Computer science question

Solved in 2 steps
- Create the following classes based on the given declaration. Also, each class should have the default constructor. Just place the prototype of the constructors in the class but you dont have to implement them. The default constructor is a public member. A) CSUSM is an object of class University. Class University has the follow private attributes: -UnivName: string -UnivDepts: a vector of Department class -UnivStudents: a vector of student class -UnivAddress: string -UnivAge: int B) Each department has the following private attributes: -deptName: string -deptFaculty: vector of Faculty class -deptYearCreated: int C) Each student has the following private attributes: -studName: string -studYearOfStudy: int -studNumber: long -studCoursesTaken: vector of Course class D) Each faculty has the following private attributes: -FacName: string -FacYearofExperience:int -FacId: long -FacCoursesTeaches: vector of Course Class E) Each course has the following private attributes:…In this problem, we are going to use ArrayLists and classes to design a road trip. You have three classes: GeoLocation.java which represents a geo location. A RoadTrip.java class, which represents a road trip (or an ordered list of places), and a RoadTripTester.java class which brings them all together. In GeoLocation.java: Add a private instance variable called name which is a String. This represents the name of the location. Modify the Geolocation class constructor so that it is now of the format public GeoLocation(String name, double theLatitude, double theLongitude) Add a getter method for name called getName(). Update the toString so that it returns a String of the format San Francisco (37.7833, -122.4167) Now, you’ll also need to create a RoadTrip class. RoadTrip stores an ordered list of locations, so you’ll need to have an ArrayList as an instance variable. The RoadTrip class constructor should initialize an ArrayList that stores a list of GeoLocations. You’ll also need to…In Java The base class Pet has protected fields petName, and petAge. The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.
- use java to write code and please use treeset as mentioned in the question Create a class Customer with below attributes: int - id String - name String - dob double - salary String - email int - age Make all the attributes private.Create corresponding getters and setters. Create a constructor which takes all parameters in the above sequence. The constructor should set the value of attributes to parameter values inside the constructor. Create a class CustomerDemo with main method Create a static method sortCustomerOnId in the CustomerDemo class. This method has to take a list of Customer objects and return a TreeSet of Customer objects sorted based on id. Call the above method from the main methodConsider this scenario, a mehtod in some class needs to access a data field in another class, here are two possible implementations: public class Process { /* * Check if student qualifies for financial help */ void check(Student student) { //.... } /* * Check if student qualifies for financial help */ void check(double studentGPA) { //.... }} In class Process, which check method you think is better, why? In other words, should we pass the object to the method or just the data member it needs? Disucuss the Pros and Cons of each approach (if any). Assume class Student has a mehod called getGPA( ).The Java Programming class has two types – remote and in-person. For remote students, the weighted score comprises of midterm, final, assignments and discussion. The weights for each are 30%, 30%, 30% and 10% respectively. For in-person students, the weighted score comprises of midterm, final and assignments. The weights for each are 30%, 30% and 40%. Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method…
- Create a Person class that has the properties: name and age. Override toString so that it displays a Person object like this: Where name is the value of the name property and age is the value of the age property. "<Name: name, Age: age>" Person class should have a natural ordering by age in descending order. Create a Main.java file that: Sorts a List of people using Person’s natural ordering. Uses a custom Comparator with an anonymous class that sorts the List of people by name in ascending order. Uses a custom Comparator with a lambda implementation that sorts the list of people by name in descending order.Write a Java class Student inherited from Person class. Your class must have the following features: Student - major: String + Student() + Student(name: String, id: int, major: String) + getMajor(): String + Override toString() method: you have to return needed data Fields values. Note: major data members can take only CS for Computer Science, CIS for Computer and Information Systems, CPE for Computer Engineering, SE for Software Engineering, and NES for Network Engineering and Security.1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…
- Answer the given question with a proper explanation and step-by-step solution. The base class Pet has protected fields petName, and petAge. The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three private fields: first name, last name, and GPA. (Hint: GetGPA() returns a student's GPA.) Ex: If the following students and their GPA values are added to a course: Henry Nguyen with 3.5 GPABrenda Stern with 2.0 GPALynda Robison with 3.2 GPASonya King with 3.9 GPA then the findHighestStudent() method returns a student and the program output is: Top student: Sonya King (GPA: 3.9)Code:Course.java: import java.util.ArrayList; //create class Student //create class Courseclass Courses{ private ArrayList<Student> roster; // collection of Student object // class constructor…Car herCar = new Car();Car hisCar = new Car(); Car myCar = hisCar;hisCar = null;myCar = herCar;herCar = hisCar; suppose the following obejexts created in the class car, How many "null reference" can you see in this code? How many "unreachable objects" can you see in this code, which will be subject to garbage collection? How many "active object reference" can you see in this code? How many "reachable objects" can you see in this code?
