Question

I’ve done this before once, I’m trying to replicate what I did so far and this is what I’ve got:

    try {
        BufferedWriter writer = new BufferedWriter(new FileWriter("file.P", true));
        System.out.println("entered");
        if (!(newUserName.isEmpty()) || (newUserPass.isEmpty())){
            writer.newLine();
            writer.write("hellotest123");
            writer.close();
        }

It seems to find file.P, which is just a txt file, but it doesn’t seem to append anything onto it? It enters the code and passes the IF statement fine, but nothing is appended to the text file? I’m slightly stuck!

Answer 1

Are you sure it is finding file.P and not just creating a new one elsewhere in the file system? Try an absolute path, just to make certain you and the program are looking at the same file.

Edit:

Based on the comment that the file is on the class path you should be using the following method of resolving it:

MyClass.class.getResource("file.P");

This will find file.P on the classpath in the same “package” or folder as MyClass.class
