使用java完成5个分数：8.0,9.0,9.0,9.5,9.0。相加得：44.5，除以5乘以3(7个裁判情况下的打分规则）得：26.7. Difficulty 表示难度分，这里是3.4，用26.7x3.4=90.78。请在测试程序中，完成对该跳水选手打分的计算。

在Java中，你可以通过创建一个类来表示分数，然后使用ArrayList来存储这些分数，并进行相应的计算。首先，我们创建一个`Score`类，包含分数、总分、平均分以及难度分属性：

public class Score {
    private double[] scores;
    private int totalScorers;
    private double difficulty;

    public Score(double[] scores, int totalScorers, double difficulty) {
        this.scores = scores;
        this.totalScorers = totalScorers;
        this.difficulty = difficulty;
    }

    // 添加获取和设置方法，如getScores(), getTotalScorers(), setDifficulty()

    public double calculateAverage() {
        if (scores == null || scores.length == 0) {
            return 0;
        }
        double sum = Arrays.stream(scores).sum();
        return sum / totalScorers;
    }

    public double calculateDifficultyAdjustedScore() {
        return calculateAverage() * difficulty;
    }
}

接下来，我们可以创建并初始化`Score`实例，然后进行计算：

public static void main(String[] args) {
    double[] scores = {8.0, 9.0, 9.0, 9.5, 9.0};
    int totalScorers = 5;
    double difficulty = 3.4;

    Score divingScore = new Score(scores, totalScorers, difficulty);
    
    double averageScore = divingScore.calculateAverage();
    System.out.println("平均得分: " + averageScore);

    double adjustedScore = divingScore.calculateDifficultyAdjustedScore();
    System.out.println("调整后的得分（难度分*平均分）: " + adjustedScore);
}

当运行这个程序时，它会按照给定的条件计算出跳水选手的得分。
