Section 5.4 Stretch Level

This Java program analyzes the temperatures recorded in Winnipeg, Manitoba from April 1, 2024 to April 10, 2024 and it contains methods that perform various temperature-related calculations.

  class DayTemperature{

    String day;
    double minTemp;
    double maxTemp;

    public DayTemperature(String day, double maxTemp, double minTemp){
        this.day = day;
        this.minTemp = minTemp;
        this.maxTemp = maxTemp;
    }

    public String toString(){

    }

    public double getAverageTemp(){

    }
}
The DayTemperature class represents a single day’s temperature data. This includes:
  • day (String) to store the day of the temperature record (e.g., "April 1, 2024")
  • minTemp (double) to store the minimum temperature recorded for the day.
  • maxTemp (double)to store the maximum temperature recorded for the day.
  public class TemperatureAnalysis{
    //TO-DO: Initialize static ArrayList titled weekTemp that holds instances of DayTemperature

    public static void main(String[] args){
        printWeekTemp();
        printAverageWeeklyTemp();
        printHighestTemp();
        printLowestTemp();
    }

    public static void printWeekTemp(){
      
    }

    public static void printMedianTemp(){

    }

    public static void printAverageWeeklyTemp(){
     
    }

    public static void printHighestTemp(){
   
    }

    public static void printLowestTemp(){

    }
The TemperatureAnalysis class manages the recorded weather data by performing calculations such as calculating averages and extreme temperatures.

Subsection 5.4.1 Instructions

  1. Implement the toString() method in DayTemperature
    • E.g., April 1, 2003 -- Min: -7.8°C, Max: 6.2°C
  2. Implement the getAverageTemp() method in DayTemperature which calculates and returns the average temperature for the day (average of max and min temperatures)
  3. Define a static ArrayList named weekTemp inside the TemperatureAnalysis class to store instances of DayTemperature
  4. Implement the following methods inside TemperatureAnalysis:
    • printWeekTemp()method prints the temperatures recorded for each day of the week
    • printAverageWeeklyTemp() calculates and prints the average temperature for the entire week by calculating the daily averages, summing it up and dividing by the total number of days
    • printHighestTemp() locates and prints the day with the highest temperature recorded for the week
    • printLowestTemp() locates and prints the day with the lowest temperature recorded for the week
  5. Bonus: Implement a printMedianTemp() method that calculates and prints the median temperature of the week
The expected output is:
Daily Temperatures for the Week:
April 1, 2024 -- Min: -7.8°C, Max: 6.2°C
April 2, 2024 -- Min: -2.0°C, Max: 2.0°C
April 3, 2024 -- Min: -4.3°C, Max: 7.9°C
April 4, 2024 -- Min: -3.3°C, Max: 10.1°C
April 5, 2024 -- Min: -2.1°C, Max: 12.5°C
April 6, 2024 -- Min: 3.0°C, Max: 14.1°C
April 7, 2024 -- Min: 1.6°C, Max: 15.6°C
April 8, 2024 -- Min: 0.4°C, Max: 11.0°C
April 9, 2024 -- Min: -2.1°C, Max: 13.8°C
April 10, 2024 -- Min: -0.2°C, Max: 16.2°C
Average Temperature: 4.630000000000001°C
The median temperature is: 5.45°C
The day with the highest temperature is: April 10, 2024 -- Min: -0.2°C, Max: 16.2°C
The day with the lowest temperature is: April 1, 2024 -- Min: -7.8°C, Max: 6.2°C
