定义一个Student数组，其中保存学生的基本信息，包括姓名、学号、性别；分别保存三门课程的成绩。试编程对这三门课程的成绩降序排序，输出排序后的结果java

以下是 Java 代码实现：

import java.util.Arrays;
import java.util.Comparator;

class Student {
    String name;
    int id;
    String gender;
    int score1;
    int score2;
    int score3;
    
    public Student(String name, int id, String gender, int score1, int score2, int score3) {
        this.name = name;
        this.id = id;
        this.gender = gender;
        this.score1 = score1;
        this.score2 = score2;
        this.score3 = score3;
    }
    
    public String toString() {
        return name + "\t" + id + "\t" + gender + "\t" + score1 + "\t" + score2 + "\t" + score3;
    }
}

public class Main {
    public static void main(String[] args) {
        Student[] students = {
            new Student("张三", 1001, "男", 90, 80, 70),
            new Student("李四", 1002, "女", 80, 70, 60),
            new Student("王五", 1003, "男", 70, 60, 50),
            new Student("赵六", 1004, "女", 60, 50, 40)
        };
        
        Arrays.sort(students, new Comparator<Student>() {
            public int compare(Student s1, Student s2) {
                int totalScore1 = s1.score1 + s1.score2 + s1.score3;
                int totalScore2 = s2.score1 + s2.score2 + s2.score3;
                return totalScore2 - totalScore1;
            }
        });
        
        System.out.println("姓名\t学号\t性别\t成绩1\t成绩2\t成绩3");
        for (Student student : students) {
            System.out.println(student);
        }
    }
}

输出结果：

姓名    学号    性别    成绩1   成绩2   成绩3
张三    1001    男      90     80     70
李四    1002    女      80     70     60
王五    1003    男      70     60     50
赵六    1004    女      60     50     40
