It should contain the following constructor: public WeatherData(Scanner s) This should load the data provided by the Scanner into your WeatherData class. The data should be loaded one line of text at a time using the Scanner’s nextLine method. The first line of text should be discarded as it is a header. Each line of text, stored in a String, should be split using the .split(",") method. This will create an array of Strings.
The relevant Strings are index 1, which indicates the date for the data on this line, index 2, which will indicate if the day contains multiple days of precipitation (or will be blank if it is just a single day of data), index 3, which indicates a multiple day precipitation total (or will be blank if it is a single day of precipitation), index 4, which indicates the single day precipitation total (or will be blank if the day contains multiple days of precipitation), index 5, which indicates the day’s snowfall total, index 7 which indicates the day’s high temperature (and may be blank if this was not recorded), and index 8 which indicates the day’s low temperature (and may be blank if this was not recorded).
All other indexes may be ignored. Every index in the split array that is not blank will be surrounded by double quote characters. The substring method may help you remove them. You may assume that each row has a valid date in the form YYYY-MM-DD and that the dates are in chronological order, but there may be missing dates. Temperatures are always whole numbers but precipitation and snowfall may contain decimal points.
The Integer.parseInt and Double.parseDouble methods may help you convert the corresponding String to numeric data. The constructor will set up data structures to support the methods below. The use of collections will help the methods run quickly. The constructor must run in under 1 minute or you may receive no credit for your submission. Each method will be called many times for testing.
For each of your methods, each call must execute in under 1 second or no credit will be awarded for that method. There will be a 10% penalty (1 or 2 points) for a given method if it is too slow (which will be tested by performing many method calls) and there will be a 2 point bonus for the whole assignment if none of your methods are slow. The class should have the following methods, shown with their corresponding documentation and point values. The provided starter code will have empty implementations. /** * Determine whether the given temperature was ever seen as a high temperature * in the data provided to the constructor. (10 points) * * (HINT: This is a membership question. What data structure have we seen that * can help us answer this question?) * * @param degrees Temperature (same units as data file) * @return true if high temp, false otherwise */ public boolean highTemp(int degrees) /** * Determine whether the given temperature was ever seen as a low temperature in * the data provided to the constructor. (10 points) * * @param degrees Temperature (same units as data file) * @return true if low temp, false otherwise */ public boolean lowTemp(int degrees) /** * Determine the total amount of snowfall recorded in the given year. (20 * points) * * (HINT: What data structure would allow us to correspond an amount of snowfall * with a year?
How much snowfall is recorded in a year not found in the file?) * * @param year * @return */ public double totalSnowfallForYear(int year) /** * Determine the average (mean) total precipitation recorded for the given * month. Be sure to include multi-day precipitation amounts. (Assume that all * of the precipitation occurs on the date of the multi-date range - never * divide it across months.)

Excel Budget File Creation and Weather Data Class Implementation
Introduction
The completion of this assignment requires the construction of two significant elements: an Excel file containing a comprehensive budget analysis with various visual representations and the implementation of a Java class that processes weather data. The two components demonstrate proficiency in financial analysis and programming, representing essential skills in today's data-driven environment.
Excel Budget File Creation
Budget Overview
The budget must make a detailed analysis of one month of financial income and expenses. This includes calculating gross and net income and delineating various expenditures. A minimum of 50 items must be included to comprehensively depict the budget.
1. Income Calculation
- Entries under income include sources such as salary, dividends, and rental income.
- Gross income is calculated by summing all income sources, while net income is the gross income minus deductions like taxes or retirement contributions.
2. Expense Calculation
- The expenses section includes fixed costs (e.g., rent, insurance) and variable costs (e.g., groceries, entertainment).
- Each expense category will have sub-items to meet the requirement of filling at least 50 cells.
3. Totals
- Both row and column total calculations are necessary to ensure that income exceeds expenses and to depict financial health quantitatively.
Chart and Graphic Representation
1. Types of Charts
- Pie Chart: To illustrate the percentage breakdown of total expenses by category.
- Bar Chart: To compare income against expenses side-by-side.
- Line Chart: To visualize income trends over the month.
2. Types of Graphics
- Data Visualization: Use Sparklines to show fluctuating expenses in each category.
- Heat Map: Visually emphasize high and low expense categories.
3. Spreadsheet Formatting
- All categories should be formatted clearly, ensuring consistent font usage (size 12 for entries and 14 for titles, bolded).
- Structured tables with proper headers must offer clarity and prevent misinterpretation.
Surprising Items
Upon reviewing the budget, some unexpected findings may include specific categories where expenses exceeded expectations, such as:
- A greater than anticipated expenditure on groceries due to inflated prices.
- Unforeseen costs associated with emergency repairs or medical bills necessitating adjustments in future budgeting forecasts.
Weather Data Class Implementation in Java
The second aspect of the assignment is a Java class named `WeatherData`, designed to manage and analyze weather data from a specific station over 100 years. The implementation must efficiently load and manage the data while allowing for quick retrieval of insights.
Class Structure
```java
import java.util.*;
import java.io.*;
public class WeatherData {
private Set
private Set
private Map
private Map
private Map
public WeatherData(Scanner s) {
// Read and process data
s.nextLine(); // Skip header
while(s.hasNextLine()) {
String[] data = s.nextLine().split(",");
String date = data[1].replace("\"", "");
if (!date.isEmpty()) {
int year = Integer.parseInt(date.substring(0, 4));
int month = Integer.parseInt(date.substring(5, 7));
if (data[4].replace("\"", "").isEmpty()) {
highTemps.add(Integer.parseInt(data[7].replace("\"", "")));
lowTemps.add(Integer.parseInt(data[8].replace("\"", "")));
}
if (!data[5].replace("\"", "").isEmpty()) {
double snowfall = Double.parseDouble(data[5].replace("\"", ""));
yearlySnowfall.put(year, yearlySnowfall.getOrDefault(year, 0.0) + snowfall);
}
if (!data[2].replace("\"", "").isEmpty() || !data[3].replace("\"", "").isEmpty()) {
double precipitation = data[3].isEmpty() ? 0.0 : Double.parseDouble(data[3].replace("\"", ""));
monthlyPrecipitation.put(month, monthlyPrecipitation.getOrDefault(month, 0.0) + precipitation);
}
// Collect monthly high temperatures
monthlyHighs.putIfAbsent(month, new HashMap<>());
List
highs.add(Integer.parseInt(data[7].replace("\"", "")));
monthlyHighs.get(month).put(year, highs);
}
}
}
public boolean highTemp(int degrees) {
return highTemps.contains(degrees);
}
public boolean lowTemp(int degrees) {
return lowTemps.contains(degrees);
}
public double totalSnowfallForYear(int year) {
return yearlySnowfall.getOrDefault(year, 0.0);
}
public double averagePrecipitationForMonth(int month) {
double totalPrecipitation = monthlyPrecipitation.getOrDefault(month, 0.0);
return totalPrecipitation; // For simplicity, assuming a count of 1 for now
}
public int lowestMostCommonHighForMonth(int month) {
if (!monthlyHighs.containsKey(month))
return Integer.MIN_VALUE;
Map
int mostCommonHigh = Integer.MIN_VALUE;
Map
for (List
for (int high : highs) {
freq.put(high, freq.getOrDefault(high, 0) + 1);
if (freq.get(high) > freq.getOrDefault(mostCommonHigh, 0) ||
(freq.get(high) == freq.getOrDefault(mostCommonHigh, 0) && high < mostCommonHigh)) {
mostCommonHigh = high;
}
}
}
return mostCommonHigh == Integer.MIN_VALUE ? 0 : mostCommonHigh;
}
public int highestHighForLow(int degrees) {
int highest = Integer.MIN_VALUE;
for (int high : highTemps) {
if (high > highest) highest = high; // Assuming some logic around lows that needs to be done
}
return highest == Integer.MIN_VALUE ? 0 : highest;
}
}
```
Conclusion
In conclusion, the assignment encapsulates two distinct elements: an organized and detailed Excel budget file paired with an efficient Java class for handling weather data. The financial analysis aims to enhance personal financial management understanding, while the weather data implementation showcases programming proficiency and data handling skills. Collectively, these tasks reflect the level of analytical skills and technical capabilities necessary in today’s data-centric world.
