Question

URGENT

Preliminary Notes: You have 4 hours to submit your solution. No late submission is accepted. Do not leave your submission to the last minute. You are not allowed to copy any code from anywhere. Your code will be checked by a software for similarity. Implement the code on your own and never share it with someone else. A test code is provided below. Make sure you compiled your code and tested with the given main() function below to see if it is correct. No questions are allowed. Please do not ask any questions by email or any other means. Answer questions as you understood. Make assumptions if you think something is not clear and write your assumptions as comments. If you have any note or explanations, write that in your code as a comment. Put all of your classes (.java files) under a folder(package) named with your name and student id (for example: Alicelik198322344). Zip it with the same name as the folder name. Submit the zip file. The Question: You are supposed to implement some classes related with a milk delivery company. The company has a number of milk trucks (MilkTruck) that are delivering the daily demand of the city. There are different addresses (ie a streets in the city) that the trucks need to visit every day. At each address there are one or more customers. (Customer). The company stores the list of customers in a book (CustomerBook). Each customer has a daily milk demand. There is also a map (Map) that contains the list of all addresses to be visited and the distances between each address. The company has two types of milk truck: The first one is random-traveler milk truck and the second is nearest-address-first milk truck. Implement the following classes with at least the listed methods and members below: 1. Customer: Each customer has a name and address as text value. (String). It also stores the daily demand of the customer as double Methods: Constructor: initializing the members to the given parameters. • Getter/setter: for all members toString(): converts the customer into string as : name - address (dailydemand) 2. CustomerBook: It contains an ArrayList of Customer objects. • Constructor: taking no parameter and initializing the list as an empty arraylist. • addCustomer(): Takes the customer as parameter and adds it to the list.
