java用类和对象完成编写一个程序用来统计十个同学的最高分，最低分和平均分。

在Java中，我们可以创建一个`Student`类来表示每个学生，包含他们的分数属性。然后，我们可以创建一个`ScoreStatistics`类来处理计算最高分、最低分和平均分的功能。这里是一个简单的例子：

// Student 类，代表一个学生及其分数
class Student {
    private String name;
    private int score;

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

    // 获取分数的方法
    public int getScore() {
        return score;
    }

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

// ScoreStatistics 类，用于统计最高分、最低分和平均分
class ScoreStatistics {
    private List<Student> students;

    public ScoreStatistics(List<Student> students) {
        this.students = students;
    }

    public void calculateScores() {
        if (students.isEmpty()) {
            System.out.println("No students to calculate scores.");
            return;
        }

        int highestScore = Collections.max(students.stream().mapToInt(Student::getScore).boxed());
        int lowestScore = Collections.min(students.stream().mapToInt(Student::getScore).boxed());

        double sum = students.stream().mapToDouble(Student::getScore).sum();
        double averageScore = sum / students.size();

        System.out.println("Highest score: " + highestScore);
        System.out.println("Lowest score: " + lowestScore);
        System.out.println("Average score: " + averageScore);
    }
}

public class Main {
    public static void main(String[] args) {
        List<Student> students = new ArrayList<>();
        students.add(new Student("Alice", 95));
        students.add(new Student("Bob", 88));
        // ... 其他八个同学的添加类似

        ScoreStatistics stats = new ScoreStatistics(students);
        stats.calculateScores();
    }
}
