Java - Check multiplicity between two class

Question

I would know It is possible in java language to write function. How to check the links between each class in java ? For example School |1 ----- 1..*| Student

Thanks for advance.

Do you mean measuring a has-a relation or what? This question is so unclear... — Eel Lee, Oct 11 '13 at 13:22
There are several UML tools that can read Java code and create an UML diagram for you, so yes it is possible. — Simon Forsberg, Oct 11 '13 at 14:40

One-to-many relationships in Java is typically implemented as a List property:

class School {
    private List <Student> students;
    ...

So to know how many students does your school have you call students.size().

I hope I understood your question correctly.
