Hello everyone!
I have two classes for two different robots and trying to overload the == operator to compare the location of the two different objects of the two different classes. Can you please help?
Step by step
Solved in 2 steps
- Answer both to get a like or don't attempt.Thanks Question: 3. _________is a correct annotation with respect to JUnits.4. Is it necessary to write the test class to test every class? __________Make class Student, you need to add the normal constructor with parameters not default with 5 attributes age, gender, ID full name, date of registration JAVAConsider 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( ).
- Given the following class diagram, interfaces and classes that model various kinds of animals. What will be the errors in the main method? For each error, indicate the line number of each incorrect statement and explain in one sentence why it is wrong.We have two classes, Person and Employee. Both have a field, firstName. We have instances of these objectsPerson p and Employee e. Both p and e have the same value for firstName, specifically, p.firstName = “joe”and e.firstName = “joe” Which of the following statements is necessarily true? Group of answer choices 1. p.equals(e) will return true because they contain the same firstName. 2. We don’t know if either class will have an equals method. 3. There is not enough information to tell what p.equals(e) will return. 4. p.equals(e) will return false but p == e will be true.Is it possible to extend one class which are defined as final? Explain?
- These two pictures are my resource and driver classes. Please, help me with the error in my resource class. I want my resource class to have getName, getSalary, getThePercentageThatTheEmployeeWantToRaise, and calculateTheNewSalary methods. For my driver class, I want the driver class to ask the user to input their name, salary, how much they want to raise, and print out their new salary.Answer the given question with a proper explanation and step-by-step solution. USING JAVA: ---Sorting the Invoices via dates--- Another error that will still be showing is that there is not Comparable/compareTo() method setup on the Invoice class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the Invoice class. The compareTo() method will take a little work here. We are going to compare via the date of the invoice. The dates of the Invoice class are by default saved in a MM-DD-YYYY format. So they have a dash '-' between each part of the date. So you will need to split the date of the current invoice AND split the date of the object sent to the method. We have three things to compare against here. First we need to check the year. If the years are the same then you should go another step forward and compare the months. If the months are the same then you will lastly have to compare the day. Use whatever…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…
- Answer the given question with a proper explanation and step-by-step solution. Using Java Create an BankAccount Class that has an account id number (of type integer), balance (of type double), and rate (of type double) as private data. Add get and set methods for these three variables to work with these attributes. Make overloaded constructors to bring in and set all values, and also to just to bring in a customer name and id which uses 0 for the balance. Include error handling in the set for the balance which throws an exception if a change would put the balance below 0. In Main of another class file create 2-3 objects of BankAccount and work with their values and output them to the user to test your new class. Take the BankAccount Class from above and copy it into this program. You will use it as one of the classes in this one. Create a BankCustomer class with 3 BankAccount objects inside it as private variables (of type BankAccount) as well as a customer name (of type String).…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.For this exercise, you are given a Team superclass with a BaseballTeam and FootballTeam subclass. Take a moment to examine these classes and the instance variables and methods in each. In the TeamTester class, you will see three objects declared and instantiated using the Team, FootballTeam, or BaseballTeam classes. For each object, use a print statement to print out any public method that returns information that is available for that particular object, including the toString. For example, the dolphin object is a FootballTeam object. One of the pieces of information that can be printed is the getTies() method, so you will call that method in your TeamTester file: System.out.println(dolphins.getTies()); Do this for all the methods that each of the objects can call. Hint: Remember, for the program to compile and run, Java looks for methods to exist in certain classes. ================================= public class Team { private String name;private String location;private int…
