Java를 사용하여 간단한 학생 시험 점수 예측 시스템을 구현하는 방법은 무엇입니까?

public class Student {
    private String name;
    private int score;

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

    public String getName() {
        return name;
    }

    public int getScore() {
        return score;
    }
}

public class ScorePredictionSystem {
    private List<Student> students;

    public ScorePredictionSystem() {
        students = new ArrayList<>();
    }

    public void addStudent(Student student) {
        students.add(student);
    }

    public double calculateAverageScore() {
        int sum = 0;
        for (Student student : students) {
            sum += student.getScore();
        }
        return (double)sum / students.size();
    }
}

public double predictNextScore() {
    double averageScore = calculateAverageScore();
    return averageScore;
}

public class Main {
    public static void main(String[] args) {
        ScorePredictionSystem system = new ScorePredictionSystem();

        // 添加学生的历史考试成绩数据
        system.addStudent(new Student("张三", 80));
        system.addStudent(new Student("李四", 90));
        system.addStudent(new Student("王五", 70));

        // 预测下一次考试成绩
        double nextScore = system.predictNextScore();
        System.out.println("预测的下一次考试成绩为：" + nextScore);
    }
}
