สงสัยครับว่าทำไม C++ มันทำไมอ่านไฟล์ช้ากว่า Java ครับ ผมเข้าใจมาว่า C น่าจะไวกว่ามาก หรือเพราะผมเขียน Code ไม่ดีครับ

package readtext;
import java.io.*;
import java.text.SimpleDateFormat;
import java.util.*;

public class Main {

    public static void main(String[] args) {
        Date date = new Date();
        SimpleDateFormat ft = new SimpleDateFormat("E dd.MM.yyyy 'at' hh:mm:ss:SSS a");

        try {
            String file = args[0];
            System.out.println("================================================");
            System.out.println("Start Date : " + ft.format(date));
            System.out.println("================================================");

            FileInputStream fstream = new FileInputStream(file);
            // Get the object of DataInputStream
            DataInputStream in = new DataInputStream(fstream);
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            String strLine;
            //Read File Line By Line
            while ((strLine = br.readLine()) != null) {
               
                String str = strLine;
                //System.out.println(strLine);
            }
            in.close();
            System.out.println("================================================");
            date = new Date();
            System.out.println("End Date : " + ft.format(date));
            System.out.println("================================================");

        } catch (Exception e) {
            System.out.println("\nFile not found!\n");
        }
    }
}
