Q1: Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. A data field radius with a get method. A data field radius with a get method. A no-arg constructor that creates a default circle with (0,0) for (x, y) and 1 for radius. A constructor that creates a circle with the specified x, y, and radius. A method getAreal) that returns the area of the circle. A method getPerimeter() that returns the perimeter of the circle. A method contains(double x, double y) that returns true if the specified point (x,y) is inside this circle(a) Amethod contains (Circle2D circle) that returns true if the specified circle is inside this circle(b) A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle(c) (a) (b) (c) Q2: 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 email 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 Date class 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. Write a test class that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods
