Project Title: Weather Data Analysis Program

Background: As individuals, we often need to keep track of weather data for various reasons such as planning outdoor activities, monitoring climate trends, or simply staying informed about local weather conditions. However, manually collecting and analyzing weather data from different sources can be time$-$consuming and inefficient. To address this issue, we propose developing a Java program that allows users to input daily weather data and retrieve statistical information for different timeframes.

Potential Strategy #$1$: Database Approach Advantages:

Efficient storage and retrieval of large datasets.

Easy to query and analyze data.

Scalable for future enhancements.

Disadvantages:

Requires setting up and maintaining a database system.

Complexity in handling database operations.

Potential security concerns with sensitive data.

Potential Strategy #$2$: File$-$Based Approach Advantages:

Simple implementation using text files or CSV$.$

No need for additional database setup.

Easy to distribute and share data.

Disadvantages:

Limited scalability for large datasets.

Slower retrieval times compared to databases.

Risk of data corruption or loss if not handled properly.

Chosen Strategy: File$-$Based Approach

Inputs and Outputs: Inputs:

User$-$entered daily weather data including high temperature, low temperature, and weather condition.

Requests for statistical information over different timeframes $(7$ days, $14$ days, $30$ days$).$

Outputs:

Average temperature and predominant weather condition for the specified timeframes.

Highest and lowest temperatures recorded during the requested timeframe.

Inheritance Hierarchy:

WeatherData $($Parent Class$)$

Attributes: Date, High Temperature, Low Temperature, Weather Condition

DailyWeatherData $($Child Class of WeatherData$)$

Additional Attribute: None

WeeklyWeatherData $($Child Class of WeatherData$)$

Additional Attribute: Average Temperature, Predominant Weather Condition

FortnightlyWeatherData $($Child Class of WeatherData$)$

Additional Attribute: Highest Temperature, Lowest Temperature

MonthlyWeatherData $($Child Class of WeatherData$)$

Additional Attribute: None

Use of Files:

Utilize text files or CSV to store weather data.

Separate files for daily, weekly, fortnightly, and monthly data to facilitate efficient retrieval and processing.

Use of Collections:

Use ArrayList to store weather data for easy manipulation and retrieval.

Testing:

Implement unit tests to verify the correctness of data processing and statistical calculations.

Test edge cases such as empty datasets, invalid inputs, and extreme weather conditions.
