Hi Friend,

please try this code. It is taking the input from the console.

import java.io.*;
class FileWrite
{
public static void main(String args[])
{
try{

Console console = System.console();

if (console == null) {
System.err.println("No console found");
System.exit(0);
}
// Create file
FileWriter fstream = new FileWriter("out.txt",true);
BufferedWriter out = new BufferedWriter(fstream);
out.write(console.readLine());
//Close the output stream
out.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
}
