JAVA键盘录入15个学生信息（学号，姓名，语文成绩，数学成绩，英语成绩）按照总分从高到低输出

好的，以下是JAVA代码实现：

import java.util.Scanner;
import java.util.Arrays;

public class Student {
    int id;
    String name;
    int chineseGrade;
    int mathGrade;
    int englishGrade;
    int totalGrade;

    public Student(int id, String name, int chineseGrade, int mathGrade, int englishGrade) {
        this.id = id;
        this.name = name;
        this.chineseGrade = chineseGrade;
        this.mathGrade = mathGrade;
        this.englishGrade = englishGrade;
        this.totalGrade = chineseGrade + mathGrade + englishGrade;
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Student[] students = new Student[15];

        // 录入学生信息
        for (int i = 0; i < students.length; i++) {
            System.out.println("请输入第" + (i+1) + "个学生的信息：");
            System.out.print("学号：");
            int id = scanner.nextInt();
            System.out.print("姓名：");
            String name = scanner.next();
            System.out.print("语文成绩：");
            int chineseGrade = scanner.nextInt();
            System.out.print("数学成绩：");
            int mathGrade = scanner.nextInt();
            System.out.print("英语成绩：");
            int englishGrade = scanner.nextInt();
            students[i] = new Student(id, name, chineseGrade, mathGrade, englishGrade);
        }

        // 按总分从高到低排序
        Arrays.sort(students, (a, b) -> b.totalGrade - a.totalGrade);

        // 输出学生信息
        System.out.println("按总分从高到低排序的学生信息如下：");
        for (int i = 0; i < students.length; i++) {
            System.out.println("学号：" + students[i].id +
                               " 姓名：" + students[i].name +
                               " 语文成绩：" + students[i].chineseGrade +
                               " 数学成绩：" + students[i].mathGrade +
                               " 英语成绩：" + students[i].englishGrade +
                               " 总分：" + students[i].totalGrade);
        }
    }
}

运行代码，会依次让你输入15个学生的学号、姓名、语文成绩、数学成绩和英语成绩，然后按照总分从高到低输出学生信息。
