Modify the Car class example and add the following: A default constructor that initializes strings to “N/A” and numbers to zero. An overloaded constructor that takes in initial values to set your fields (6 parameters). accel() method: a void method that takes a double variable as a parameter and increases the speed of the car by that amount. brake() method: a void method that sets the speed to zero. To test your class, you will need to instantiate at least two different Car objects in the main method in the CarDemo class. Each of your objects should use a different constructor. For the object that uses the default constructor, you will need to invoke the mutator methods to assign values to your fields. Invoke the displayFeatures() method for both objects and display the variables. Demonstrate the use of the accessor method getColor() by accessing the color of each car and printing it to the console. Use the method accel to increase the speed of the first car by 65 mph. Use…

Write an overload the constructor for this class that accepts actor’s name as a parameter Write accessor methods for each of the attributes. Write a method “winsAnOscar” that increases the number of awards by one and prints “The crowd applauds for <actor’s name>!” Be sure to use accessors where appropriate. Make sure your header is complete, with the appropriate level of visibility and any required keywords.

1. Create a properly encapsulated class named Person that has the following: A String instance variable called name. A constructor that takes a String parameter and sets the instance variable. A properly named getter for the instance variable. A correctly overrided equals method which returns true if the name instance variable of the parameter and the reference variable calling the method are equal. (Do not forget the null and class type checks!) Compile your Person class. 2. Create a properly encapsulated class named Employee that inherits from Person and has the following: ● ● ● A String instance variable called office (e.g. "LWH 2222"). A String instance variable called hourlywage (e.g. "$45.15"). A constructor that takes three Strings as parameters for name, office, and hourlyWage and sets the instance variables of both the parent class and the Employee class. An overridden toString method that returns the concatenation of name and hourlyWage instance variables (separated by a…
1. Design a new Triangle class that extends the abstract GeometricObject class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.
Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc.  Then create characteristics (breed, age, size, color) can form a data member for your object. Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.
Write a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbee
1. Create a class called Elevator that can be moved between floors in an N-storey building. Elevator uses a constructor to initialize the number of floors (N) in the building when the object is instantiated. Elevator also has a default constructor that creates a five- (5) storey building. The Elevator class has a termination condition that requires the elevator to be moved to the main (i.e., first) floor when the object is cleaned up. Write a finalize() method that satisfies this termination condition and verifies the condition by printing a message to the output, Elevator ending: elevator returned to the first floor. In main(), test at least five (5) possible scenarios that can occur when Elevator is used in a building with many floors (e.g., create, move from one floor to another, etc.). Hint: Termination occurs when the instance is set to null. You may wish to investigate “garbage collection” for this exercise.
Overriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.
Design a class named octopus that holds attributes for an octopus named weight and color. Include methods to set and get each of these attributes. Create the class diagram and write the class pseudocode that defines the class. Create a small program that declares two octopus objects and set the octopus's name weight and color attributes the program must also output each octopus's name weight and color after they are set. Please write out the pseudocode. I have a hard time with this.
