=== Discussion
#skind[Classes, interfaces and methods used from Java standard library]
- The `double Math.abs(double)` method returns the absolute value of the given `double` value.
- `java.util.Scanner` class:
- `double nextDouble()`: Scan a `double` value from the the input stream.
- `java.util.InputMismatchException` is thrown by the methods of `Scanner` class when encountering invalid input.
#skind[Classes and methods implemented in the program]
- The `Complex` class objects represents a a complex number.
- Constructor `Complex(double, double)`: Create a complex number object from the provided real and imaginary parts.
- `public String toString()` method returns the string representation of the complex number.
- The `ComplexOperations` class
- The `CylinderCalculationsCLI` orchestrates a main program with:
- `public static void main(String[])`: Creates a cylinder object with its radius and height given as command-line arguments.
- The `CylinderCalculationsScan` orchestrates a main program with:
- `public static void main(String[])`: Creates a cylinder object with its radius and height taken from user using `java.util.Scanner`.
