این نرم افزار را با استفاده از کد های اینجا و با مساعدت سرکار خانم شایسته علوی نوشتم!

چگونه از یک فایل بخوانیم یا بر روی یک فایل بنویسیم!

با دو برنامه زیر می توانید بر روی یک فایل یک متن بنویسید و دوباره آن را بخوانید!

import java.io.*;

public class MyFirstFileWritingApp
{
 // Main method
 public static void main (String args[])
 {
  // Stream to write file
  FileOutputStream fout;  

  try
  {
      // Open an output stream
      fout = new FileOutputStream ("myfile.txt");

      // Print a line of text
      new PrintStream(fout).println ("hello world!");

      // Close our output stream
      fout.close();  
  }
  // Catches any error conditions
  catch (IOException e)
  {
   System.err.println ("Unable to write to file");
   System.exit(-1);
  }
 } 


}

این برنامه ساده یک فایل متنی میسازد و یک خط از متن روی آن مینویسد!

برای خواندن از روی یک فایل نیز از برنامه زیر استفاده کنید

import java.io.*;

public class MyFirstFileReadingApp
{
 // Main method
 public static void main (String args[])
 {
  // Stream to read file
  FileInputStream fin;  

  try
  {
      // Open an input stream
      fin = new FileInputStream ("myfile.txt");

      // Read a line of text
      System.out.println( new DataInputStream(fin).readLine() );

      // Close our input stream
      fin.close();  
  }
  // Catches any error conditions
  catch (IOException e)
  {
   System.err.println ("Unable to read from file");
   System.exit(-1);
