Is there a different way of doing this problem? Question: Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap. Add a function signalStrength that returns the wireless signal strength as a percentage. The signal strength decreases as one moves away from the access point location. Test your class by writing a main function that creates five access…
Assume we have a Book class that includes authorInit and pubYear attributes of type Stringand int, respectively, both set by the constructor. Write a compareTo method for this class, so thatbook objects are ordered based on the author’s initials first and then (if needed) the publication year. DO NOT assume the length of String type authorInit to be 2.
What is the best first step to include in your implementation of equals(Object o) anytime you override it? Group of answer choices 1. Check if all instance variables of the invoking object and the input object are all equal. 2. Cast the passed in object as the class of the object invoking equals. 3.Check for identity (using ==). 4.Check if the invoking object (this) and the passed in object both implement the same interface, using instanceof. 5. No answer text provided.
Question#4: Override the clone() method in the BankAccount class to perform deep copying. Verify your code in the main() method by creating a deep copy of a BankAccount object and displaying that the copied object is equivalent to the original object. public class BankAccount implements Cloneable{ private int accountNumber; private int balance; private Date createDate; // constructor for creating a bank account public BankAccount(int accountNumber, int balance) { this.accountNumber = accountNumber; this.balance = balance; this.createDate = new java.util.Date(); } //deposit money public int deposit(int amount) { balance = balance + amount; return balance; } //withdraw money public int withdraw(int amount)…

Consider 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( ).
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…

This question concerns writing a Student class to model a student's name, composed of a first name, middle name and last name. The Student class should meet the following specification:Class StudentA Student object represents a student. A student has a first name, middle name and last name.Methodspublic void setNames(String first, String middle, String last)// Set the first, middle and last names of this Student object.public String getFullName()// Obtain the full name of this Student with the middle name converted to an initial only.2Thinking of the problem in terms of testing, there are three requirements that must be met:1. The setNames() method sets the names stored in the object i.e. the values of firstName, middleName, lastName.2. The getFullName() method obtains the name of the student with the middle name converted to an initial only.3. The getFullName() method does not change anything – i.e. it does not modify the values of firstName, middleName, lastNameHINT: To start your…
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.
Please complete the following tasks: Write a class “Actor” that contains two attributes with the appropriate level of visibility explicitly defined. “Name” which is a String, Private, “NumberofAwards” which is an integer, private Write a default Constructor for this class that initializes the name to “Bob Smith” , and the number of awards to 0. Write an overload the constructor for this class that accepts actor’s name as a parameter Write accessor methods for each of the attributes. Write a method “winsAnOscar” that increases the number of awards by one and prints “The crowd applauds for <actor’s name>!” Be sure to use accessors where appropriate. Make sure your header is complete, with the appropriate level of visibility and any required keywords.
