Get the "left/right"-neighbor of a block

Hi guys,

I'm really happy with the API and I want to programm a plugin, where players can build hatches for their castles or their houses.
I don't know, how to find out, what is the left and the right neighbor block of one block.
I know, that in a 3D-world, there is no left and right, there are just the x,y and z coordinate and the orientation.
Anyone an idea, how I can get the block, which is one position to the right of my origin block? The right side means the right side of the players view.

Player.getLocation().getYaw() will give you the rotation of the player on the y axis.
You have four cases 0°-90°, 90°-180°, 180°-270° and 270°-360°/0°
you then have to test if your neighbour-blocks to the origin block are at x-1/x+1, z-1/z+1, x+1/x-1 and z+1/z-1 depending on each case.

 

Thanks for the hint, I had a lag on my brain, so simple. Question ist, what the rotations resemple.
0-90°(or is it a half pi ) stands for north and is it going clockwise? I'm missing some comments in the code and some examples for the java doc.

Edit:
90° = NORTH
180° = EAST
270° = SOUTH
360° = WEST

And it is in degree instead of the mostly used radiants
