- Overriding a superclass function means we can change the throws clause. Is this possible?For the programming language JavaAssume you have a method that expects an object of the superclass to be provided as an argument. This time, instead of a superclass object, you should provide it. Is it OK if I ask? Is there a reason for this or not?
- You have a method which requires an argument of type superclass. It will function if you supply a subclass object rather than a superclass object. Is it permissible? What is the purpose?1. Creating overloaded methods with identical sets of parameters and different return types result in compilation errors. Overloaded methods must have different sets of parameters- also known as signatures. Is it True or False? 2. Attempting to modify a final instance variable after it is initialized is a compilation error. Is it True or False? 3. A subclass can effect state changes in superclass private members only through public, protected methods provided in the superclass and inherited into the subclass. Is it True or False?This is for java
- We may alter the throws clause by overriding a superclass function. Is such a thing even possible?Answer with True or False for the following. Explain your answers.-It is legal to write a method in a class which overloads another method declared in the same.-It is legal to write a method in a superclass which overrides a method declared in a sub-class.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…

Take a picture and submit within the allocated time limit. Problem 1: Implement class Employee as illustrated below. Apply appropriate constructors, encapsulate, and override toString and equals. Student Course Problem 2: «interface Payable abstract Employee Person SalariedEmployee Idno Name Employee Superclass Department Salary Subclass getPayment Amount() firstName, lastName, SSN weeklysalary Given the class hierarchy: 1. Define the interface Payable. 2. Define the class Employee that implements Payable and encapsulate. 3. Define SalariedEmployee and encapsulate. Implement getPayment Amount(). getPayment Amount() - returns a double amount that must be paid for an object of any class that implements the interface. For SalariedEmployee, it would just return the value returned by getWeeklySalary(). for new files: 128MBExercise (Section 30/40): Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An appointment has a description (for example, "see the dentist") and a date. Write a method occursOn(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Give the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.
