Hello, I have written these buttons that apply some filters to the image, since I can not have two filters active at a time, is it possible to disable the other when a new one is clicked, I cant figure it out by myself so you need your help.

Thanks in advance.

1. PImage img;
2. Button b1 = new Button(1, "Pixelation");
3. Button b2 = new Button(2, "Noise");
4. 
   
5. void setup() 
6. {
7.   size(500, 340);
8.   textAlign(CENTER, CENTER);
9.   img = loadImage("image.jpg");
10. }
11. 
    
12. void draw() {
13.   background (255);
14.   image(img, 0, 0);
15.   b1.display();
16.   b2.display();
17. } 
18. 
    
19. void mouseClicked() {
20.   b1.overButton();
21.   b2.overButton();
22. }
23. class Button {
24.   boolean selected = false;
25.   int nr, x, y, w, h;
26.   String name;
27. 
    
28.   Button (int inNr, String inName) {
29.     name = inName;
30.     nr = inNr;
31.     w = 70;
32.     h = 20;
33.     x = inNr*(w+10)-w;
34.     y = 340-(h+10);
35.   }
36. 
    
37.   void display() {
38.     if (selected) fill(90);
39.     else fill(150);
40.     rect(x, y, w, h);
41.     fill(0);
42.     text(name, x+(w/2), y+(h/2));
43. 
    
44.     if (nr == 1 && selected) {
45.       pixelation();
46.     }
47.     else if (nr == 2 && selected) {
48.       noize();
49.     }
50.   }
51. 
    
52.   void overButton() {
53.     if (mouseX > x && mouseX < x+w && mouseY > y && mouseY < y+h)
54.       selected = !selected;
55.   }
56. 
    
57.   void pixelation() {
58.     int size = 10;
59.     for (int y = 0; y < img.height; y = y + size) {
60.       for (int x = 0; x < img.width; x = x + size) {
61.         fill(img.get(x, y));
62.         stroke(img.get(x, y));
63.         rect(x, y, size, size);
64.       }
65.     }
66.   }
67.   
68.   void noize() {
69.     for (int y = 0; y < img.height; y = y + 1) {
70.       for (int x = 0; x < img.width; x = x + 1) {
71.         int nX = x + int(random(10));
72.         color getColor = img.get(nX, y);
73.         set(x, y, getColor);
74.       }
75.     }
76.   }
77. }

Hello I am trying to create this class, that creates a button and when clicked changes the color of it. But the way I am doing it is not working, can you tell me what is wrong og tell me another way to achieve the same?

Hello I have written this button, and I was wondering if there is some way to use the "i" at the place of "buttonX" in the rect.

And I would like your input on the code if there is some way I can better it.

Thanks in advance.

1. void setup () {
2.   size (500, 350);
3. }
4. 
   
5. void button (int nr, String text) {
6.   int buttonX = 0;
7.   int buttonY = 100;
8.   int buttonW = 70;
9.   int buttonH = 20;
10. 
    
11.   for (int i = 10; i <= 80*nr; i += buttonW+10) {
12.     buttonX = i;
13.   }
14.   rect (buttonX, buttonY, buttonW, buttonH);
15.   text (text, buttonX, buttonY);
16. }
17. void draw () {
18.   button(1, "Button1");
19.   button(2, "Button2");
20.   button(3, "Button3");
21.   button(4, "Button4");
22.   button(5, "Button5");
23.   button(6, "Button6");
24. }
