Plugin Help Help with checking variables

I am relatively new to bukkit and I was trying to make dodge feature however there is one problem, I don't know how to check for the 'dir' variable that shows the player's direction. And then teleport them accordingly. Am I missing something obvious?

1. @EventHandler
2. public void onPlayerDamage1(EntityDamageByEntityEvent event) {
4. if (event.getEntity() instanceof Player) {
6. Player player = (Player) event.getEntity();
7. String dir = getPlayerDirection(event);
8. Location playerLoc = player.getLocation();
10. //Here I don't know how to test for 'dir'
11. player.teleport(playerLoc.add(-5, 0, 0));
13. }
15. }
17. String getPlayerDirection (EntityDamageByEntityEvent event) {
19. Player player = (Player) event.getEntity();
21. String dir = "west";
22. float y = player.getLocation().getYaw();
23. int i = (int)((y+8) / 22.5);
25. if (i == 0) {dir = "west";}
26. else if(i == 1){dir = "west northwest";}
27. else if(i == 2){dir = "northwest";}
28. else if(i == 3){dir = "north northwest";}
29. else if(i == 4){dir = "north";}
30. else if(i == 5){dir = "north northeast";}
31. else if(i == 6){dir = "northeast";}
32. else if(i == 7){dir = "east northeast";}
33. else if(i == 8){dir = "east";}
34. else if(i == 9){dir = "east southeast";}
35. else if(i == 10){dir = "southeast";}
36. else if(i == 11){dir = "south southeast";}
37. else if(i == 12){dir = "south";}
38. else if(i == 13){dir = "south southwest";}
39. else if(i == 14){dir = "southwest";}
40. else if(i == 15){dir = "west southwest";}
41. else {dir = "west";}
43. return dir;
45. }

 

@iseemtobelost
try Player.getLocation().getDirection()
EDIT: Read wrong.
Something like this?

Code:

public static String getCardinalDirection(Player player) {
        double rotation = (player.getLocation().getYaw() - 90) % 360;
        if (rotation < 0) {
            rotation += 360.0;
        }
         if (0 <= rotation && rotation < 22.5) {
            return "N";
        } else if (22.5 <= rotation && rotation < 67.5) {
            return "NE";
        } else if (67.5 <= rotation && rotation < 112.5) {
            return "E";
        } else if (112.5 <= rotation && rotation < 157.5) {
            return "SE";
        } else if (157.5 <= rotation && rotation < 202.5) {
            return "S";
        } else if (202.5 <= rotation && rotation < 247.5) {
            return "SW";
        } else if (247.5 <= rotation && rotation < 292.5) {
            return "W";
        } else if (292.5 <= rotation && rotation < 337.5) {
            return "NW";
        } else if (337.5 <= rotation && rotation < 360.0) {
            return "N";
        } else {
            return null;
        }

 

Well the problem wasn't I need a detection system, I have one, but rather I need a way for the plugin to teleport me accordingly. See line 10.
