Java 程序打印字母倒心形图案
字母倒心形图案由两部分组成。图案的上半部分是三角形。图案的底部有两个峰和一个间隙。因此，所需的模式如图所示。

进场:
打印相同的方法非常简单，首先我们将关注上半部分，去掉下半部分。所以我们只需要打印上面的金字塔模式，在那里我们需要维护和更新增加字母的额外计数。从字符类型的首字母开始，隐式转换为整数类型，并使用相应的 ASCII 值将增量传递给字符。类似地，对于下半部分，在基本考虑打印空白之后
例
Java 语言(一种计算机语言，尤用于创建网站)
// 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;
}
}
}
