Question

在项目中，我看到一个人误创建的多个区域存储桶，该存储桶用于数据管道。应该是区域性的桶。建议将其更改为区域存储桶的建议方法是什么？

Answer 1

您可以尝试执行以下命令

import java.io.*;
import java.util.*;


public class Grades {
    private static ArrayList<Student> sort(ArrayList<String> list) {

        ArrayList<Student> students = new ArrayList<Student>();

        String name = "";
        int grade;

        for (String line : list) {
            String[] splitted = line.split("\\s+");

            for(int i = 0;i< splitted.length-1;i++){
                name += splitted[i] + " ";
            }
            grade = Integer.parseInt(splitted[splitted.length-1]);
            students.add(new Student(name,grade));
            name = "";

        }
        students.sort(Comparator.comparing(student-> student.getGrade()));

        return students;

    } 

    public static void main(String[] args){
        ArrayList<String> list = new ArrayList<>();
        String fileName = "students.txt";
        try (BufferedReader input = new BufferedReader(new FileReader(fileName))) {
            while(input.ready()){
                list.add(input.readLine());
            }
            input.close();
            ArrayList<Student> sortedStudents = sort(list);

            for (Student currentStudent : sortedStudents) 
                System.out.println(currentStudent.getName() + currentStudent.getGrade());                


        } catch (IOException e){
                System.out.println(e.getMessage());
        }
    }
}
