Direct association implemetation in java

Direct association implemetation in java

(OP)
Hi,

I would like to know how do you implement a direct association in java. Say i have two classes: Player and Ball related with direct association. How can I implement those two classes and their relationship in Java or php?

Do you know a link that gives examples of implementations for each kind of relationship?

Thanks

RE: Direct association implemetation in java

You can associate them in either direction, or both.  Add a Ball property to the Player object whose value is a reference to a Ball object.  Do the reverse also if the Ball needs to call functionality in the Player object, which seems a bit unlikely.

An unforeseen consequence of the information revolution has been the exponential propagation of human error.
