同时按降序打印多个数组

Question

我正在尝试让我的代码按从高到低的顺序显示名称和分数（由用户提供）。我的代码还显示最高等级，最低等级和平均等级。

但我不知道如何按顺序显示名称和分数。

这是我的代码：

    <?php

include "conectarse.php";

//Obtener los datos de la pag web.
$usuario = $_POST['botonUser'];
$pass1 = $_POST['botonPass'];

//Procedo a conectarme a la Base de Datos
$link = conectarse($baseDatos);

$query_select = "SELECT * FROM usuarios WHERE usuario = '$usuario' AND pass = '$pass1';";

$registro = $link->query($query_select);

if($row = mysqli_fetch_array($registro))
    {    
    session_start();

    $_SESSION['nom'] = $row['nombre'];
    $_SESSION['apellido'] = $row['apellido'];
    $_SESSION['usuario'] = $row['usuario'];
    $_SESSION['tiempo'] = strftime("Hoy es %A y son las %H:%M");

    echo 'Si';

    }
    else {
        session_start();

        echo "No";
        $_SESSION['nom'] = "Anonimo";
    }

$link->close();

?>

代码完成后，它应该是这样的。我在括号中有所有内容：

import java.util.ArrayList;
import java.util.Scanner;

public class FinalGrades {
    public static void main (String[] args) {
        ArrayList<Integer> bestStudentPosition  = new ArrayList<Integer>();
        ArrayList<Integer> worstStudentPosition = new ArrayList<Integer>();
        Scanner input = new Scanner(System.in);
        System.out.print("How many students are in your class? ");
        int totalStudents = Integer.parseInt(input.nextLine());
        String[] names = new String[totalStudents];
        double[] scores = new double[totalStudents];
        double maxGrade = 0;
        double minGrade = 0;
        double avg = 0;
        double sum = 0;
        for (int i = 0; i < totalStudents; i++) {
            System.out.print("Name: ");
            names[i] = input.next();
            System.out.print("Score: ");
            scores[i] = input.nextDouble();
            sum += scores[i];
            if (i == 0) {
                minGrade = scores[0];
            }
            if (scores[i] > maxGrade) {
                bestStudentPosition.clear();
                maxGrade = scores[i];
                bestStudentPosition.add(new Integer(i));
            } else if (scores[i] == maxGrade) {
                bestStudentPosition.add(new Integer(i));
            }
            if (i > 0 && scores[i] < minGrade) {
                worstStudentPosition.clear();
                minGrade = scores[i];
                worstStudentPosition.add(new Integer(i));
            } else if (scores[i] == minGrade) {
                worstStudentPosition.add(new Integer(i));
            }

        }

        avg = sum / totalStudents;
        System.out.print("Highest score: ");
        for (Integer position : bestStudentPosition) {
            System.out.println(maxGrade + ", " + names[position]);
        }
        System.out.print("Lowest score: ");
        for (Integer position : worstStudentPosition) {
            System.out.println(minGrade + ", " + names[position]);
        }

        System.out.printf("Average: %3.2f", avg);

    }

}
