Create a program using classes that does the following in the zyLabs developer below. For this lab, you will be working with two different class files. To switch files, look for where it says "Current File" at the top of the developer window. Click the current file name, then select the file you need.(1) Create two files to submit: ItemToPurchase.java - Class definition ShoppingCartPrinter.java - Contains main() method Build the ItemToPurchase class with the following specifications: Private fields String itemName - Initialized in default constructor to "none" int itemPrice - Initialized in default constructor to 0 int itemQuantity - Initialized in default constructor to 0 Default constructor Public member methods (mutators & accessors) setName() & getName() setPrice() & getPrice() setQuantity() & getQuantity() (2) In main(), prompt the user for two items and create two objects of the ItemToPurchase class.

Java Code. Create a Driver class to use your Farm and Animal classes and create instances of them. In the main method do the following: Create a Farm of size 10 Create 5 Animal Objects with the details specified in the table below Add the 5 Animal objects to the Farm Call the printDetails method from the Farm to print all the Farm and Animal details.
Create a new Python file in your project named FullName.py. In this module, create a class named FullName. When creating a FullName object, the client will pass a string for first name and a string for last name, which the constructor will assign to two attributes. Your class should have the following methods: __init__, __str__, and __gt__. __gt__ will compare two FullName objects using the following logic: If person A’s last name comes after person B’s last name alphabetically, person A is “greater than” person B. If their last names are equal, check their first names to see which is greater. Hint: The > and < operators are already overloaded for string objects, so your __gt__ method should be relatively simple. In your main.py file, demonstrate creating a few FullName objects and calling these methods on them.
Create an application named RecoveringDemo that declares objects of three types: Patient, Upholsterer, and FootballPlayer. Create an interface named IRecoverable that contains a single method named Recover(). Create the classes named Patient, Upholsterer, and FootballPlayer so that each implements IRecoverable. Create each class’s Recover() method to display an appropriate message. For example: The Patient’s Recover() method should display I am getting better. The Upholsterer's Recover() method should display I have new material for the couch. The FootballPlayer's Recover() method should display I picked up the ball after a fumble.

Create a simple chat application using Java programming to allow two clients to communicate with one another by sending a message to the server and having it transfer the message. The following needs to be implemented: Two classes with one named server and the other named client. Server can allow the clients to create their own nicknames before entering the chatroom. Add a ".exit" command to allow the users to disconnect after they are done chatting. In order to understand exactly what the program is doing, please provide both comments and screenshots for the codes including the input/output. If there are similar questions that have been asked before, please do not copy the same answers. Take your time creating the application. Just have it successfully run in the Java software you are using.
