Hi guys I have a Timer Program working already but I need to put a stop button into it. I have been trying the last while to no avail. Heres the code. Any help would be greatly appreciated.

Snake Game Help

I am currently looking to program a snake game. At the moment I have a rectangle(which will be the main snake), which I can move from left to right using the arrow keys. I can't find any code which will allow me to use the up and down arrows to move the rectangle. I have included the code which I am using below. Any help will be greatly appreciated. Thanks :)

MAIN SNAKE
2. import processing.core.PApplet;
3. import javax.swing.JOptionPane;
5. public class Snake extends PApplet{
7. Rect1 play1 = new Rect1(150,10,150,10,this);
8. int keyPressed = 0;
9. int sensitivity = 3;
10. int directionY;
11. int directionX;
13. //Instantiate object with input values
16. public void setup(){
17. size(400,400);
18. smooth();
19. }
21. public void keyPressed(){
22. if(key==CODED) {
23. if (keyCode==LEFT){
24. keyPressed = (-1*sensitivity);
25. play1.move(keyPressed);
26. }
27. else if(keyCode==RIGHT){
28. keyPressed = (1*sensitivity);
29. play1.move(keyPressed);
30. }
33. else if (keyCode == UP) {
34. keyPressed();
35. play1.move(keyPressed);
36. println("UP");
37. } else if (keyCode == DOWN) {
38. play1.move(keyPressed);
39. println("DOWN");
40. }
41. }
43. }
48. //Draw and move the object
49. public void draw(){
50. this.frameRate(25);
51. //PApplet.println(ra1,x1);
52. background(150,240,200);
54. play1.display();
56. // Bright red
57. fill(255,200,0);
58. ellipse(20,20,16,16);
61. }
63. }
RECTANGLE
2. import processing.core.PApplet;
4. public class Rect1 {
6. int x1,y1,x2,y2;
8. float speed;
9. PApplet parent;
11. Rect1(int startX, int startY, int endX, int endY, PApplet p){
12. parent = p;
13. x1 = startX;
14. y1 = startY;
15. x2 = endX;
16. y2 = endY;
17. }
19. void display(){
20. parent.fill(255,100,100);
21. parent.noStroke();
22. parent.rect(x1,y1,x2,y2);
24. }
26. void move(int move){
27. x1 +=move;
28. }
29. }
