题目：录入学员信息并保存，当录入学员的编号为0时结束，展示出学员信息
//student类
public class Student {
public int id;
public String name;
public int age;
public Student() {
super();
}
public Student(int id, String name, int age) {
super();
this.id = id;
this.name = name;
this.age = age;
}
//text
public class Text {
public static void main(String[] args) {
System.out.println("*****录入学员信息，当录入学员的编号为0时结束*****");
Scanner input = new Scanner(System.in);
ArrayList<Student> arraylist = new ArrayList<Student>();
//输入学员信息
while(true){
Student student = new Student();
System.out.print("请输入学员学号：");
student.id = input.nextInt();
if(student.id==0){
System.out.println("结束录入！");
break;
}else{
System.out.print("请输入学员姓名：");
student.name = input.next();
System.out.print("请输入学员年龄：");
student.age = input.nextInt();
arraylist.add(student);
}
}
//输出学员信息
System.out.println("学员的信息如下：");
System.out.println("学号 姓名 年龄");
Iterator<Student> iterator = arraylist.iterator();
while(iterator.hasNext()){
Student a = iterator.next();
System.out.println(a.id+" "+a.name+" "+a.age);
}
}
运行结果：
