Convert from Radians to Degrees in Java

Question

I'm trying to get the alpha angle in degrees from x,y when user creates an object.

I wrote the following constructor:

public class Point {     private double _radius , _alpha;          public Point ( int x , int y )     {         _radius = Math.sqrt ( Math.pow(x,2) + Math.pow (y,2) ) ;         _alpha = ( ( Math.atan (y/x) ) * 180 ) / Math.PI;     }  } 

1. Am I right that _alpha is now an angle in degrees instead of radians that I got from the atan() method ?

2. Is there a simple way to do so ?

Thanks !

Answer 1

Why not use the built-in method Math.toDegrees(), it comes with the Java SE.
