Exercice 1 :

These two first screenshots are the imputs of the application.

We can see that all the inputs have been stored and are appearing at the bottom of the screenshot.

After the next modification, all the contend had been kept in memory and we can still add others names.

Exercice 2:

The application had been loaded, all the informations had been displayed.

We can add a new part.

The part has been added to the list and has been displayed.

We can now modify the parts (here we added "test" at the end of the part).

The name had been changed and displayed correctly.

We can also delete a part.

The part had been deleted and can not be displayed anymore.
