Question

I’m wondering if exist some way to check if a file exist without create an instance of java.io.File

Always I have used the following way:

File f = new File("./path/to/file");
if (f.exists()) {
    doSomething();
}
else {
    manageError();
}

But know I need check some filepaths in order to create elements like a logger (with log4j), xml editor and other project structures, but I don’t need work with them.

For this reason I want to know if this is possible.

I’m using J2SE-1.5_22.

Thanks in advance!

I don’t see what’s wrong with what you’re already doing. Creating an instance of File isn’t going to create the file on disk or anything. You could always write a static method if you want:

public static boolean checkFileExists(string path)
{
    return new File(path).exists();
}

If that doesn’t satisfy your requirements, please explain what you’re trying to do that doesn’t work with this.
