s a simple program where we could identify the fields on the web page easily
using just the class attribute. There are others that are more complex, and the field
can be identified by alternative attributes. Some of these attributes are the id, the tag
name, etc. These have not been covered here, but you are likely to need them when
you deal with more complex web pages—google is probably one of the simplest by
design, since it is a universal search application where most of its complexity resides
on the server end.

A parent and two or more child classes are needed. Shape, Triangle, Rectangle are common examples where Shape is the parent and Triangle and Rectangle are the child classes. Create a project for the program, add the parent and childs classes to it. Use main to exemplify dynamic binding by creating an array or ArrayList of the parent class type and filling it with objects of the child class types. Loop through the array and display all the objects in it by calling their toString method. Then create a method whose parameter is the parent class type. Have main call the method sending it the child types. What the method does is up to you. Heavily document this program since this is not a prescribed assignment. I want to read your words. So I want you telling me what it does, how it does it, and how it has anything to do with dynamic binding. Then using screen capture software, take…arrow_forwardYou are asked to design a reservation framework. This could be expanded into an application to reserve anything that needs reserving, e.g., dental appointments, meetings, tickets for air planes, table of restaurants etc. 3.

- Hello! Need help with my Java Homework Please use Eclipse and Add a comments in each program to explain what your code is doing so I can understand it and learn. I really appreciate the help! Examine carefully the UML class diagram Attached: NOTE: Class Reptile was missing a toString() method. It has now been added. class Pet has an attribute of type java.util.Date. no specific dates are required for this attribute. compareTo(Dog) compares Dogs by weight. Create executable class TestPet as follows: create at least one Reptile pet and display it create an array of at least four Dog pets sort the array of Dogs by weight use a foreach loop to fully display all data for all dogs sorted by weight (see sample output) Sample Output Reptile name = Slinky, rock python, M Must be caged, crawls or slithers Not much sound, maybe a hiss, acquired Fri Feb 03 17:06:54 EST 2017 All dogs sorted by weight Dog name = Pedro, chihuahua, M Walks on a leash, weight 14 Barks or howls, acquired Fri…arrow_forwardThere are many different types of companies out there so trying to make one class that fits them all would be a challenge. We are going to take a look at modeling out a general company with the Company class and then customize that class with the OnlineCompany subclass. The basic structure is set up for both of these classes. Your task is to complete these classes as specified in the comments of each class. Once complete, use the CompanyTester class to create a Company and OnlineCompany object, then print each out using the toString(). public class CompanyTester{public static void main(String[] args){}} public class Company {private String name;private String streetAddress;private String city;private String state; // Set missing values to nullpublic Company(String name){} public Company(String name, String streetAddress, String city, String state){} public String getName(){} /*** Example output:* 123 Main St* Springfield, OH*/public String address(){} /*** Example output:*…arrow_forward
