3. Concurrent Map import java.util.Map;  import java.util.concurrent.ConcurrentHashMap; Map users = new ConcurrentHashMap(); users.put("admin", new AdminUser("admin", "acc355")); users.put("fred", new ClientUser("fred", "password"));

4. Distributed Map import java.util.Map; import com.hazelcast.core.Hazelcast; Map users = Hazelcast.getMap("users"); users.put("admin", new AdminUser("admin", "acc355")); users.put("fred", new ClientUser("fred", "password"));

5. Distributed Lock import java.util.concurrent.locks.Lock; import com.hazelcast.core.Hazelcast; Lock lock = Hazelcast.getLock(currentUser); lock.lock(); try {    currentUser.setDisplayName("...");     currentUser.save(); } finally {    lock.unlock(); }

6. Executor Framework public class HelperTask implements Callable<String> {     public String call() {         // Do things         return someString;    }} ExecutorService e = Hazelcast.getExecutorService(); Future<String> task = e.submit(new HelperTask()); String result = task.get();
