Write a class named GasTank containing: • An instance variable named amount of type double, initialized to 0. • A method named addGas that accepts a parameter of type double. The value of the amount instance variable is increased by the value of the parameter. • A method named useGas that accepts a parameter of type double. The value of the amount instance variable is decreased by the value of the parameter. However, if the value of amount is decreased below 0, amount is set to 0. • A method named isEmpty that accepts no parameters. isEmpty returns a boolean value: true if the value of amount is less than 0.1, and false otherwise. • A method named getGasLevel that accepts no parameters. getGasLevel returns the value of the amount instance variable.

Object Oriented Programming in JAVA Define and use a class for the student record. The class should have instance variables for the quizzes, midterm, final, overall numeric score for the course, and final letter grade. The overall numeric score is a number in the range 0 to 100, which represents the weighted average of the student’s work. The class should have methods to compute the overall numeric grade and the final letter grade. These last methods should be void methods that set the appropriate instance variables. Your class should have a reasonable set of accessor and mutator methods, an equals method, and a toString method.
Write the definition of a class Player that has the following methods: • An __init__ method that initializes the following attribute variables: o An attribute variable named name , initialized to the empty string. o An attribute variable named score , initialized to the value 0. • A method named set_name that accepts one argument that is assigned to the attribute variable name . • A method named set_score that accepts one argument that is assigned to the attribute variable score . • A method named get_name that accepts no arguments, and returns the value of the attribute variable name . • A method named get_score that accepts no arguments, and returns the value of the attribute variable score .
Write a program named SalespersonDemo that instantiates objects using classes named Real EstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each objects data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salespersons full nameâ€”the first and last names separated by a space. Then perform the following Create two child classes of Salesperson: Real EstateSalesperson and Girl Scout. The Real EstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are initialized to 0), and a commission rate field required by the class constructor. The Girl Scout class includes a field to hold the number of boxes of cookies sold, which is initialized to 0. Include properties for every field. Create an interface named ISell able that contains two methods: SalesSpeech() and MakeSale(). In each Real EstateSalesperson and Girl Scout class, implement SalesSpeech() to display an appropriate one- or two-sentence sales speech that the objects of the class could use. In the Real Estatesalesperson class, implement the MakeSale() method to accept an integer dollar value for a house, add the value to the Real EstateSalespersons total value sold, and compute the total commission earned. In the Girl Scout class, implement the MakeSale() method to accept an integer representing the number of boxes of cookies sold and add it to the total field.

This is the question - Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum. The Rock class contains the following fields: sampleNumber - of type int description - A description of the type of rock (of type String) weight - The weight of the rock in grams (of type double) Include a constructor that accepts parameters for the sample number and weight. The Rock constructor sets the description value to "Unclassified". Include get methods for each field. Create three child classes named IgneousRock, SedimentaryRock, and MetamorphicRock. The constructors for these classes require parameters for the sample number and weight. Search the Internet for a brief description of each rock type and assign it to the description field using a method named setDescription inside of the constructor. This is the code I have, the program does not like at all what I have - import java.util.*; public class DemoRock { public static…

Python program for this project: Patient Charges Write a class named Patient that has attributes for the following data: First name, middle name, and last name Address, city, state, and ZIP code Phone number Name and phone number of emergency contact The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: Name of the procedure Date of the procedure Name of the practitioner who performed the procedure Charges for the procedure The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute. Next, write a program that creates an instance of the Patient class, initialized with sample data. Then,…
constructor that sets all instance variable to a given values. instanc variables: Full name( service(int), monthly salary (double) Method to print information of the employee. B: Create a class called Employee that includes five pieces of information as: yearly salary for them.
Design a class called Date that has integer data members to store month , day, and year. The class should have two constructors; a default constructor that accepts no parameters, and a three-parameter constructor that allows the date to be set by the programmer. If the user creates a Date object without passing any arguments, or if any of the values passed are invalid, the default values of 1, 1, 2001 (i.e., January 1, 2001) should be used. The class should have three (3) member functions to print the date in the following formats: 3/15/16 March 15, 2016 15 March 2016 Demonstrate the class by writing a program that uses it. Be sure your program only accepts reasonable values for month and day. The month should be between 1 and 12. The day should be between 1 and the number of days in the selected month. I expect to see all uses of the constructors that you made, including the error checking. I also expect to see all uses of the 3 output functions in your program. You are responsible…
