'Something wrong' is not helpful. What is wrong? Quote a stack traces or
compiler errors.
However try this to begin with
// create new Volunteer
Volunteer volunteer = new Volunteer(String name, int telephone);
// Call add method with new volunteer
add(volunteer);
// add method
public boolean add(Volunteer volunteer)
{
Iterator it = volunteers.iterator();
while (it.hasNext())
{
Volunteers volunteers = (Volunteers) it.next();
if (volunteers.getName().equals(volunteer.getName())) //
does existing collection contain volunteer?
return false; // false indictating can't add
}
volunteers.add(volunteer); // no volunteer of this name, so add
return true; // return true indicating success
}
}
You'll need a getName() method in your Voluteer class which I imagine you
have or should have.
