How to use short path when writing a file

Question

When I getting something in my code I use a short path like

this.getStylesheets().add("/css/editorTool.css");

but when I writing a new file I give exact paht - like:

File f = new File("D:\\IdeaProjects\\SmartCRM for TB\\EditorTool\\resourses\\html\\test.html");
    try{
            BufferedWriter bw = new BufferedWriter(new FileWriter(f));
            bw.write(html);
            bw.close();

        } catch (IOException e) {
            e.printStackTrace();
        }

As i will have to distribute this app among some users I will not be able to garanty that the absolute path to my app will be the same. How i can write it to so that it is like "path_to_the_folder_that_is_contained_in_app + fileName?

Answer 1

you can use system property "user.dir" to get current working path, the code is alike this:

String currentWorkingPath = System.getProperty("user.dir");
String fullPath = currentWorkingPath  + File.separator+ fileName;

then the file will be under currentWorkingPath when the program run on any PC.

Answer 2

You can use getResource() method of java.lang.Class<T>

The java.lang.Class.getResource() finds a resource with a given name

usage:

File file = new File(getClass().getResource("html/test.html").getPath());
