//创建List集合对象，把学生添加到集合里
List s = new ArrayList();
Student student1 = new Student(“张三”,10);
Student student2 = new Student(“李四”,20);
Student student3 = new Student(“王麻子”,10);
s.add(student1);
s.add(student2);
s.add(student3);
//遍历循环 For循环模式
for (int i = 0; i < s.size(); i++) {
Student ss = s.get(i);
System.out.println(ss.getName()+","+ss.getAge());
}
System.out.println("---------------------------------");

    //采用迭代器方式遍历集合
    Iterator<Student>it =s.iterator();
    while (it.hasNext()){
        Student n = it.next();
        System.out.println(n.getName()+n.getAge());
    }
