+# Weather app assignment
+## Introduction
+In this assignment, we built a simple Java application that connects to a weather API and retrieves information about the current weather conditions of a given city.
+## Design and Implemention
+At first the city's name is passed to the getWeatherData method and it returns a string.Then the string is passed to getTemperature(or getHumidity, etc) method and we can get the information we want.
+## Testing and Evaluation
+To make sure the program works properly, I checked the results with the correct weather information of that city.
+## Conclusion
+This assignment helped me to learn how to use JSON objects.
