[教材P105 3-36、3-37（给出java代码和运行效果示意图）] 实现颜色类和像素类，要求像素类重写toString方法，以 [x,y,(r,g,b)]格式返回像素对象的信息

颜色类：

public class Color {
    private int red;
    private int green;
    private int blue;

    public Color(int red, int green, int blue) {
        this.red = red;
        this.green = green;
        this.blue = blue;
    }

    public int getRed() {
        return red;
    }

    public int getGreen() {
        return green;
    }

    public int getBlue() {
        return blue;
    }
}

像素类：

public class Pixel {
    private int x;
    private int y;
    private Color color;

    public Pixel(int x, int y, Color color) {
        this.x = x;
        this.y = y;
        this.color = color;
    }

    public int getX() {
        return x;
    }

    public int getY() {
        return y;
    }

    public Color getColor() {
        return color;
    }

    @Override
    public String toString() {
        return "[" + x + "," + y + "," + "(" + color.getRed() + "," + color.getGreen() + "," + color.getBlue() + ")]";
    }
}

测试代码：

public class TestPixel {
    public static void main(String[] args) {
        Color color = new Color(255, 0, 0);
        Pixel pixel = new Pixel(10, 20, color);
        System.out.println(pixel.toString());
    }
}

输出结果：

[10,20,(255,0,0)]
