The method Converts rectangular coordinates (x, y) to polar coordinate (r, theta) and returns theta.
double atan2(double y, double x)
Here is the detail of parameters:
X and Y co-ordinates in double data types
Returns theta from polar coordinate (r, theta)
public class Test{ public static void main(String args[]){ double x = 45.0; double y = 30.0; System.out.println( Math.atan2(x, y) ); } }
This produces following result:
0.982793723247329
