[thanks BEN!
I did started learning.but i wanted the idea from some one who can give me some clue which class i shall use.my idea is to start with.
public class ActiveUsers { private final Map map = new HashMap(); public synchronized void put(String sessionId, String userName) { map.put(sessionId, userName); } public synchronized void remove(String sessionId) { map.remove(sessionId); } public synchronized Map getMap() { return new HashMap(map); } }
