Transcribed Image Text:There are common attributes and methods between kids and trainers. What is the best choice
for designing and writing the codes of these two classes? Explain your answer.
þraw a simple class diagram showing only relationships between the classes.
Implementation:
After analysing the given requirements, implement the required application:
• with Object Oriented Programming style
tellowing 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
If the user tries to do an operation that could violate the state of objects, the operation
should bejenered and the application should display an error message (e.g. adding a kid to
the same group 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 kids as follows: o It has one
collection to store the whole data (all groups of all sports) o It has static methods, one for
each operation happens frequently
g 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 groups of at least 3 sports and add them to the collection that stores the
whole data then add and remove some kids 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.
