How do i get the angle from a joystick?

I am using LWJGL's controller class to connect my controller and play around. I wanted to make a game where the player will face the direction the joystick is pointed and they press 'A' to fire. To rotate the player sprite i need to know the angle. I know how to get the input and the joystick inputs are in two floats, X and Y locations from -1.0 to 1.0. How would i be able to use these two numbers to find the angle that the joystick is pointing?

Use the arc tangent function. Something like Math.Atan2(Y, X), that gives you an angle in radians. Then you multiply by 57.... to get degrees. Don't call it if both X and Y are zero.
