I'm getting problem in accessing file from other computer in the network. computer drive is shareble.

import java.io.FileReader;
import java.io.FileWriter;
import java.io.BufferedReader;
import java.io.PrintWriter;
import java.io.IOException;

public class ReadWriteTextFile {

private static void doReadWriteTextFile() {

try {

// input/output file names
String inputFileName = "\\\\C:\\demo.java";
String outputFileName = "C:\\Demo\\demo1.java";

// Create FileReader Object
FileReader inputFileReader = new FileReader(inputFileName);
FileWriter outputFileReader = new FileWriter(outputFileName);

// Create Buffered/PrintWriter Objects
BufferedReader inputStream = new BufferedReader(inputFileReader);
PrintWriter outputStream = new PrintWriter(outputFileReader);

// Keep in mind that all of the above statements can be combined
// into the following:
//BufferedReader inputStream = new BufferedReader(new FileReader("README_InputFile.txt"));
//PrintWriter outputStream = new PrintWriter(new FileWriter("ReadWriteTextFile.out"));

outputStream.println("+---------- Testing output to a file ----------+");

String inLine = null;

while ((inLine = inputStream.readLine()) != null) {

outputStream.println("+---------- Testing output to a file ----------+");


} catch (IOException e) {




public static void main(String[] args) {


Error i'm getting

java.io.FileNotFoundException: \\C:\demo.java (The filename, director
y name, or volume label syntax is incorrect)

In ...

... you needed four back-slashes at the start. That's because you really want two back-slashes, but you need an extra back-slash to "escape" each one.

Of course, such a path only works in the world of Windows. Have you considered using "file:" URLs instead, which might be more portable?
