How to write a Java code with heart symbols?

Here is a code written in Java language that exudes love:

public class LoveHeart {
    public static void main(String[] args) {
        int size = 10;
        int h = size / 2;
        int w = size / 2;

        // 打印上半部分爱心
        for (int y = h; y >= -h; y--) {
            for (int x = -w; x <= w; x++) {
                if (isInLoveHeart(x, y, h, w)) {
                    System.out.print("* ");
                } else {
                    System.out.print("  ");
                }
            }
            System.out.println();
        }

        // 打印下半部分爱心
        for (int y = -h; y <= h; y++) {
            for (int x = -w; x <= w; x++) {
                if (isInLoveHeart(x, y, h, w)) {
                    System.out.print("* ");
                } else {
                    System.out.print("  ");
                }
            }
            System.out.println();
        }
    }

    // 判断坐标 (x, y) 是否在爱心图案内部
    private static boolean isInLoveHeart(int x, int y, int h, int w) {
        double value = Math.pow(x * 0.04, 2) + Math.pow(y * 0.1, 2) - 1;
        return value <= 0;
    }
}

This code uses loops and conditional statements to print a heart shape based on the relationship between the coordinates and the heart pattern. In the main method, the size of the heart is first defined, and then the half-width (w) and half-height (h) are calculated. Next, two nested loops are used to traverse each coordinate point of the heart. Within the loop, the isInLoveHeart method is called to determine if the current coordinate point is inside the heart pattern. If so, it prints *, otherwise it prints a space. Finally, the complete heart pattern is printed using nested loops.
