跳动爱心代码java

以下是Java实现跳动爱心的代码：

public class Heart {
    public static void main(String[] args) {
        double x, y, size;
        char[][] s = new char[30][80];
        while (true) {
            for (int i = 0; i < 30; i++) {
                for (int j = 0; j < 80; j++) {
                    s[i][j] = ' ';
                }
            }
            for (double i = 0; i < 2 * Math.PI; i += 0.01) {
                for (double j = 0; j < 2 * Math.PI; j += 0.05) {
                    x = 16 * Math.pow(Math.sin(j), 3);
                    y = 13 * Math.cos(j) - 5 * Math.cos(2 * j) - 2 * Math.cos(3 * j) - Math.cos(4 * j);
                    size = Math.sin(i);
                    int x1 = (int) Math.floor(x * size + 40);
                    int y1 = (int) Math.floor(y * size + 15);
                    if (x1 >= 0 && x1 < 80 && y1 >= 0 && y1 < 30) {
                        s[y1][x1] = '*';
                    }
                }
            }
            for (int i = 0; i < 30; i++) {
                System.out.println(s[i]);
            }
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}
