Path for a file on a Mac without the username in Java

1 answer

I want to be able to open a text file with some basic instruction from within a program in Java, What I currently have to open the file:

Desktop desktop = Desktop.getDesktop(); File file = new File(/* File Path, this is what I am concerned with. */); if(file.exists()) try {      desktop.open(file); } catch (IOException e) {e.printStackTrace();} 

This works fine, what I have been using for the path is:

"/Users/Box/Documents/text.txt"

The reason I have a problem is because I want to send my program to a friend so that he can try it out. The current solution I have is to have a text field that the user can input their username into and then the path is:

"/Users/" + username + "/Documents/text.txt" (username being the username that is inputed into the text field)

Where else could I store the file or what else could I use for a path? Is there a way to find the user automatically? Should I store the file in a folder made in the root?

All answers to this question, which has the identifier 61078070

The best answer:

If you like to use a fixed path under the user folder, you can get the username via

String username = System.getProperty("user.name"); 

Alternatively you can use a path relative to the location of the program, for example Paths.get("").toAbsolutePath(), see Getting the Current Working Directory in Java
