Java problems

Tired of forgetting to perform your daily tasks, you decide it is time to use technology to help you remember. Instead of using a simple to-do list, however, you want your phone to do the job for you and remind you of your tasks whenever your are near the place where they should be done. For instance, you want to be reminded of submitting the PA whenever your are in college, or buy a new notebook when you visit a specic bookstore. Because you can never predict the exact position where you will be, you want the notication to be sent to you whenever your are in the area surrounding the location The class GPS (given to you with this assignment) allows to convert a distance on Earth surface to angles and compute the distance between two points given by latitude and longitude. You may use it if necessary. Your goal in this assignment is to write the core part of this application, which stores and manages notications1. To Achieve this, we proceed in three steps: 1. Write a binary search tree implementation of a map, which has both key and data generic. The data structure also supports range search (nding all keys in a given interval). 2. Choose a representation and storage scheme for notications. 3. Write a class LocNotManager that manipulates the notications hence represented.
