- Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…What are the benefits of having a destructor for a class?Default constructors are inherited from the base class, thereby eliminating the need for derived classes to define their own default constructors. O True O False
- Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. Core Class Components For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJavaIn order to extend a class, the new class should have access to all the data and inner workings of the parent class. True Falseemployee and production worker classes write an employee class that keeps data attributes for the following pieces of information: • employee name • employee number next, write a class named productionworker that is a subclass of the employee class. the productionworker class should keep data attributes for the following information: • shift number (an integer, such as 1, 2, or 3) • hourly pay rate the workday is divided into two shifts: day and night. the shift attribute will hold an integer value representing the shift that the employee works. the day shift is shift 1 and the night shift is shift 2. write the appropriate accessor and mutator methods for each class. once you have written the classes, write a program that creates an object of the productionworker class and prompts the user to enter data for each of the object’s data attributes. store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen. satak overfallow
- True or false: A class may have a constructor with no parameter list, and an overloaded constructor whose parameters all take default arguments.When a derived class method and a base class method have the same name, the derived class method is frequently referred to as the base class method.A constructor when overloaded, is selected by number, types and order of its parameters. can specify return types. cannot have the same name as the class. O cannot be overloaded.
- 1. Employee and ProductionWorker Classes Write an Employee class that keeps data attributes for the following pieces of information: Employee name Employee number Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: Shift number (an integer, such as 1, 2, or 3) Hourly pay rate The workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for each class. Once you have written the classes, write a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object’s data attributes. Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen. 2. ShiftSupervisor Class In a…T/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.In order to use the assignment operator on an instance of a class data type, it must be overloaded.
