Question

In this assignment you will be implementing a weather forecaster. It involves writing 3 different classes plus a driver progrThe Season Class The first, shortest, and easiest class you should write is the Season class. This class represents a seasonThe Season Class, continued PLEASE NOTE: The Sample Interactions Tab Test Code would be entered into the Interactions tab iThe Temperature Class The next class you should write is the Temperature class. This class represents a temperature and shoulThe Temperature Class, continued Here are brief descriptions of all of the methods you should implement for the Temperature cThe Temperature Class, continued even more Method Description Sample Interactions Tab Test Code setScale(sc) Sets the scale;The Weather Class It depends on the Temperature and This class represents weather and should be saved in the file Weather.javThe Weather Class, continued Here are brief descriptions of all of the methods you should implement for the Weather class. MaThe Driver Program: Forecaster.java After these three classes have been developed, you also need to write a program with a maIf the season for the Weather object is summer : Output Requirements The forecast is steamy The temperature is 32° C or above
