Hi Friend,

Please try the following sample code to solve your problem. In this code we a text file from where the input is to be taken and then this input text will be further replaced with the suitable values.

Code
======

import java.io.*;
import java.net.*;

public class RewriteFile{

public static void main(String args[]) throws Exception,MalformedURLException {

FileInputStream instream = new FileInputStream("mttextfile.txt");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(instream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));

String line="";

String result="";
FileWriter fstream = new FileWriter("out.txt");
BufferedWriter output = new BufferedWriter(fstream);
while((line=br.readLine())!= null) {

if(line.equals("php")){
result+="j2me"+"\n";
}
else
{
result+=line+"\n";
}
}
output.write(result);
output.close();
br.close();
}
}

Thanks for posting question.
