Syntax

Math.atan2(double y, double x) has the following syntax.

public static double atan2(double y,  double x)

Example

In the following code shows how to use Math.atan2(double y, double x) method.

// ww  w  .  ja va2  s  .c o m

public class Main {

   public static void main(String[] args) {

      // get a variable x which is equal to PI/2
      double x = Math.PI / 2;

      // get a variable y which is equal to PI/3
      double y = Math.PI / 3;

      // convert x  and y to degrees
      x = Math.toDegrees(x);
      y = Math.toDegrees(y);

      // get the polar coordinates
      System.out.println("Math.atan2(" + x + "," + y + ")=" + Math.atan2(x, y));

   }
}

The code above generates the following result.
