Converting Relative Paths to Absolute Paths

Question

I have an absolute path to file A.

I have a relative path to file B from file A\'s directory. This path may and will use \"..\" to go up the directory structure in

Answer 1

If I get your problem right, you could do something like this:

File a = new File("/some/abs/path");
File parentFolder = new File(a.getParent());
File b = new File(parentFolder, "../some/relative/path");
String absolute = b.getCanonicalPath(); // may throw IOException
