使用Iterator的方式也可以顺利删除和遍历 

eg:public voiditeratorRemove() {  

        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);  

}
