I'm reading in file names as Strings. I don't know how long these file names will be but I know that all end in .txt. I want to remove the .txt leaving only the file name. Any ideas?

    Well, there's the obvious approach of checking that the string *does* end with `.txt`, and just taking a substring based on the original length - 4... have you tried that? – Jon Skeet May 03 '13 at 15:37

    *"Any ideas?"* Yes. Search the forum and show some effort before asking. – Andrew Thompson May 03 '13 at 15:55

 int dot = file.getFileName().toString().lastIndexOf(".");
 String me = "File: " + file.getFileName().toString();
 System.out.println("File: " + file.getFileName().toString().substring(0,dot+1));

yourString.subtring(0, yourString.length()-4);

if(filepath.endsWith(".txt") {
    filepath = filepath.substring(0, filepath.lastIndexOf(".txt");
}

If (filename.endsWith(".txt")) {
    filename = filename.substring(0, filename.length()-4);
}

Or:

filename = filename.replace(".txt", "");

(will also cut away any .txt inside but not at the end of the file)
