逐行读取数据，并查找特定数据

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.InputStreamReader;

public class Solution {
    public static void main(String[] args) throws Exception{
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        String name = reader.readLine();
        FileReader file = new FileReader(name);
        BufferedReader file2 =  new BufferedReader(file);
        int id = Integer.parseInt(args[0]);
        String s = null;
        while ((s = file2.readLine()) != null) {
                String[] temp = s.split(" ");
                if (id ==  Integer.parseInt(temp[0])){
                    System.out.println(s;
                }

            }
        reader.close();
        file.close();
        file2.close();
        }

    }
