java爱心代码编程

以下是 Java 实现爱心图案的代码：

public class Heart {
    public static void main(String[] args) {
        double x, y, size;
        char[][] shape = new char[20][70];

        for (int i = 0; i < shape.length; i++) {
            for (int j = 0; j < shape[i].length; j++) {
                shape[i][j] = ' ';
            }
        }

        for (double theta = 0; theta < Math.PI; theta += 0.01) {
            x = 16 * Math.pow(Math.sin(theta), 3);
            y = 13 * Math.cos(theta) - 5 * Math.cos(2 * theta) - 2 * Math.cos(3 * theta) - Math.cos(4 * theta);
            x += 35;
            y += 10;
            size = Math.sin(5 * theta) * 2 + 8;
            int iX = (int) x;
            int iY = (int) y;
            if (iY >= 0 && iY < shape.length && iX >= 0 && iX < shape[iY].length) {
                shape[iY][iX] = '*';
            }
        }

        for (int i = 0; i < shape.length; i++) {
            for (int j = 0; j < shape[i].length; j++) {
                System.out.print(shape[i][j]);
            }
            System.out.println();
        }
    }
}
