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.
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…

- Object-Oriented Programming Create a Java program that has the following: Inheritance - Create a superclass and one or more subclasses that inherit properties and methods from the superclass. Polymorphism - Show polymorphism by using method overriding and method overloading. Provide an example of runtime polymorphism by creating objects of the subclasses and calling overridden methods. Encapsulation - Demonstrate the concept of encapsulation by applying access modifiers (private, protected, public) appropriately in your program. Abstraction - Utilize abstract classes and methods in your program to illustrate abstraction.

Your program must include a class Employee with the following requirements: Class attributes: name: the name of the employee position: the position of the employee start_salary: the starting salary of the employee annual_rate: the annual merit rate on the salary contract_years: the number of years of salary Class method: get_cumulative_salary(): calculates and returns the cumulative salary of an employee based on the number of contract years. Round the cumulative salary to two digits after the decimal point. Example: If start_salary = 100000, annual_rate = 5% and contract_years = 3: Then the cumulative salary should be : 100000 + 105000 + 110250 = 315250 Outside of the class Employee, the program should have two functions: Function name Function description Function input(s) Function output(s) / return…arrow_forward
