There is only one more class we have to write up, and it's the store, the store divides into aisles,

into rows, and each row has many items.

So right there, we already know that we need to store items using a tuti array.

And we're going to call the two day right items and as always, if a class has fields, you need to

apply the big three steps, a constructor, a getter and a setter constructor.

Public shares the same name as the class receives no parameters.

Because in the beginning, her story is going to be empty and we're just going to set the field equal

to a new to the array of item objects with seven arrows and three columns.

Now we want to add a her.

That receives two parameters into row and column, and it's going to return an object of the item class.

At the request, the row and column.

Now we want to add a setter that receives three parameters.

Entero.

And Colin.

And the item we're going to use to update the story and it's going to update the element at the request

of the Roon column.

Equal to a new copy of the item object that was passed on.

All right, now, before adding the two string method, we're just going to set up some code and main.

First, remove what you have in main.

And copy the tutelary from the article that I left you.

Then create an object of the store class.

Store store is equal to a new object of the store class.

And we need to populate the store with every item from the tutera.

The outer loop counter I is going to index every row.

And the inner loop countered, Jay is going to index every element and I.

And then we can update the stories extorts, said Eitam.

With every item from Rowby and column J of the inventory to the array.

We've written a lot of code and it would be a good idea to test it before moving on, so we've launched

a debugger.

I as zero zero.

It updates the element at Index zero zero, Nimmi zero Jazz one, it updates the element at index zero

one.

OK, I'm pretty confident it's going to work.

Anyways, now we want to add the two string method.

As always, public string to string.

First, we set a string variable temp that equals an empty string.

Then we return it's.

Then I'm going to create a loop that runs through every item in the items array and as the outer loop

counter I indexes every row, the inner loop countered J is going to index every single element in a

row I.

Then I can grab every single element I and element, just grab the two string of that item and add it

to the string.

And then back in Maine, I'm going to grab the following print statements from the article.

And OK, we're looking good, riggi to separate each row into its own line because every row prints

on the same one.

So after the inner loop runs through an entire row, I'm going to add two lines, separators to temp.

And this is shaping up really well.

Back in the article, it tells us that this switch statement.

If you look at the output, each I'll name is printed before the inner loop prints an entire row of

data.

So that means you need to add a switch statement right before the inner loop.

And it works perfectly every time the outer loop runs at Prince, one of the strings, depending on

what the outer loop indexes.

And then the inner loop prince, an entire row of data.

This process repeats seven times, which results in seven aisles of product being printed, by all means,

feel free to add breakpoints and visualize the runtime.

It can be really satisfying.

And the last thing we want to do, which is purely for static reasons, is to add some stars at the

very end of the string.

So right after the nested loop runs to completion, we can append the closing stars.

And voila.
