Absolute path / creating FileWriter-object

[Jesper Sahner]

Hi!

I am creating a FileWriter-object in the following way:

FileWriter file = new FileWriter("myfile.txt");

The file "myfile.txt" is then placed in the directory from where Java
is called, in my setup C:\Program Files\NetBeans 3.6

However I want to place the file "myfile.txt" in the same directory
(package) as the .class-file in which the FileWriter-object is
created.

How do I do this?

Regards,
Jesper

You don't. At least not in a clean way.

You may try to find the part of the classpath where your class resides
(for example "."), and select the correct directory based on the package
name.

This "solution" will come crashing down however, if you:
- package the application in a .jar file, or
- use an URLClassloader, or
- use any other method where classes are not available in an unpacked
directory structure.

*Why* do you want to do that? (See Oscar's answer)

It is generally better to put the file inside a known location
(sub directroy, whatever..) of "user.home".

You can do this to create a file in a specific directory

BufferedWriter out = new BufferedWriter(new FileWriter(directoryPath+folderSeperator+"index.html"));
