JAVA Create a Java project to implement a simple Name class. This class will have the following class variable: First Name, Middle Name, Last Name, and Full Name Create the accessor/getter and mutator/setter methods. In addition to these methods, create a toString() method, which overrides the object class toString() method. This override method prints the current value of any of this class object. Create a main() method to test your project.
Here is a sample run of the tester program: Make sure your program follows the Java Coding Guidelines. Consider the following class: /** * A store superclass with a Name and Sales Tax Rate */ public class Store { public final double SALES_TAX_RATE = 0.06; private String name; /** * Constructor to create a new store * @param newName */ public Store(String newName) { name = newName; } ...

Chapter 5 Assignment Read directions: In JAVA design and implement a class called Dog that contains instance data that represents the dog's name and dog's age. Define the Dog constructor to accept and initialize instance data. Include getter and setter methods for the name and age. Include a method to compute and return the age of the dog in "person years" (seven times age of dog. Include a toString method that returns a one-time description of the dog (example below)....
In this assignment, you will implement Address and Residence classes. Create a new java project. Part A Implementation details of Address class: Add and implement a class named Address according to specifications in the UML class diagram. Data fields: street, city, province and zipCode. Constructors: A no-arg constructor that creates a default Address. A constructor that creates an address with the specified street, city, state, and zipCode Getters and setters for all the class fields. toString() to print out all...
Java file Name Dog Classes and Methods Create a constructor that incorporates the type, breed, and name variables (do not include topTrick). Note: The type refers to what the breed typically does; for example, a corgi would be a “cattle herding dog.” A Shiba Inu would be a “hunting dog.” Create the setTopTrick() mutator method Dog is parent class Corgi and Driver are subclasses Complete the Corgi class: Using the UML Class diagram, declare the instance variables. Create the two...
Java Create four classes: 1. An Animal class that acts as a superclass for Dog and Bird 2. A Bird class that is a descendant of Animal 3. A Dog class that is a descendant of Animal 4. A “driver” class named driver that instantiates an Animal, a Dog, and a Bird object. The Animal class has: · one instance variable, a private String variable named name · a single constructor that takes one argument, a String, used to set...

Implement an abstract class named Person and two subclasses named Student and Staff in Java. A person has a name, address, phone number and e-mail address. A student has a credit hour status (freshman, sophomore, junior, or senior). Define the possible status values using an enum. Staff has an office, salaray, and date-hired. Implement the above classes in Java. Provide Constructors for classes to initialize private variables. Getters and setters should only be provided if needed. Override the toString() method...
In Java Code Needed is Below the Question Using Program 3: Encapsulating Dogs, modify this program to create a database of dogs of your own. You will also include File I/O with this program. You will create 3 classes for this assignment. The first class: Create a Class representing the information that is associated with one item (one dog) of your database. Name this class Dog. Using Lab 3, this will include the information in regard to one dog. The...
