Create a JAVA app with

Purpose: Allows teachers to decide if it is e-learning day based on date chosen and in turn lets all users know if kids are going to school physically that day or whether it will be an e-learning day, with minimum 10 classes. Please provide zip file.

A class contains preferences that the teachers can set. These preferences should be stored so that the user does not have to reset these each time a user brings up the app. These settings should have default settings that are displayed when the user first goes into preferences. If the user changes any of these settings, such as dates, these settings should be retained, and any changes should be displayed (along with those settings not changed) when the user returns to the preferences activity.

Another class will allow students to see if it is an eLearning day. Then it will tell students what they need to do with option to enter their classes online.

The app as a whole Help teachers see if it is e-learning day whether for sickness due to student illness, weather issues or school board mandated. School board mandated option will be chosen only by teachers, since students and other users will not have access to that information.
