Interfaces for Custom Weather Information Retrieval in Java

Create a Java program to demonstrate the use of an interface for custom weather information retrieval

The WeatherService interface declares a method getWeatherInfo for retrieving weather information.
In the main method of the Main class, an anonymous class is created that implements the WeatherService interface.
Inside the anonymous class, the getWeatherInfo method implements the logic to retrieve weather information. In this example, a mock response is returned indicating sunny weather with a temperature of 25°C for the specified location.
A sample location is provided.
The getWeatherInfo method of the WeatherService interface is called to retrieve weather information for the specified location.
The retrieved weather information is printed to the console.

Source Code

interface WeatherService
{
	String getWeatherInfo(String location);
}
 
public class Main
{
	public static void main(String[] args)
	{
		WeatherService weatherService = new WeatherService()
		{
			@Override
			public String getWeatherInfo(String location)
			{
				// Implement weather information retrieval logic here (e.g., using a weather API)
				return "Weather in " + location + " : Sunny, 25°C";
			}
		};
 
		String location = "New York, USA";
 
		// Get weather information
		String weatherInfo = weatherService.getWeatherInfo(location);
		System.out.println(weatherInfo);
	}
}

Output

Weather in New York, USA : Sunny, 25°C
