PAT 乙级 1041. 考试座位号(15) Java版

每个PAT考生在参加考试时都会被分配两个座位号，一个是试机座位，一个是考试座位。正常情况下，考生在入场时先得到试机座位号码，入座进入试机状态后，系统会显示该考生的考试座位号码，考试时考生需要换到考试座位就座。但有些考生迟到了，试机已经结束，他们只能拿着领到的试机座位号码求助于你，从后台查出他们的考试座位号码。

输入格式：

输入第一行给出一个正整数N（<=1000），随后N行，每行给出一个考生的信息：“准考证号试机座位号考试座位号”。其中准考证号由14位数字组成，座位从1到N编号。输入保证每个人的准考证号都不同，并且任何时候都不会把两个人分配到同一个座位上。

考生信息之后，给出一个正整数M（<=N），随后一行中给出M个待查询的试机座位号码，以空格分隔。

输出格式：

对应每个需要查询的试机座位号码，在一行中输出对应考生的准考证号和考试座位号码，中间用1个空格分隔。

输入样例：

对输入方式优化了一下，用Scanner读输入用时太长，改了一下输入方式

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {

	public static void main(String[] args) throws IOException{
		BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(System.in));
		int n = Integer.parseInt(bufferedReader.readLine());
		Student[] students = new Student[n];
		for (int i = 0; i < n; i++) {
			String[] strings = bufferedReader.readLine().split(" ");
			students[i] = new Student(strings[0], strings[1], strings[2]);
		}
		
		int m = Integer.parseInt(bufferedReader.readLine());
		String[] test = bufferedReader.readLine().split(" ");
		for (int i = 0; i < m; i++) {
			String findTestSite = test[i];
			
			for (int j = 0; j < n; j++) {
				if (students[j].testSite.equals(findTestSite)) {
					System.out.println(students[j].id + " " + students[j].correctSite);
				}
			}
		}
		bufferedReader.close();
	}
