蓝桥杯算法训练VIP-学生成绩-题解（Java代码）

解题思路:

注意事项:

参考代码:

import java.util.Arrays;

import java.util.Comparator;

import java.util.Scanner;

public class Main {

static class student{

String name="";

String sex;

int age;

int cj;

public String toString() {

String s=this.name+" "+this.sex+" "+this.age+" "+this.cj;

return s;

}

}

public static void main(String[] args) {

Scanner scanner=new Scanner(System.in);

int n=scanner.nextInt();

student[] stu=new student[n];

for(int i=0;i<n;i++) {

stu[i]=new student();

stu[i].name=scanner.next();

stu[i].sex=scanner.next();

stu[i].age=scanner.nextInt();

stu[i].cj=scanner.nextInt();

}

Comparator<student> cj=new Comparator<student>() {

public int compare(student o1, student o2) {

// TODO Auto-generated method stub

if(o1.cj>=o2.cj)

return 1;

return -1;

}

};

Arrays.sort(stu, cj);

for(student s:stu)

System.out.println(s.toString());

}

}
