Question
Analysis: Q1: 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. Q2: Draw 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 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 If 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 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 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)
