如何使用java来创建一个学生类？

Question

如题所述

Answer 1

首先，你需要创建一个学生类来表示学生的信息，例如：

public class Student {

private String name;

private int age;

private String gender;

private String grade;

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

this.name = name;

this.age = age;

this.gender = gender;

this.grade = grade;

}

// getters and setters

}

然后，你可以使用 ArrayList 集合来存储这些学生对象，例如：

import java.util.ArrayList;

public class Main {

public static void main(String[] args) {

ArrayList<Student> students = new ArrayList<>();

students.add(new Student("Alice", 18, "Female", "Freshman"));

students.add(new Student("Bob", 19, "Male", "Sophomore"));

students.add(new Student("Charlie", 20, "Male", "Junior"));

students.add(new Student("Diana", 21, "Female", "Senior"));

students.add(new Student("Eve", 22, "Female", "Senior"));

students.add(new Student("Frank", 23, "Male", "Senior"));

students.add(new Student("Gary", 24, "Male", "Senior"));

students.add(new Student("Hannah", 25, "Female", "Senior"));

students.add(new Student("Ivy", 26, "Female", "Senior"));

students.add(new Student("Jack", 27, "Male", "Senior"));

// loop through the students and print their information

for (Student student : students) {

System.out.println(student.getName() + ", " + student.getAge() + ", " + student.getGender() + ", " + student.getGrade());

}

}

}

这样，你就可以使用 ArrayList 集合来存储10个学生的信息了。你还可以使用 ArrayList 集合的方法来操作这些学生信息，例如增加、删除、查询等。
