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
{
    priva         


        

Answer 1

This should be by far the shortest and simplest way:

        _radius = Math.hypot(x, y);
        _alpha = Math.toDegrees(Math.atan2(y, x));

Keep in mind that when computed this way, _alpha will have values between -180 and 180 degrees.
