部分正确答案:

import java.util.Scanner;public class Main {    public static void main(String[] args) {        Scanner sc = new Scanner(System.in);        int sum=sc.nextInt();        String[][] str = new String[sum][3];        for (int i=0; i

 

使用BufferedReader优化了任然无法通过全部的样例

import java.io.BufferedReader;import java.io.InputStreamReader;import java.util.ArrayList;//import java.util.List;public class Main {    static class Stu {        String id;        int test;        int seat;        public Stu(String id, int test, int seat) {            this.id = id;            this.test = test;            this.seat = seat;        }    }    public static void main(String[] args) throws Exception {        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));        int n = Integer.parseInt(br.readLine());        ArrayList
     
       list = new ArrayList
      
       ();        for (int i = 0; i < n; i++) {            String[] in = br.readLine().split(" ");            Stu s = new Stu(in[0], Integer.parseInt(in[1]), Integer.parseInt(in[2]));            list.add(s);        }        int tn = Integer.parseInt(br.readLine());        String[] search = br.readLine().split(" ");        br.close();        for (int i = 0; i < search.length; i++) {            for (Stu a : list) {                if (a.test == Integer.parseInt(search[i])) {                    System.out.println(a.id + " " + a.seat);                }            }        }    }}
