java爱心动态代码

以下是Java实现爱心动态代码的例子：

public class Heart {
    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) {
            for (double j = 0; j < 2 * Math.PI; j += 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);
                size = Math.sin(j);
                int x1 = (int) (x * size + 30);
                int y1 = (int) (y * size + 15);
                heart[y1][x1] = '*';
            }
        }
        for (int i = 0; i < 30; i++) {
            for (int j = 0; j < 60; j++) {
                System.out.print(heart[i][j]);
            }
            System.out.println();
        }
    }
}
