使用Iterator的方式也可以顺利删除和遍历 
eg:
public void iteratorRemove() {  
        List<Student> students = this.getStudents();  
        System.out.println(students);  
        Iterator<Student> stuIter = students.iterator();  
        while (stuIter.hasNext()) {  
            Student student = stuIter.next();  
            if (student.getId() % 2 == 0)  
                stuIter.remove();  
        }  
        System.out.println(students);  
}
