Absolute to Relative File Path in Java
absolute-path, java, relative-path
Solution
This question was asked before here
Here is the answer just in case
String path = "/var/data/stuff/xyz.dat";
String base = "/var/data";
String relative = new File(base).toURI().relativize(new File(path).toURI()).getPath();
// relative == "stuff/xyz.dat"
Problem
Given I have two `File` objects I can think of the following implementation: ``` public File convertToRelative(File home, File file) { final String homePath = home.getAbsolutePath(); final String filePath = file.getAbsolutePath(); // Only interested in converting file path that is a // direct descendants of home path if (!filePath.beginsWith(homePath)) { return file; } return new File(filePath.substring(homePath.length()+1)); } ``` Is there some smarter way of converting an absolute file path to a relative file path?
