Write the entire class definition for a Person class that contains the following attributes: Assuming your definition of the Person class is complete in Question 4, in the space below • name - a str value representing the Person's name. • weight - an int value representing the weight of the Person (in Ibs, but this metric is write the definition for a Student class that inherits from the Person class. The Student class must irrelevant for this problem). • contain an additional int attribute named pern. • define its own constructor that takes in a name (str), weight (inti, and perm (int) parameters. For this implementation, you can assume all parameters will be passed in and no default Your class definition should contain the following methods and correct behavior: • A constructor that sets the Person's name and weight to the object. An empty string (*) values are needed. Note: the Student constructor must utilize the Person constructor in order to set the nane and weight values…

Create a UML Class Model based on the requirements . Your Class Model is to include: All classes Attributes and Attribute Types Associations Multiplicity Primary and Foreign keys Any Inheritance, Composition or Aggregation. Building Maintenance system. A rental property management company wants to develop a ‘Building Maintenance System.’ This system will be used by the company to manage maintenance requests from tenants in the several rental buildings that it manages in the city. Each building has a maintenance manager. The maintenance manager is responsible for creating accounts in the system for each tenant in their building. A tenant can rent multiple apartments within the same building. Tenants can submit maintenance requests using this system. Each maintenance request will have a request ID, category, and description. The maintenance manager manages a maintenance crew in their building. Maintenance crew members can be members of more than one maintenance team. Maintenance crew…
In this exercise, you have to perform composition between the Toyota class and its Engine! Problem Statement# You have to create a Toyota class which inherits from a Car class, and is composed of an Engine Note: You already know that in such a composition relation, the oyota class will be res ible for Engine's lifetime. Consider this diagram for reference Car - id: int model: String - color: String + carFeatures(): void +setModel(): void + setColor(): void Toyota ToyotaEngine **** start): void stop): void . ..... + setStart(): void Part of- Car, Toyota and ToyotaEngine: Class Representation You should implement the Toyota class as the child class of the Car. It should have an instance of ToyotaEngine and a setStart() function which in turn calls the start () function of the ToyotaEngine class. The start () and stop () functions of ToyotaEngine class simply print out on screen that the engine has been started/stopped.

Generate a detailed UML class diagram starting from the following problem description: define the required classes, their attributes, the signature of their methods and the relations between the different classes. Problem description: After decades of working with paper records and a personal check-in in the mornings, the daycare ,,Little Caterpillar" wants to digitize their child registration system, and partially automate the check-in process for children. To establish requirements, they have provided their implementation partner with the following information: Parents need to be able to register their children at the daycare when first signing up for their services. Furthermore, they need to be able to drop them off in the mornings, pick them up in the afternoon, and notify the daycare about illness - with the latter feature in particular being highly relevant to the daycare to reduce caller volumes throughout the early morning. Children can be registered either as babies or as…
