Collection集合存储学生对象并遍历 案例

//创建集合对象
Collection c = new ArrayList();
Student s1 = new Student(“张三”, 20);
Student s2 = new Student(“李四”, 40);
Student s3 = new Student(“王五”, 50);

    c.add(s1);
    c.add(s2);
    c.add(s3);

    Iterator<Student> i = c.iterator();
    while (i.hasNext()) {
        Student n = i.next();
        System.out.println(n.getName() + "," + n.getAge());
    }
