Hi,

Suppose I have following classes:

class Person {
...

}

class Team {
    //how to have a member variable which holds an array of objects of Person?

...
}

Person person1= new Person("John Smith");
Person person2= new Person("Linda King");
Person person3= new Person("Ed Johnson");

//here is what I want:
Team BestTeam;
BestTeam = person1 + person2;
//now an object of class Team was created and this team has the two people

BestTeam = BestTeam + person3;
//now Ed Johnson joined the team

BestTeam = BestTeam - person3;
//now Ed Johnson left the team

Can we overload "+" and "-" to achieve the effect above? If not(which is
my feeling), how can we achieve something similar? If we use a method
(say,join(), left()), please give me full implementation of the method?
