HashMap & ArrayList collections

[Iain Linton]

I have:

private HashMap allTrips = new HashMap();
private ArrayList allMembers = new ArrayList();

I have a Class Member

my question is:

how do I get a member to join a trip (both the Member and Trip should be paremeters)

Do I have to convert the HashMap into a collection and iterate over it to get the trip code, also iterate over the ArrayList to get the member then join the on the trip.

The question is how?

All help would be greatly appreciated

I think you need to give us more information about what it means for a Member to "join" a Trip. Also, what exactly is in the HashMap (what are the key/value pairs)? And what is a "trip code"?

Or better yet, what have you tried, and what went wrong?

What do you have in your List and what do you have in your Map.

You will have to use an iterator to iterate through either.
