At the moment the <> combobox on the

getCategories. Add another
staticcollection field to the DAO class for storing the categories. Modify the
saveProductmethod so that it also extracts the category from the product being saved (using the getter method to get the category from the product) and store it in the new field. Return the new field in the
SimpleListModelobject to get the data into the category combobox on the
ProductEditordialog. It is the same process that you used to get the products into the product viewer dialog.
Add a new DAO test to your existing test class to test that your new method returns categories correctly.
Create the following two sequence diagrams using PlantUML.
Create a new folder in the root of your project named <>. Save your
puml files in this folder.
You can use VS Code in the lab, or your own version (assuming you have the PlantUML plugin installed) to create the diagrams. If you have not taken INFO201 then refer to lab 1 of INFO201 for instructions on installing and configuring VS Code and the PlantUML plugin.
If you don't have VS Code installed then you may prefer to use one of the following online editors and copy and paste between the online editor and the file in your project (via a different text editor):
Don't forget to complete all four domain classes. The complete domain model including the methods, and relationships is part of milestone 1.
There is bonus task that is relevant to this lab:
ProductViewerdialog in sorted order (by product ID) when using the collections based DAO. This task is about using sorted collections in the DAO class as described in lecture 5.
