Question

I am creating a file in java using

BufferedWriter out = new BufferedWriter(new FileWriter(FileName));          
StringBuffer sb=new StringBuffer();
sb.append("\n");
sb.append("work");
out.write(sb.toString());
out.close();

But this file is getting created inside the bin folder of my server.I would like to create this file inside a user-defined folder.

How can it be achieved.

I would like to create this file inside a user-defined folder.

The simplest approach is to specify a fully qualified path name. You could select that as a File and build a new File relative to it:

File directory = new File("/home/jon/somewhere");
File fullPath = new File(directory, fileName);
BufferedWriter writer = new BufferedWriter(
    new OutputStreamWriter(
        (new FileOutputStream(fullPath), charSet));
try {
    writer.write("\n");
    writer.write("work");
} finally {
    writer.close();
}

Note:

• I would suggest using a FileOutputStream wrapped in an OutputStreamWriter instead of using FileWriter, as you can’t specify an encoding with FileWriter
• Use a try/finally block (or try-with-resources in Java 7) so that you always close the writer even if there’s an exception.
