.给出存储班级三十名学生基本信息的Java代码，基本信息的具体赋值由考生自拟？

下面是一个存储班级三十名学生基本信息的 Java 代码示例：

import java.util.ArrayList

public class Student {

private String name

private int age

private String gender

public Student(String name, int age, String gender) {

this.name = name

this.age = age

this.gender = gender

}

public String getName() {

return name

}

public int getAge() {

return age

}

public String getGender() {

return gender

}

}

public class Classroom {

private ArrayList<Student>students

public Classroom() {

this.students = new ArrayList<Student>()

}

public void addStudent(Student student) {

students.add(student)

}

public ArrayList<Student>getStudents() {

return students

}

}

public class Main {

public static void main(String[] args) {

Classroom classroom = new Classroom()

// 添加 30 名学生的基本信息

classroom.addStudent(new Student("Tom", 18, "Male"))

classroom.addStudent(new Student("Alice", 19, "Female"))

// ...

// 此处省略 28 名学生的信息

// 获取所有学生的信息

ArrayList<Student>students = classroom.getStudents()

for (Student student : students) {

System.out.println("Name: " + student.getName())

System.out.println("Age: " + student.getAge())

System.out.println("Gender: " + student.getGender())

}

}

}

该代码定义了两个类：Student 类表示一个学生，包含了学生的姓名、年龄和性别等信息；Classroom 类表示一个班级，包含了一个学生的列表，并提供了添加学生和获取学生列表的方法。

在 Main 类的 main 方法中，我们首先实例化一个 Classroom 对象，然后依次添加 30 名学生的信息。最后，我们调用 getStudents 方法获取所

正规的写法，创建Student类，要有构造方法，重写toString方法，这个可以改为你需要的格式

public class Student {

private String number

private String name

private char sex

private double[] score=new double[3]

private double ave

private double sum

public String getNumber() {

return number

}

public void setNumber(String number) {

this.number = number

}

public String getName() {

return name

}

public void setName(String name) {

this.name = name

}

public char getSex() {

return sex

}

public void setSex(char sex) {

this.sex = sex

}

public double[] getScore() {

return score

}

public void setScore(double[] score) {

this.score = score

}

public double getAve() {

return ave

}

public void setAve(double ave) {

this.ave = ave

}

public double getSum() {

return sum

}

public void setSum(double sum) {

this.sum = sum

}

@Override

public String toString() {

return "Student [number=" + number + ", name=" + name + ", sex=" + sex

+ ", score=" + Arrays.toString(score) + ", ave=" + ave

+ ", sum=" + sum + "]"

}

public Student() {

}

public Student(String number, String name, char sex, double[] score,

double ave, double sum) {

super()

this.number = number

this.name = name

this.sex = sex

this.score = score

this.ave = ave

this.sum = sum

}

然后你另外写一个类，里面有input 和 output方法来 *** 作你的这个学生类。
