Java-
- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.
Step by step
Solved in 2 steps
- Java - Write one or two sentences to describe the primary advantage of implementing an extended class. Your answer should use the word "inherited" at least once.Write a class in Java , named Patient that has fields 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 should have a constructor, accessor, and mutator that accept an argument for each field.Class student inherits from superclass Person. Which assignment is legal? a) Student s = new Person(); b) Person p = new Student(); c) Student s = new Student(); d) Person p = new Person();
- Create an interface Wheel with methods setWheels (int c) and getWheels () and a class Vehicle with abstract methods getColor () and getBrand (). Now, create a concrete class Taxi with additional method setDriver (String name) that inherits both Wheel and Vehicle. (Note: Concrete classes don’t have any abstract method)Hand-write two Java classes, Car and Truck. They are bothsubclasses of Vehicle.a. A car has an additional instance variable, number of doors.b. A truck has an additional instance variable, number of axlesc. Write a constructor that requires input for the instance variables of each class(including registration number and owner name).d. Write getters and setters for all instance variables for both classes.Please write a Java program with at least two classes. Use a circle to represent it! The class should have at least one non-static setter method and one non-static getter. Implement at least one method test that invokes the setter method and the corresponding getter method so that the value out == the value in!
- Java- Suppose you write a new constructor for an extended class. Describe two different ways that the superclass's instance variables could be initialized within the constructor for the extended class.Hand-write a complete Java class that can be usedto create a Car object as described below.a. A Vehicle has-a:i. Registration numberii. Owner nameiii. Priceiv. Year manufacturedb. Add all instance variablesc. The class must have getters and setters for all instance variablesd. The class must have two constructors, a no-args and a constructor that receivesinput parameters for each instance variable.Java program Make a class Employee with a name and salary. Make a class Manager inherit from Employee. Add an instance variable, named department, of type String. Supply a method toString that prints the manager’s name, department, and salary. Make a class Executive inherit from Manager. Supply appropriate toString methods for all classes. Supply a test program that tests these classes and methods.
- Write in Java Given main() and a base Book class, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a printInfo() method that overrides the Book class' printInfo() method by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes.Using JAVA write a code to: Implement a class Person with a name and a year of birth. Add a class Student that inherits from Person and has a major. Add a class Instructor that inherits from Person and has a salary. For each class, write the needed constructors, getters, setters, and a toString method that stringifies the instance variables in a readable format. Supply a test program that instantiates an instance of each class and exercises each method defined for the class.*using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…
