Java Question

Answer

Just use a rotation matrix (taken from https://en.wikipedia.org/wiki/Rotation_matrix):

```
float newX = x*Math.cos(angleRad) - y*Math.sin(angleRad);
float newY = x*Math.sin(angleRad) - y*Math.cos(angleRad);
```

One thing to mention is that you need to make sure that the angle is in radians, so you may need to perform this conversion:

```
float angleRad = angle*Math.PI/180;
```
