WeatherWeb

The website shows current weather and forecast weather by entering the city name.

• Using jsp, servlet.
• Using OpenWeatherAPI

#Environment:

• jdk 8

• Kotlin/Java Library for OpenWeatherMap.org Weather APIs: owm-japis-2.5.3.0.jar

Use open weather map api:

• we must get a API Key from: https://openweathermap.org/ (free/pro)
• Write your code as such:

1. Create and initialize object {obj1} of "OWM" class or "OWMPro" class
2. Call this object's {obj1} functions to get the desired weather data (such as current weather, daily forecast, etc.). The data is returned as a new object {obj2} of a compatible class based on the type of asked/retrieved weather data (current weather data comes in a different class's object than daily forecast data).
3. Call this returned object's {obj2} functions to get the required information from the collective weather data (like humidity, temperature, pressure, wind speed, etc.).
