NoSuchFileException java

So I’m currently working on a java fx project and I am trying to get my program to read 2 txt files (name.txt) and (password.txt). When I run this in IntelliJ it works as intended but when I run the jar file in power shell I get this:

the code that is supposed to tell where to look at the text files are this:

    public String getName() throws IOException{
        return new String(Files.readAllBytes(Paths.get("details/name.txt").toAbsolutePath()));
    }

    public String getPass() throws IOException{
        return new String(Files.readAllBytes(Paths.get("details/password.txt").toAbsolutePath()));
    }

Also the .txt files are in the project folder

Answer

From your stacktrace, I see that the file in question is “C:Usersybalddetailsname.txt”. If it’s not found, it’s probably not there, and so I guess you used a relative path. The path is relative to the directory your started the jvm in. Your IDE uses another directory than you do when you start your program unfroh the shell.

Use an absolute path, and it will work. You can use dir.resolve(filename) to turn your relative path into an absolute one.
