    f         


        

Answer 1

If you want to remove inside a loop you should use an iterator and its remove method

public boolean removeStudent(String studentName)
{
    Iterator itS = students.iterator();
    while(itS.hasNext())
    {
        Student student = itS.next();
        if (studentName.equalsIgnoreCasee(student.getName()))
        {
            itS.remove();
            return true;
        }
    }
    return false;
}
