    Default Class design

    Hi all

    i have a doubt in designing classes.
    currently i am dealing with an school management program.

    two of my main classes are Student, and Teacher, each contains attributes for each entity.

    my doubt is how i implement many-to-many relation in class?
    that is each student may have multiple number of teachers associate with.
    similarly each teacher have to assign may students.

    i am familiar in dealing this scenario in SOL using a third table.
    But how i model class to handle this in class itself....

    thanks in advance.....

    Keep it simple, Sally: can't each Teacher contain a List of Students, and can't each Student contain a List of Teachers?

    There is no "best one". Try it out. Does it work? Does it give you any problems?

    Define "best one", and we can try to go from there, but as a general rule: simpler is better.
