print(" ");
            }
  
            // By now over with one row so switching to next
            // row
            System.out.println();
  
            n = n + 2;
  
            // Incrementing the alphabet characters
            // Initially at 'a' now getting to 'b'
            a++;
        }
  
        // Declaring and initializing variable representing
        // number of spaces to be printed in base part
        int spaces_end = 0;
  
        // Declaring and initializing variable representing
        // number of spaces to be printed between two part
        // of base
        int spaces_between = 0;
  
        // For loop to print base part
        for (int i = 0; i < base_size; i++) {
            n = (size - (2 * (spaces_end)) - spaces_between)
                / 2;
  
            // For loop to print space before base part-1
            for (int j = 0; j < spaces_end; j++) {
                System.out.print(" ");
            }
  
            // For loop to print base part-1
            for (int j = 0; j < n; j++) {
                System.out.print(a);
            }
  
            // 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;
        }
    }
}
