Write a java program in which 1. Implement all these classes while illustrating the concept of aggregation and composition in terms of ownership and life-cycle. Consider six classes i.e. Person, Department, Laboratory, and University having following specifications. Class University has • Two attributes of type string i.e. universityName and location • An attribute named dept of type Department Class Department has • Two attributes i.e. deptID, deptName • A two-argument constructor to initialize data fields with user-defined values • A member function display() to show all attribute values Class Laboratory contains • Two attributes i.e. labID and experimentNo • A two-argument constructor to initialize data member with user-defined values Class Person has • Two attributes i.e. name and age • A parameterized constructor to initialize attributes with user-defined values • A member function display() to show its attribute values

We have a parking office class for an object-oriented parking management system using java Add(implement) a method to the Parking Office class to return the collection of permit ids for a specific customer (getPermitIds(Customer)) using java I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....). N.B. Parking office methods in the class definition like register, getcustomer and addcharge have already been implemented, we just need an additional getPermitIds(Customer) method as mentioned above Explain your code in a few words Important- We have a method to return a collection of permit ids (getPermitIds), what we need is a method to return the collection of permit ids for a specific customer (getPermitIds(Customer))
Write a Java program to create a class Cube having attributes width, height and depth. Initialize attributes using a parameterized constructor. Define another class CubeHigh inherited from Cube class to add another attribute weight to the Cube. Also, define required parameterized constructor in CubeHigh class. Lastly, define a class Shipment which is inherited from CubeHigh class which is used to add another attribute cost to the cube. Finally, test everything by creating shipment class objects in main method in a separate class and create at least 3 shipments.

Below we have class diagrams with three classes for a simple java based parking management class. Use the classes below to write java code for classes :a parking observer class (that implements an observer pattern) , a transaction manager class and a parking lot class(subject to the observer). Use the class diagram and java class to implement it. You should use an observer pattern to implement your code.The main goal is to implement the following - Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() method
Write a java program Write a class named Employee with name and salary as private data fields. Add a constructor with both parameters. Write a class named Manager which unherits the Employee class. Add an instance variable, named department, of type String and 15 private. Add a constructor in the subclass class and a toString () method that prints the manager's name, department, and salary [Hint: Add a tastanel) method in the super class as well]. Create objects of Manager and Employee dass
For a parking management system, use the Observer pattern to implement this interaction using Java and implement the three classes mentioned below. Implement a ParkingObserver that has the role of the Observer. The Observable classes (Subjects) will be the ParkingLots. It would be helpful if the notify method in the subjects (and update method in the observers) took a parameter, perhaps an object of type ParkingEvent, which could have fields including the lot, timeIn, timeOut (if relevant), and permit. The ParkingObserver should register with each ParkingLot and receive the messages. Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() method. Based on these requirements you should implement three actor classes in this interaction using java: TransactionManager, ParkingObserver and ParkingLot. 1. The…

Write a JAVA program to model the kinds of people one finds in a university. The categories are students, teachers and teaching assistant (TAs). All these categories are kinds of Person (Person is abstract class. A teaching assistant (TA) is a student and a teacher as well. A person has a name (string). A student has grade point average GPA (between 0 to 4), the teacher has the number of scholarly papers he/she has published and the teacher assistant has the number of courses he/she assists. All the classes contain constructors with default arguments to fill all data spaces. Provide display method to print all data members of an object on the screen. Classes also contain a function called isSuccessful(). Students with a GPA over 3.5 are considered successful. This function returns true if someone is successful or false if not. In main(), define an array of Person class, which can point to students, teachers and teacher assistants. The program first asks the kind of person and then lets…
