Heading: Code Execution and Expected Output

The output of the code would look similar to the following text, listing the date/time and weather conditions for the upcoming forecasts:

Date/Time: 2023-04-22 18:00:00
Temperature: 30.5°C
Min Temperature: 29°C
Max Temperature: 32°C
Humidity: 40%
-------------------------------
Date/Time: 2023-04-22 21:00:00

Code Explanation:

This Java program performs the following steps to fetch and display weather forecast data for a specified city:

1. It initializes constants for the API key and the base URL of the weather service.
2. In the main method, it defines the city for which weather data is to be fetched and constructs the full URL for the GET request.
3. It calls the fetchWeatherData method which creates an HttpURLConnection to the weather service endpoint.
4. The fetchWeatherData method sends an HTTP GET request, checks the response code and, if successful (HTTP 200), reads the response into a StringBuilder.
5. The main method then calls parseAndDisplayWeatherData if data retrieval was successful.
6. The parseAndDisplayWeatherData method converts the string into a JSONObject, extracts the list JSONArray which contains weather forecasts for various times.
7. The method iterates over this array, and for each forecast, it extracts temperature, minimum and maximum temperature, humidity, and the forecast date/time from the relevant JSONObjects.
8. It prints these details out in a human-readable format.

This program integrates with the OpenWeatherMap API to fetch weather forecasts specifically adjusted to output temperature in Celsius (metric units). By abstracting the data fetch and parse in separate methods, the program provides clear structure and ease of debugging. Additionally, it handles potential errors in the HTTP request, like an invalid response code.
