[Java lista] Fwd: Array join

[Peter Verhas]

Ezt éppen most követtem el (még nincs kidebuggolva)

    public static String join(Collection s, String delimiter) {
        StringBuffer buffer = new StringBuffer();
        Iterator iter = s.iterator();
        while (iter.hasNext()) {
            buffer.append(iter.next());
            if (iter.hasNext()) {
                buffer.append(delimiter);
            }
        }
        return buffer.toString();
    }

    private String absolute(String currentPath, String relativePath) {
        if (relativePath.startsWith("/")) {
            return relativePath;
        }
        String fullPath = currentPath + "/" + relativePath;
        fullPath = fullPath.replaceAll("//", "/");
        ArrayList<String> pathParts =
                new ArrayList(Arrays.asList(fullPath.split("/")));
        int i = 0;
        while (i < pathParts.size()) {
            if (pathParts.get(i).equals("..")) {
                pathParts.remove(i);
                if (i > 0) {
                    pathParts.remove(i - 1);
                }
            } else {
                i++;
            }
        }
        fullPath = join(pathParts, "/");
        return fullPath;
    }
