定义数组，存放5个学生的成绩【成绩值自己设定】，将成绩从大到小排序，获得成绩之和，平均成绩，最小成绩，最大成绩。Java

在Java中，我们可以定义一个名为`StudentScore`的对象数组来存储每个学生的成绩，并使用`Arrays.sort`函数对成绩进行降序排列。以下是详细的步骤：

首先，定义一个`StudentScore`类，包含姓名和成绩属性：

class StudentScore {
    String name;
    double score;

    // 构造函数、getters和setters省略
}

然后，创建并填充数组：

public class Main {
    public static void main(String[] args) {
        StudentScore[] students = new StudentScore[5];

        students[0] = new StudentScore("张三", 90.0);
        students[1] = new StudentScore("李四", 85.0);
        students[2] = new StudentScore("王五", 95.0);
        students[3] = new StudentScore("赵六", 75.0);
        students[4] = new StudentScore("孙七", 88.0);

        // 排序并计算成绩相关统计
        sortAndCalculate(students);
    }

    public static void sortAndCalculate(StudentScore[] scores) {
        Arrays.sort(scores, Comparator.comparingDouble(StudentScore::getScore).reversed());

        double totalScore = 0.0;
        double sumScores = 0.0;
        double minScore = Double.MAX_VALUE;
        double maxScore = Double.MIN_VALUE;

        for (StudentScore student : scores) {
            totalScore += student.score;
            sumScores += student.score;
            minScore = Math.min(minScore, student.score);
            maxScore = Math.max(maxScore, student.score);
        }

        double averageScore = totalScore / scores.length;
        System.out.println("Sorted Scores:");
        for (StudentScore student : scores) {
            System.out.println(student.name + ": " + student.score);
        }
        System.out.println("Total Score: " + totalScore);
        System.out.println("Average Score: " + averageScore);
        System.out.println("Minimum Score: " + minScore);
        System.out.println("Maximum Score: " + maxScore);
    }
}

这段代码首先对成绩数组按降序排序，然后分别累加总分，求和，以及找到最小和最大的成绩。最后计算平均分并打印所有统计结果。
