Implementation of Diameter, Circumference, and Area Calculation of a Circle in Java

This paper presents a comprehensive Java program that calculates the diameter, circumference, and area of a circle, following the assignment instructions provided by Riverside Community College for the CSC/CIS 18A course. The program demonstrates fundamental Java programming concepts such as input/output, variable declarations, arithmetic operations, and proper class structure. Additionally, it emphasizes good programming practices including commenting, program termination, and packaging code for distribution.

Introduction

Java programming forms the foundational skill for many computer science applications. This assignment emphasizes understanding how to implement basic geometric calculations within Java, reinforcing core programming principles. The specific goals include calculating the diameter, circumference, and area of a circle based on user-input radius, then outputting the results along with timestamps to the console, and finally packaging the program for submission.

Methodology

The Java program begins with importing necessary packages for date and time functionalities. The main class, named CircleCalculations, contains member variables for radius, diameter, circumference, and area, along with methods to calculate each property. To make the program interactive, it prompts the user to input the radius value and then executes calculations based on this input.

Implementation Details

The program first prompts the user for the radius, ensuring user input is read correctly. It then calculates the diameter using the formula diameter = 2 radius. The circumference is computed with 2 Math.PI radius, and the area with Math.PI radius * radius. After performing calculations, it prints all results to the console, followed by the timestamp of execution.

Code Snippet

import java.util.Scanner;


import java.text.SimpleDateFormat;


import java.util.Date;


public class CircleCalculations {


public static void main(String[] args) {


String authorName = "Your Name";


Scanner scanner = new Scanner(System.in);


SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");


Date date = new Date();


System.out.print("Enter the radius of the circle: ");


double radius = scanner.nextDouble();


double diameter = 2 * radius;


double circumference = 2  Math.PI  radius;


double area = Math.PI  radius  radius;


System.out.println("Diameter: " + diameter);


System.out.println("Circumference: " + circumference);


System.out.println("Area: " + area);


System.out.println("Thank you for using the DCA of a Circle application. Time of calculation is " + formatter.format(date));


scanner.close();


System.exit(0);


}


}

Discussion

The program effectively demonstrates the essential calculations involved in circle geometry, applying Java arithmetic and input/output mechanisms. Proper comments and author attribution facilitate code readability and maintainability. The inclusion of program termination with System.exit(0); ensures clean exit behavior, as instructed. Packaging the program into a ZIP file guarantees proper submission per assignment requirements.

Conclusion

This assignment successfully reinforces Java programming fundamentals, specifically in computation, user interaction, and code organization. Adherence to assignment instructions, including proper commenting and packaging, ensures a complete and professional submission. Future enhancements could include graphical user interfaces or additional geometric calculations.
