Degree to Radian, and Radian to Degree

ReturnMethodSummary
static doubletoDegrees(double angrad)Converts an angle in radians to an angle measured in degrees.
static doubletoRadians(double angdeg)Converts an angle in degrees to an angle measured in radians.

public class Main {
  public static void main(String[] args) {

    System.out.println(Math.toDegrees(1.2));
    System.out.println(Math.toRadians(-1.2));
  }
}

The output:


68.75493541569878
-0.020943951023931952

public class Main {
  public static void main(String args[]) {
    double theta = 120.0;
    System.out.println(theta + " degrees is " + Math.toRadians(theta) + " radians.");
    theta = 1.312;
    System.out.println(theta + " radians is " + Math.toDegrees(theta) + " degrees.");
  }
}

The output:


120.0 degrees is 2.0943951023931953 radians.
1.312 radians is 75.17206272116401 degrees.
