Processing: move an image and shooting

Hi, I'm trying to get an image (in the pokemon class) to move left and right with arrow keys, I was wondering if anyone could help me? I also want to make the image shoot at the targets falling(the pokeball class), if anyone can show me how to code it, I would be grateful.

Main class:
1. PFont font;
2. PImage bg;
3. ArrayList pokeball = new ArrayList();
4. boolean createBall = true;
5. boolean shoot = false;
6. int delayBall = 0;
7. int life = 3;
8. int speed=-2;
10. Pokeball poke;
11. Pokemon pika;
12. void setup()
13. {
14. size(500,500);
15. bg = loadImage("bg.jpg");
16. font = loadFont("Aparajita-Bold-48.vlw");
17. frameRate (60);
18. smooth();
19. pika = new Pokemon(450,0);
20. }
21. void draw()
22. {
23. background(bg); //background
24. pika.pika();
25. //text
26. text("Lives remaining:"+life, width-150,height-30);
27. fill(0);
28. if(life<=0){
29. textFont(font, 30);
30. fill(0);
31. text("Gave Over!", width/2-100, height/2);}
33. //Pokeball falling
34. for(int i=0;i<pokeball.size();i++){
35. poke=(Pokeball)pokeball.get(i);
36. poke.changeY(speed);
37. poke.newBall();
38. }
39. if (createBall&&pokeball.size()<7){
40. pokeball.add(new Pokeball(random(0,480),0));
41. createBall = false;
42. delayBall = 0;
43. }
44. delayBall++;
45. if (delayBall >=50){
46. createBall=true;
47. }
48. }
50. Pokeball class:
51. class Pokeball{
52. float x;
53. float y;
54. PImage img;
56. Pokeball(float pokeX, float pokeY){
57. x = pokeX;
58. y = pokeY;
59. img = loadImage("Pokeball2.png");
61. }
62. void newBall(){
63. image (img, x,y);
64. }
65. void changeY(int y) {
66. this.y-=y;
67. if (this.y>500){
68. this.y=0;
69. }
70. }
71. void changeX(int x){
72. this.x+=x;
73. }
74. }
76. Pokemon class:
77. class Pokemon{
78. PImage pika;
79. float x;
80. float y;
82. Pokemon(float pokeX, float pokeY){
83. x = pokeX;
84. y = pokeY;
85. pika = loadImage("pika.gif");
86. }
87. void pika(){
88. image (pika, 250,400);
89. }
90. }

Processing: Making an array of an image fall

Hi, I'm a beginner to Processing.
I'm trying to make a game where an array of pictures (pokeballs) fall randomly from the top of the screen and the user has to shoot at them and every time the user hits one the speed gets increased by 1. However, I'm having difficulty getting the pokeballs to fall so I was wondering is anyone could help me? To be honest, I've looked at loads of examples and I just don't get it as there's different ways and it's confusing me.
1. Main class:
2. PFont font;
3. int life = 3;
4. boolean playerAlive = true;
5. PImage back;
8. void setup(){
9. size(500,500);
10. font = loadFont("CourierNewPS-BoldMT-48.vlw");
11. image = loadImage("Pokeball2.png");
12. frameRate(60);
13. smooth();
14. back= loadImage("bg.jpg");
15. }
17. void draw(){
18. background (back);
19. image.update();
20. //text
21. text("Lives remaining:"+life, width-250,height-30);
22. fill(0);
23. if(life<=0){
24. textFont(font, 20);
25. fill(0);
26. text("Gave Over!", width/2-100, height/2);
27. }
28. }
30. class Pokeball{
31. float x, y, s;
32. float radius = 20;
33. Pokeball (float x, float y, float s){
34. xpos = x;
35. ypos = y;
36. speed = s;
37. }
39. void update(){
40. ypos+=speed;
41. if (ypos>20+20){
42. ypos = 0-20;
43. speed = 2.0;
44. xpos = random(500);
45. if (xpos - 20<=0){
46. xpos = 30.0;
47. }
48. }
49. }
50. }
52. Pokeball class:
54. PImage[] image = new PImage[500];
55. float x = random (500); //x axies location
56. float y = 505;//y axies location
57. float speed = 2.0;
58. class Pokeball{
60. PImage [] image = {getRandomX(), getRandomX, getRandomX, getRandomX, getRandomX};
61. PImage [] image = {0,0,0,0,0};
62. }
