Implementation: After analysing the given requirements, implement the required application: • with Object Oriented Programming style • following the rules of good programming style (e.g. adding comments, etc.) using only the material covered in M251 (and its prerequisites) Hints: • For each class, it is required to implement constructors, setters, getters, toString() method, and any other necessary method • f the user tries to do an operation that could violate the state of objects, the operation should be ignored and the application should display an error message (e.g. adding a worker to the same workshop twice, etc.) • Checking equality of any 2 objects should be done via the equals() method • There is a class that will do the main job of keep tracking of the workshops as follows: o It has one collection to store the whole data (all workshops of all product lines) o t has static methods, one for each operation happens frequently o For each adding or removing operation, a message should be displayed to the user to explain the status of the operation (i.e. if it was successful or not) Testing: After implementing the required classes, design and implement a testing class to test them as follows: Create at least 7 workshops for at least 3 product lines and add them to the collection that stores the whole data then add and remove some workers from them. • Try to violate the state of the objects and show that your code prevents all violations. • Show that the other operations that happen frequently are working fine. • At the end, the whole data should be saved into a text file and this file should be saved automatically inside the folder contains your Java project.
