Question about a combination of keys being pressed

Hi. I'm fairly new to processing and I was wondering how to make a simple circle move diagonally. I can make it move up, down, right, and to the left, but not in a diagonal direction (ie. diagonally down and to the right).

I tried using an if statement and setting it to, for example, if (keyCode == DOWN && keyCode == RIGHT){ cX+=; cY+=2;}, but have had no success.

Can anyone tell me what I'm doing wrong? Thanks!
2. int page = 1;
3. float backgroundFill = 255;
4. int cX = 400;
5. int cY = 400;
7. void setup(){
8. size(800,800);
9. }
11. void draw(){
12. background(backgroundFill);
13. // if (page == 1){
14. // }
15. displayC();
16. moveC();
17. //displayE();
18. //moveE();
19. //areaSize();
20. }
21. void displayC(){
22. ellipse(cX,cY,10,10);
23. }
24. void moveC(){
25. if (key == CODED && keyPressed == true) {
26. if (keyCode == UP) {
27. cY-=2;
28. }
29. }
30. if (key == CODED && keyPressed == true) {
31. if (keyCode == DOWN) {
32. cY+=2;
33. }
34. }
35. if (key == CODED && keyPressed == true) {
36. if (keyCode == RIGHT) {
37. cX+=2;
38. }
39. }
40. if (key == CODED && keyPressed == true) {
41. if (keyCode == LEFT) {
42. cX-=2;
43. }
44. }
45. if (key == CODED && keyPressed == true) {
46. if (keyCode == DOWN && keyCode == RIGHT){
47. cX+=2;
48. cY+=2;
49. }
50. }
51. if (key == CODED && keyPressed == true){
52. if (keyCode == UP && keyCode == RIGHT){
53. cY-=2;
54. cX+=2;
55. }
56. }
57. if (key == CODED && keyPressed == true) {
58. if (keyCode == DOWN && keyCode == LEFT){
59. cX-=2;
60. cY+=2;
61. }
62. }
63. if (key == CODED && keyPressed == true) {
64. if (keyCode == UP && keyCode == LEFT){
65. cX-=2;
66. cY-=2;
67. }
68. }
69. }
