- variables are variables that have the same name as variables that have been declared in a superclass and are declared in a subclass, respectively.Variables having the same name as variables declared in a superclass are assumed to be the same as variables specified in a subclass.Design a class named CommunityMember and then create two subclasses named Student and Employee. Also create two subclasses of Employee for Faculty and Staff. A CommunityMember has a name, address, phone number, ande-mail address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as aconstant, e.g. status 1 for freshman, status 2 for sophomore, 3 for junior and 4 for senior. An Employee has an office, salary, and date Hired. For dateHired use class java.util.Date() to set the current date as dateHired. A faculty member has office Hours and a rank. A Staff member has a title either Senior or Junior. Override the toString method in each class to display the class name (i.e. CommunityMember, Student, Employee, Faculty, or Staff), the person’s name, and common data members, and specific data members
- 1. Create an interface OnlineQuiz with the following details: Member variables: totalMarks=10 Member Methods: · nQuestions(): An abstract method that calculates and return the number of questions. Defined in subclass. · display(): An abstract method that displays all details. Defined in a subclass. 2. Create a class Staff that inherits OnlineQuiz with the following details: Member variables: · staffD // id of the staff string type · staffName // Name of the staff string type · nMCQ // Number of MCQ type questions int type · nTF // Number of true/false type questions int type · nMatch // Number of match type questions int type Member Methods: · Define the parameterized constructor to set the member variables. · Define the method nQuestions(): which calculate and return the total number of questions. Total number of question= nMCQ + nTF +…Inheritance Create a base class called Shape with two final variables: PI and shapeType. PI should be set to 3.14159 and shapeType should be a String that indicates the type of shape. Create a subclass called Circle that extends Shape. Circle should have an instance variable called radius and a constructor that initializes radius. Override the toString() method to display the details of the circle, including its shape type, radius, and area. Create another subclass called Rectangle that extends Shape. Rectangle should have two instance variables called length and width, and a constructor that initializes length and width. Override the toString() method to display the details of the rectangle, including its shape type, length, width, and area. In the main method, create objects of Circle and Rectangle and call their toString() methods to demonstrate inheritance and the use of final variables.Inheritance – Create two abstract subclasses of AECar. Next create four additional subclasses. (Note: if you are having difficulty check out some online resources and see what categories of alternative energy cars exist.) Decide which properties should be pushed up into a super abstract class and which belong in the individual subclasses. You do not need to code every method – just place a stub placeholders
- JAVA please help Design a class named Sandwich with data fields for description and price. Include a constructor that requires arguments for both fields and a method to display the data (example value for description is chicken). Create a subclass named DeliverySandwich that inherits from Sandwich and has a delivery fee and a delivery address as additional fields. The description, price, and delivery address are required as arguments to the subclass constructor. The delivery fee should be set to $3 if the sandwich ordered costs more than $15; otherwise it should be set to $5. Write an application that instantiates at least two objects of each type and displays their state (data).True or False:Unlike other members of a superclass, constructors of a superclass are not inherited by its subclasses. This means that you must define a constructor for a class or use the default constructor added by the compiler.Variables with the same name as variables that have been declared in a superclass and variables that have been defined in a subclass are considered to be the same variable.
- What key word is used to define a subclass from a super class? Write a Java statement that defines the subclass CSEFaculty class from the superclass CSEEmployee class (which is already defined)Create a TeeShirt class for Lebo’s Tee Shirt Company. Attributes include an order number, size, color, and price. Create set methods for the order number, size, and color and get methods for all four attributes. The price is determined by the size: R122.99 for XXL or XXXL, and R109.99 for all other sizes. Create a subclass named CustomTee that descends from TeeShirt and includes an attribute to hold the slogan requested for the shirt, and include get and set methods this field. The display() method should me an abstract method. Write a test class named DemoTees.java that creates two objects of each class, and demonstrate that all the methods work correctly by communicating to the user to input the tee shirt size, color, and slogan, then display the tee shirt order number, size, color, slogan and price. Format your output to 2 decimal places. The user should be asked to repeat the process or not, (y) indicates yes they want to repeat the process an the process repeats and (n)…A variable having the same name as a variable that has been declared in a superclass and a subclass is considered the same variable.
