toDegrees() is a static method that is used to convert a radian angle into approximately equivalent degree measures.
Note:
toDegrees()is an approximate conversion, so it may contain some errors. For example,sin(toRadians(90.0))cannot be exactly equal to 1.0.
static double toDegrees(double radianAngle)
radianAngle: An angle in radian measures.toDegrees() returns the approximate angle value in degrees, which is of type double.
In lines 11 and 13, we use Math.toDegrees() to convert argument values x and y in radian measure. We can also use this method to make our calculations easily, like in trigonometric functions.
