用java写一个爱心跳动代码

以下是Java实现爱心跳动的代码：

public class HeartBeat {
    public static void main(String[] args) {
        double x, y, size;
        char[][] heart = new char[30][60];
        for (int i = 0; i < 30; i++) {
            for (int j = 0; j < 60; j++) {
                heart[i][j] = ' ';
            }
        }
        for (double i = 0; i < 2 * Math.PI; i += 0.01) {
            x = 16 * Math.pow(Math.sin(i), 3);
            y = 13 * Math.cos(i) - 5 * Math.cos(2 * i) - 2 * Math.cos(3 * i) - Math.cos(4 * i);
            x += 30;
            y += 15;
            size = Math.sin(i) * 10 + 10;
            heart[(int) y][(int) x] = '*';
        }
        for (int i = 0; i < 30; i++) {
            for (int j = 0; j < 60; j++) {
                System.out.print(heart[i][j]);
            }
            System.out.println();
        }
    }
}
