The java.lang.Math.toDegrees() is used to convert an angle measured in radians to an approximately equivalent angle measured in degrees.
Note: The conversion from radians to degrees is generally inexact; users should not expect cos(toRadians(90.0)) to exactly equal 0.0.
Syntax:
public static double toDegrees(double rad) Parameter: rad : This parameter is an angle in radians which we want to convert in degrees. Return : This method returns the measurement of the angle rad in degrees.
Example: To show working of java.lang.Math.toDegrees() method.
// Java program to demonstrate working // of java.lang.Math.toDegrees() method import java.lang.Math;
class Gfg {
// driver code
public static void main(String args[])
{
// value of PI in degrees
double rad = Math.PI;
System.out.println(Math.toDegrees(rad));
// value of PI/2 in degrees
rad = (Math.PI) / 2 ;
System.out.println(Math.toDegrees(rad));
// value of PI/4 in degrees
rad = (Math.PI) / 4 ;
System.out.println(Math.toDegrees(rad));
}

Output:
180.0 90.0 45.0
