案例要求：
①从控制台接收3名学员的信息，每条信息存储到一个Student对象中，
②将多个Student对象存储到一个集合中
③将集合中学员信息存储到文件Student.txt中。
每名学员信息存储一行，多个属性值中间用空格隔开

public class T3 {
public static void main(String[] args) throws Exception {
    recive();
}

//接受学生信息并存储

public static void recive() throws Exception {
    ArrayList<Student> list = new ArrayList<>();
    Scanner sc = new Scanner(System.in);
    for (int i = 0; i < 3; i++) {
        System.out.println("请输入第"+(i+1)+"学生的姓名");
        String name = sc.next();
        System.out.println("请输入第"+(i+1)+"学生的年龄");
        int age = sc.nextInt();
        list.add(new Student(name,age));
    }
    FileWriter fw = new FileWriter("Student.txt");
    BufferedWriter bw = new BufferedWriter(fw) ;

    for (Student student : list) {
        String name = student.name;
        int age = student.age;
        bw.write(name+" "+age);
        bw.newLine();
        bw.flush();
    }
    bw.close();
}
}

//学生类
class Student{

String name;
int age;
public Student() {
}

public Student(String name, int age) {
    this.name = name;
    this.age = age;
}

@Override
public String toString() {
    return "Student{" +
            "name='" + name + '\'' +
            ", age=" + age  +
            '}';
}
