Case Study The Covid 19 Global Pandemic Had Changed And Affected Our

Case Study: The COVID-19 global pandemic had changed and affected our day-to-day lives, including our health, careers, social activities, etc. Since the start of the outbreak in the first quarter of 2020, many countries implemented lockdowns to contain the spread of COVID-19, enforcing restrictions on outdoor and social activities involving human interaction. In Singapore, instead of a lockdown, the government implemented the “Circuit Breaker” with three phases, gradually easing restrictions from Phase One to Phase Three, contingent on certain health and safety measures. On 9 May 2020, tripartite partners—the Ministry of Manpower (MOM), the National Trades Union Congress (NTUC), and the Singapore National Employers Federation (SNEF)—issued an advisory on Safe Management Measures for employers preparing to resume operations. Digital solutions such as the TraceTogether app and SafeEntry were introduced to help businesses implement these measures. Additional measures are detailed on official government websites, including the Infocomm Media Development Authority (IMDA).

Your assignment is to develop a Java application to enable effective management of multiple digital solutions used for implementing Safe Management Measures. The application should be built in an Integrated Development Environment (IDE), following detailed specifications below.

Introduction

The COVID-19 pandemic profoundly altered everyday life worldwide, prompting governments to implement various measures to control the virus’s spread. Singapore's response, notably the 'Circuit Breaker' phases, utilized digital solutions to enforce safe management practices. Developing a Java application to streamline management of these digital measures is essential for organizations adapting to these changes. This project involves creating three interconnected classes: DigitalSolutionsCategory, DigitalSolution, and DigitalSolutionsManagement, with functionalities such as data handling, user interaction, and error checking.

Methodology

1. Study and Data Collection

Extensive research was conducted on available digital solutions provided by the Singapore government, notably through the IMDA website, including TraceTogether and SafeEntry. Data was extracted and organized into a structured text file, capturing key solution features such as Name, Description, Vendor, and Solution Category.

2. Java Class Design

DigitalSolutionsCategory Class

This class manages categories of digital solutions, maintaining a list of DigitalSolution objects. It includes methods to add, remove, retrieve solutions, and determine categories with the highest or lowest number of solutions.

DigitalSolution Class

This class models individual digital solutions, encapsulating data points such as ID, Name, Vendor, and Solution Category. It ensures each solution has a unique ID and provides constructors and getter/setter methods.

DigitalSolutionsManagement Class

As the main class, it initializes categories, loads data from external files, and provides functional menus for inserting, retrieving, and removing solutions. It implements robust error handling and ensures data consistency when saving updates back to files.

Implementation Details

Code was developed in Java using the IDE Eclipse. Key functions include input validation, duplicate detection for solution IDs, category management, and file I/O for data persistence. Error handling features involve catch blocks for IOExceptions and validation checks for user inputs.

Sample Code Snippet

public class DigitalSolutionsCategory {
private String solutionCategory;
private ArrayList<DigitalSolution> digitalSolutionList;
public DigitalSolutionsCategory(String category) {
this.solutionCategory = category;
this.digitalSolutionList = new ArrayList<>();
}
public boolean addDigitalSolution(DigitalSolution ds) {
if (digitalSolutionList.size() >= MAX_CAPACITY) {
return false;
}
if (digitalSolutionList.contains(ds)) {
return false;
}
digitalSolutionList.add(ds);
return true;
}
public boolean removeDigitalSolution(DigitalSolution ds) {
return digitalSolutionList.remove(ds);
}
public DigitalSolution getDigitalSolution(String name) {
for (DigitalSolution ds : digitalSolutionList) {
if (ds.getName().equalsIgnoreCase(name)) {
return ds;
}
}
return null;
}
// Additional methods for highest and lowest counts
}

Results and Conclusion

The Java application facilitates efficient management of digital solutions, enabling organizations to keep accurate records and ensure compliance with safe management measures. Error handling mechanisms improve robustness, preventing crashes due to invalid user inputs or file errors. Future enhancements could include GUI interfaces, real-time data synchronization, and integration with live databases for scalability.
