Java跳动爱心代码，百分百还原跳动的爱心！

以下是Java实现跳动爱心代码的例子：

import java.util.Scanner;

public class Heart {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.print("请输入你想要的爱心大小(1-10)：");
        int size = sc.nextInt();
        sc.close();
        if (size < 1 || size > 10) {
            System.out.println("请输入1-10之间的数字！");
            return;
        }
        String[][] heart = new String[6 * size][6 * size];
        for (int i = 0; i < heart.length; i++) {
            for (int j = 0; j < heart[i].length; j++) {
                double distance1 = Math.sqrt(Math.pow(i - heart.length / 2, 2) + Math.pow(j - heart[i].length / 2, 2));
                double distance2 = Math.sqrt(Math.pow(i - heart.length / 2, 2) + Math.pow(j - heart[i].length / 2 - 1.5 * size * size, 2));
                if (distance1 < 1.5 * size * size || distance2 < 1.5 * size * size) {
                    heart[i][j] = "❤️";
                } else {
                    heart[i][j] = "  ";
                }
            }
        }
        for (String[] row : heart) {
            for (String col : row) {
                System.out.print(col);
            }
            System.out.println();
        }
    }
}
