Read and Write.. it was working

[javauserjava]

Hi everyone,

I have this code since last year and now I would like to reuse it again. but right now I run it and there was no error but also there is no result.

Could anyone help me please ,,

import java.io.*;

public class ReadAndWrite{



public static void main(String args[]) throws IOException {
    if(args.length !=2)
	return;
    BufferedReader inStream         
	= new BufferedReader (new FileReader("C:\\Temp\\ReadAndWrite\\File1.txt"));// to open the read stream
   
    FileWriter outStream = (new FileWriter("C:\\Temp\\ReadAndWrite\\File2.txt"));// to open the write stream

    String line = inStream.readLine();// put the the sentance in Line
	int r1 = 1;
	while (line != null){
	
 
	    outStream.write(r1+ "" + line +"\n" );// to write 
	    line = inStream.readLine(); // to read the next line
	 r1++;
    }// end while
  

	inStream.close(); // close the input file
	outStream.close (); // close the output file                         

   
}//end main
}// end class

C:\\Temp\\ReadAndWrite\\File1.txt - does this file still exist?

I fixed your code for you. Also make sure that these files exist.

import java.io.*;

public class ReadAndWrite{

public static void main(String args[]) throws IOException {
    if(args.length !=2)
	return;
    BufferedReader inStream         
	= new BufferedReader(new File("C:\\Temp\\ReadAndWrite\\File1.txt"));// to open the read stream
   
    BufferedWriter outStream = new BufferedWriter(new PrintWriter(new File("C:\\Temp\\ReadAndWrite\\File2.txt")));// to open the write stream

    String line;
	int r1 = 1;
	while ((line=inStream.readLine()) != null){
	    outStream.write(r1+ "" + line +"\n" );// to write
	 r1++;
    }// end while

	inStream.close(); // close the input file
	outStream.close (); // close the output file                         
}//end main
}// end class
