The assignment contains two $.$java files. The Artwork.java file is the class file for Artwork

objects. Do NOT change the Artwork class.

The second file, Stack.java, is incomplete. This file contains the main method and the

skeleton of the lab. The methods are the following:

public void push$($Artwork artwork$)$

$//$This method takes an $`$Artwork$`$ object as a parameter and

adds it to the top of the stack. It essentially "pushes" the

artwork onto the stack, making it the newest element.

public Artwork pop$()$

$//$This method removes and returns the topmost $`$Artwork$`$

object from the stack. It "pops" the artwork off the stack,

effectively removing it from the collection.

public Artwork peek$()$

$//$This method retrieves, but does not remove, the top

$`$Artwork$`$ object from the stack. It allows you to peek at the

topmost artwork without removing it from the stack.

public void sortAscendingByyear$()$

$//$This method sorts the artworks in the stack in ascending

order based on their year attribute. It rearranges the

artworks so that the oldest artworks come first and the

newest ones come last.

public void sortAscendingByName$()$

$//$Like the previous method, this one sorts the artworks in

ascending order, but based on the artist's name. It rearranges

the artworks alphabetically by the artist's name.

public void display$()$

$//$This method simply displays all the elements of the stack.

It typically prints out each artwork's details, such as the

artist's name, title, medium, year, and value, starting from

the top of the stack and moving downwards.

Requirements: Your task is to complete Stack.java as instructed in the comments to

produce the necessary output. On the way, you must follow the following requirements.

$1.$ You must NOT change the main method.

$2.$ Do NOT change any of the method headers provided in Stack.java nor the any part

of methods.

$3.$ Feel free to write as many new methods, class variables as you need in Stack.java.

$4.$ The data file will contain more information when grading.

Sample output: Use this to format the print statements.

Initialize a stack:

Is the stack empty? true

$-----------------------------$

Input some elements on the stack:

Artwork "Mona Lisa" by Da Vinci pushed onto the stack

Artwork "Starry Night" by Van Gogh pushed onto the stack

Artwork "Guernica" by Picasso pushed onto the stack

Artwork "David" by Michelangelo pushed onto the stack

Artwork "The Night Watch" by Rembrandt pushed onto the stack

Stack elements:

Artist: Rembrandt, Title: The Night Watch, Medium: Oil, Year: $1642,$ Value: $1500000\mathrm{.}0$

Artist: Michelangelo, Title: David, Medium: Marble, Year: $1504,$ Value: $180000\mathrm{.}0$

Artist: Picasso, Title: Guernica, Medium: Oil, Year: $1937,$ Value: $200000\mathrm{.}0$

Artist: Van Gogh, Title: Starry Night, Medium: Oil, Year: $1889,$ Value: $120000\mathrm{.}0$

Artist: Da Vinci, Title: Mona Lisa, Medium: Oil, Year: $1503,$ Value: $100000\mathrm{.}0$

The top object in the stack is: Artwork$\{$artistName$=$'Rembrandt', title$=$'The Night Watch',

medium$=$'Oil', year$=1642,$ value$=1500000\mathrm{.}0\}$
