- USE JAVA LANGUAGE Create a constructor named Exam that assigns "Good luck" to a previously declared String variable named message. Create an empty overloaded constructor for the Exam class with two (2) String parameters named period and level. Declare a double-type accessor named getPrice that returns the value of price. Declare a boolean-type accessor named isFinished that returns the value of status. Declare a class named Midterm that inherits from the class named Exam. Create three (3) class declarations to show multiple levels of inheritance. Use the classes named Exam, Midterm, and Essay. Create a constructor named Midterm that prints "Exam has started." using println(). Its first statement should be a call to a constructor in the parent class. Given the base class named Quiz and the derived class named Essay, write a statement to show inheritance between these classes.Using Java Create a constructor named Exam that assigns "Good luck" to a previously declared String variable named message.

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 to create an object for the 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 in output statements.Create a program in java Write a class named Employee that has the following fields:• name.

- JAVA Task Write a JAVA class named Account to represent an account that you may find at a bank. Accounts have a balance and an annual interest rate. Include attributes in the Account class to reflect these. Write getters for both attributes and a setter for only the annual interest rate. Think about how real bank accounts work, you change your balance by withdrawing and depositing money, not just by telling the banker how much you want to change it to. Include a constructor with parameters used to assign values to both attributes. Users should be able to withdraw money from an Account, deposit money into an Account, find monthly interest rate, and find monthy interest. Include methods for each of these actions. More details on them below. withdraw method This method simulates withdrawing money from the Account. It should not return a value and take the amount to withdraw as a parameter and reduce the balance by this amount. deposit method This method simulates depositing money into…Using python write a program that contains 1. a class named information that has the following hidden data attributes ( write appropriate accessor and mutator methods): name address age phone 2. using main() function create an instance of information that holds your information 3. following is the output after this program executes : my information: Name: Your name( first and last): address: 1111 my street. age: 24. phone Number: 555-555-1234 write code without commentsCreate a classstudent which includes parameters roll_no, name and address and consider as super class.Then create sub class test with parameters marl1, mark2, mark3 and mark4.
