请用java打印出一个填充过的心形图案

以下是Java代码，可以打印出一个填充过的心形图案：

public class Heart {
    public static void main(String[] args) {
        int size = 10;
        for (int i = size / 2; i <= size; i += 2) {
            for (int j = 1; j < size - i; j += 2) {
                System.out.print(" ");
            }
            for (int j = 1; j <= i; j++) {
                System.out.print("*");
            }
            for (int j = 1; j <= size - i; j++) {
                System.out.print(" ");
            }
            for (int j = 1; j <= i; j++) {
                System.out.print("*");
            }
            System.out.println();
        }
        for (int i = size; i >= 1; i--) {
            for (int j = i; j < size; j++) {
                System.out.print(" ");
            }
            for (int j = 1; j <= (i * 2) - 1; j++) {
                System.out.print("*");
            }
            System.out.println();
        }
    }
}

输出结果：
