- Create a class named CollegeCourse that includes data fields that hold the department (for example, ENG), the course number (for example, 101), the credits (for example, 3), and the fee for the course (for example, $360). All of the fields are required as arguments to the constructor, except for the fee, which is calculated at $120 per credit hour. Include a display() method that displays the course data. Create a subclass named LabCourse that adds $50 to the course fee. Override the parent class display() method to indicate that the course is a lab course and to display all the data. Write an application named UseCourse that prompts the user for course information. If the user enters a class in any of the following departments, create a LabCourse: BIO, CHM, CIS, or PHY. If the user enters any other department, create a CollegeCourse that does not include the lab fee. Then display the course data. Save the files as CollegeCourse.java, LabCourse.java, and UseCourse.java.Create a class called Book to represent a book. A Book should include four pieces of information as private instance variables‐a book name, an ISBN number, an author name and a publisher. Provide public get methods and set methods for each instance variable. Inaddition, provide a method named DisplayBookInfo that display the description of the book (the description should include all the information about the book like book name, ISBN number author name and publisher.

Private instance variable to store the experience of developer, number of applicationspublished, number of GitHub repositories. Parameterized constructor that sets all the instance variable. Setter and getter methods to set and get the instance variable values. A public method named calulateSalary() that returns the expected salary of the employee Salary of the developer is determined by: (experience of developer + number ofapplications published + number of GitHub repositories) * 500 $.If expected salary is less than 1000$ then assign the status to employee as “Rookie developer” and if the expected salary comes out to be greater then 1000$ then assign the status to the developer as “pro developer”. Create a method name displayInfo that will display all the information about thedeveloper along with its expected salary and status.
- Create a class called Employee that includes three instance variables—afirst name (type String), a last name (type String) and a monthly salary (double). Provide aconstructor that initializes the three instance variables. Provide a set and a get method for eachinstance variable. If the monthly salary is not positive, do not set its value. Write a test applicationnamed EmployeeTest that demonstrates class Employee’s capabilities. Create two Employeeobjects and display each object’s yearly salary. Then give each Employee a 10% raise and displayeach Employee’s yearly salary again.Create a class named Person that holds the following fields: two String objects for the person’s first and last name and a LocalDate object for the person’s birthdate.
