Description
Part A Project Brief: Vacoliday
Vacoliday is a touristic company that offers high-end, highly-customizable holidays, with a great emphasis on localness and well-being, in Vacomedita, a lovely town on the Mediterranean coast. Vacoliday has several residences around the town of Vacomedita which they use to accommodate holidaymakers. These residences offer two types of bookable accommodation: fully-integrated apartments and stand-alone rooms.
The apartments are typically larger with one or more bedrooms and other rooms like kitchens, bathrooms, washing rooms, dining rooms, and lounges. The standalone rooms are essentially bedrooms with possibly an en-suite bathroom.
The company offers various attractive meal options that can also be booked. Collective meals can be taken at specific times at one of the stylish dining suites available at the Vacoliday residences. However, meals can also be delivered to people’s accommodation, if pre-booked in advance.
Besides, Vacoliday offers a wide range of exciting bookable experiences. These experiences can take place on-site at a specific residence or off-site, out and about the area surrounding Vacomedita. There are three main kinds of on-site experiences: fitness classes (such as yoga, pilates, or any other well-being physical activities) under the guidance of a fitness instructor; craft workshops during which Vacoliday customers can learn a local craft with a workshop instructor; and cooking classes for which holidaymakers are taught how to prepare local dishes by a chef.
On the other hand, offsite experiences are led by a guide and come mainly under two broad categories: excursions to places of interest and walking hikes. Thus, hikes are on foot and involve walking in the countryside or wilderness around Vacomedita. Excursions are run by a driver on a bus and allow the visiting of places of interest, beauty spots, and other landmarks across the stunning Vacomedita region.
In terms of staffing, Vacoliday relies on highly-trained employees with well-defined roles. Guides oversee all off-site experiences. Drivers use their buses to accompany people on excursions. Chefs take care of meals but also teach cooking classes. Housekeeping attendants are responsible for the good maintenance of their allocated accommodations. Finally, instructors come under two groups: the fitness instructors who run the exercise classes for well-being and the craft instructors who lead and deliver the workshops in which people learn exciting local craft skills.

![Emergency Response Planning You are responsible for planning emergency response routes for a city. The city is represented as a graph, with intersections as nodes and roads as edges. In the event of an emergency, you need to find the shortest path from a central emergency command center to various locations in the city to minimize response time. The city's road network is represented as an undirected weighted graph, where each road has a known travel time (weight) associated with it. Your task is to find the shortest paths from the central emergency command center (Node F) to all other intersections in the city. Your code should return a nested list of [Source, Target, Duration]. Example: [[F, C, 2]]](https://gotit-pro.com/wp-content/uploads/2023/10/c150e24f-eb6a-4e13-a47f-5bc50d4fda18.jpg)
![Modify your assignment submission code to answer the following questions: 1. Create an interface StudentModel for the student model to store student data you wish to keep unchanged such as studentID and StudentEmail. Modify the existing Student class to implement StudentModel and convert it to an abstract class with the reportReport and deleteStudent as the abstract methods. 2. Consider the following two implementation options for student search for Array and ArrayList respectively. Implement a search without a for loop, you may use methods within the two data structures to optimize the code. public void searchStudent(String searchID) { int foundIndex = findStudentByID(searchID); if (foundIndex != -1) { System.out.println("Student found:"); System.out.println("Student ID: " + studentIDs[foundIndex]); System.out.println("Student Name: " + studentNames[foundIndex]); System.out.println("Student Email: " + studentEmails[foundIndex]); System.out.println("Student Course: " + studentCourses[foundIndex]); } else { System.out.println("Student with student ID " + searchID + " was not found."); } } private int findStudentByID(String searchID) { for (int i = 0; i < studentCount; i++) { if (studentIDs[i].equals(searchID)) { return i; } } return -1; }](https://gotit-pro.com/wp-content/uploads/2023/10/6391b22d-2a52-409f-a111-f25c8a39642d.png)
