1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.
Urgent Quick Question Write an equals method for the StepsFitnessTracker class that tests whether the one object is equal to another object that is passed as an argument (Object otherObject). The Object superclass provides an equals method that tests if two object references are equal. Your new equals method should override the Object equals method, and should test the following: • Return true if the current (this) object, and otherObject are identical references (hint: you can use the == operator for this). • Returns false if otherObject is null. • Returns false if the current (this) object and otherObject have different classes (hint: you can use the getClass() method provided by the Object superclass, see the Java 8 API documentation for details). • Casts otherObject to a StepsFitnessTracker, and tests for equality of each instance variable1 , if the instance variables are the same the method should return true. Now write an equals method for the DistanceFitnessTracker and…

a. Write a class named Student has the following data fields and methods: private int Id private double GPA Constructor to create a Student object with specified name, address, Id and GPA. Accessors and mutators methods for Id and GPA data fields (get and set). A method toString () that returns Id, name and address and GPA. b. Write a test program that creates a Student object with Id:123 Name: Ahmed address: Muscat grade: 2.55 & then call toString () method to display Id, name and address and GPA.

Create an AlienType class. Include at least three protected data members of your choice, such as the number of eyes the Alien has. Include a constructor that requires a value for each data field and an output method that returns a String containing a complete description of the Alien. Save the file as AlienType.cpp. Create two classes—MartianType and JupiterianType—that descend from Alien. Supply each with a constructor that sets the Alien data fields with values you choose. For example, you can decide that a Martian has four eyes but a Jupiterian has only two. Save the files as MartianType.cpp and JupiterianType.cpp.Create an application that instantiates one Martian and one Jupiterian. Call the output method with each object and display the results. Save the application as CreateAliens.cpp.
TOPIC: Inheritance In Python, modify the given code based on the given specifications below. Create another class, “Food.” For the Food class, the specifications are: The object will have the following attributes on initialization: weight (weight of the food in kg) energy_add (amount of energy it will add once consumed) happiness_add (amount of happiness it will add once consumed) Modify the Child and the Friends classes such that: Instead of accepting a string (as food) in the eat method, the method should accept a Foodobject Once a Child/Friendsobject eats a Food object: The added weight should be the Food object’s weight The added energy should be the Food object’s energy_add The added happiness should be the Food object’s happiness_add The given code (can also be found on the picture): class Child: def __init__(self, child_number: int, name: str, weight: float): self.child_number = child_number self.name = name self.weight = weight def…

Write a class called Alien. The Alien class must have one field of type String called name, one of type String called planet and one field of type boolean called humanoid. Write one constructor that takes three parameters to initialise all of these fields. The parameters must be passed in the order name, planet and humanoid status. IntelliJ hint (this won't be in the real test): put your cursor after the last field; right-click, choose Generate, choose Constructor, select the fields that are set via parameters and click Ok. Check that the constructor is correct. Write a getter method for each field. IntelliJ hint (this won't be in the real test): put your cursor after the closing curly bracket of the constructor; right click, choose Generate, choose Getter, select all of the fields; click Ok. Check that the you have three getters. Do not write setters methods. Write a method called getDetails that will return the values of the fields in one of the following two formats. For example,…
Write a Triangle class which has members: side1, side2 and angle with appropriate data types forthem. Also write a constructor function that takes 3 parameters to initialize these fileldmembers.
Create a class named 'Member' having the following members: Data members 1 - Name 2 - Age 3 - Phone number 4 - Address 5 - Salary It also has a method named 'printSalary' which prints the salary of the members. Two classes 'Employee' and 'Manager' inherits the 'Member' class. The 'Employee' and 'Manager' classes have data members 'specialization' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a manager by making an object of both of these classes and print the value you assigned.
a) Create an enumeration named Departments that contain four set of values FINANCE, HR, IT, and MARKETING.b) Create a class named PersonDetails that contains fields for a person’s first name (String), last name (String), and address (String). The class have- A constructor that accepts parameters for each field.- Get methods for each field.c) Create a class named Employee that contains fields for an employee ID (int), Social Security number (String), personal information (Person object), department (Departments type), and annual salary (double). The class have- A constructor that requires values for each data field.- Get methods for each of the data fields.- Set methods for each of the data fields.d) Create an application/class named EmployeeSort that allows a user to enter values for an array of 5 Employee objects (create an array of Employee type that will save 5 employee objects). Prompt a user for the data needed to create an employee object. Continue to prompt the user for Social…
