Question

I’m working on a chat server, and I’m putting the Clients into a Hashtable.
This Hashtable is composed by <String name, Connection c>, where Connection has Socket and in-out flows.

I can send messages just looking for a nick in the Hashtable, but how can I send it to all the people?

Can I “Scout” (this was the unknown term) every Hashtable’s entry? (like an array, I want to “SCOUT” each entry, so I’ll do a loop and I’ll send the message to everyone).

Thanks in advance.

Answer 1

I can send messages just looking for a nick in the Hashtable, but how can I send it to all the people?

Then do the same for all nicknames in the hash table:

for (String name : yourTable.keySet())
    yourTable.get(name).send("your message");

or, alternatively:

for (Connection conn : yourTable.values())
    conn.send("your message");
