Where to use resolve() and relativize() method of java.nio.file.Path class?

Question

Path p1 = Paths.get(\"/Users/jack/Documents/text1.txt\");
Path p2 = Paths.get(\"/Users/jack/text2.txt\");
Path result1 = p1.resolve(p2);
Path result2 = p1.relativize(p2)         


        

Answer 1

These are the code snippets from my code base that help you to understand the use of the resolve() method

private File initUsersText() throws Exception
{
    Path dir = testdir.getPath().toRealPath();
    FS.ensureDirExists(dir.toFile());
    File users = dir.resolve("users.txt").toFile();

    writeUser( users );
    return users;
}


private File initUsersText() throws Exception
{
    Path dir = testdir.getPath().toRealPath();
    FS.ensureDirExists(dir.toFile());
    File users = dir.resolve("users.txt").toFile();

    writeUser( users );
    return users;
}

And these are the examples of the use of relativize()

public ScopePath pathToClassName(Path file) {
    if (!isValidClass(file))
        return null;

    Path relativePath = root.relativize(root.resolve(file));
    String withoutExtension = removeExtension(relativePath.toString());
    return new ScopePath(withoutExtension.replace(File.separator, "."));
}


private String getRelativePath(Path p) {
    String relativePath = packageDir.relativize(p)
            .toString();

    if (File.separator.equals("\\")) {
        relativePath = relativePath.replace("\\", "/");
    }

    return relativePath;
}
