Okay, we're ready to tackle the category functionality of the application.

What we'd like to do is add the ability to assign each GIF object to a category.

Then, we can create a list of these categories that will be displayed by

clicking on the categories link in the navigation menu.

Upon clicking on each category,

we'll see a page containing all the GIFs that are part of that category.

So, first things first.

We need a category model.

The category model will be a POJO that contains an integer ID field,

as well as a string name field.

We'll also need getters and setters for those, and a constructor too.

Go ahead, pause the video and give it a shot.

When you're ready to check your work against mine un-pause, and

I'll show you what I did.

All right, welcome back.

Let me show you how I coded the category model.

This model is a bit simpler than our GIF model since it contains only two fields.

First of all, I created a class named category and

put it in the model package to keep things nicely organized.

Then I added two fields, an int for the ID and a string for the name.

After that I had IntelliJ generate a constructor as well as getters and

setters for those two fields, and that's it.

Nothing too crazy happening here.

Now if your fields are named in a slightly different manner, don't worry.

Just take note of your differences and adjust your code accordingly.

In particular, differences in field names, more importantly your getters and

setters,will matter when you code the Thymeleaf templates.

In any case, make sure you're following the convention of starting your getter

names with get, or is for any boolean fields.

If you use IntelliJ to generate getters and setters, this will be done for you.
