如何使用 Java 设计一个简单的成绩计算程序

// 创建学生类
class Student {
    private String name;
    private double score;
    public Student(String name, double score) {
        this.name = name;
        this.score = score;
    }
    public double getScore() {
        return score;
    }
}
// 创建成绩计算程序
import java.util.ArrayList;
import java.util.List;
public class ScoreCalculator {
    private List<Student> students;
    public ScoreCalculator() {
        students = new ArrayList<>();
    }
    public void addStudent(String name, double score) {
        Student student = new Student(name, score);
        students.add(student);
    }
    public double calculateAverage() {
        double sum = 0;
        for (Student student : students) {
            sum += student.getScore();
        }
        return sum / students.size();
    }
    public double findMax() {
        double max = Double.MIN_VALUE;
        for (Student student : students) {
            if (student.getScore() > max) {
                max = student.getScore();
            }
        }
        return max;
    }
    public double findMin() {
        double min = Double.MAX_VALUE;
        for (Student student : students) {
            if (student.getScore() < min) {
                min = student.getScore();
            }
        }
        return min;
    }
}
// 创建交互界面
import java.util.Scanner;
public class Main {
    public static void main(String[] args) {
        ScoreCalculator calculator = new ScoreCalculator();
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入学生姓名：");
        String name = scanner.next();
        System.out.print("请输入学生成绩：");
        double score = scanner.nextDouble();
        calculator.addStudent(name, score);
        System.out.println("平均分：" + calculator.calculateAverage());
        System.out.println("最高分：" + calculator.findMax());
        System.out.println("最低分：" + calculator.findMin());
    }
}
