java简单问题 请大家解答

Question

import java.util.Scanner;
import java.util.List;
import java.util.ArrayList;
import java.util.stream.Collectors;

class Student{
    public String name;
    public String id;
    public double score;
    public int num=0;
    num=scanner.nextInt();
    
    public String getName(){
        return name;
    }
    public void setName(String name){
        this.name=name;
    }
    public Stirng getId(){
        return id;
    }
    public void setId(String id){
        this.id=id;
    }
    public double getScore(){
        return score;
    }
    public void setScore(double score){
        this.score=score;
    }
    public static List<Student>students(){
        List<Student>students=new ArrayList<>();
        Student students=new Student();
        for(i=0;i<=num;i++){
        students.setName=scanner.next();
        students.setId=scanner.next();
        students.setScore=scanner.nextDouble();
        }
    }
    public static List<Student> filter(List<Student> students){
        for(i=0;i<=num;i++){
            if((score>=90)&&(score<=100)){
                System.out.println(List<Student>students)
            }
        }
    }
}

public class Main{
    public static void mian(String[] args){
        Student stu=new Student();
        List list=new ArryList();
        students.List<Student> filter(List<Student> students)();
       
   
    }
}

涉及到的知识点我还没学到 我只能临时补看视频 但报错仍然非常多 请问大家我该怎么修改呢

Answer 1

filter里面应该取list里的实例变量，students.get(i).score
