Java Atan2() Method

Description

The method adapts rectangular directs (x, y) to polar manage (r, theta) and returns theta. atan2() is an inbuilt process in Java that is utilized to return the theta constituent from the polar coordinate.

Syntax

double atan2(double y, double x)

Parameters

Here is the detail of parameters −

• X − X co-ordinate in double data type.
• Y − Y co-ordinate in double data type.

Return Value

• This method returns theta from polar coordinate (r, theta).

Example

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 will produce the following result:
