(Implementing inheritance and apply the use of keyword super and this)
Assume you have to develop a grading application for grading student's activity. Each
activity will be given a numeric score (0 to 100), and accordingly will be given a grade (A,
B. C. D. or F). The grade is given based on the condition in Table 1 below.
Table 1: Scores and their corresponding grades
Condition
Letter Grade
Score >= 90
A
Score >= 80
В
Score >= 70
Score >= 60
D
Score < 60
F
Create a class name GradedActivity, with an attribute to hold the score for the activity.
The SetScore method sets the score from a given parameter value and the getScore method
returns the score. A getGrade method should retum a grade's letter based on the given
numeric score, according to the rules given in Table 1.
Then create a new class Essay which extends the GradedActivity class. The new class is
to detemine the grade a student receives for an essay based on the accumulated score (0 to
100), which is accumulated based on a…

The class contains: - The data fields hour, minute, and second that represent a time. - A no-arg constructor that creates a Time object for the current time. (The values of the data fields will represent the current time.) -A constructor that constructs a Time object with a specified elapsed time since midnight, January 1, 1970, in milliseconds. (The values of the data fields will represent this time.) -A constructor that constructs a Time object with the specified hour, minute, and second. - Three getter methods for the data fields hour, minute, and second, respectively. -A method named setTime (long elapseTime) that sets a new time for the object using the elapsed time. For example, if the elapsed time is 555550000 milliseconds, the hour is 10, the minute is 19, and the second is 10. Draw the UML diagram for the class and then implement the class.

- (The Person, Student, Employee, Faculty, and Staff classes) Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number, and e-mail address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. Use the MyDate class defined in Programming Exercise 10.14 – see the textbook - to create an object for date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the person's name. Draw the UML diagram for the classes and implement them. Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods.arrow_forward(Data exploration and Mining Method Proposal): Here you will explore your data both visually and/or statistically then propose methods for mining it.

- (Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…arrow_forwardState whether it is true or false and why .arrow_forwardDo not use regular expressions in your solution for this exercise. Write a program that checks to see if an input password is valid or not. In this exercise, a valid password has the following characteristics: It contains at least eight characters. It contains at most 12 characters. It contains only alphabetic characters, digits and the underscore (‘_’) character. It does not start with a digit. It has a mix of upper-case and lower-case characters. Your class must contain the following method: public static String checkPassword(String input) This method receives a possible password as input and returns only the String“OK” if the password is valid. If the password is not valid then you can return the reason(s) for that as the return value. This is not a part of the requirements, however, and you don’t need to do that. You can simply return null for an invalid password.arrow_forward
