Vector

find(File pDirectory, String pRegex)

Vector<File> lReturn = new Vector<File>();
lReturn = find(lReturn, pDirectory, new RegExpFileFilter(pRegex));
return lReturn;

File[]

Finds all files (non-recursively) in a directory based on the FileFilter.

if (!dir.exists()) {

if (!dir.isDirectory()) {
    throw new FileNotFoundException("File " + dir
            + " is not a directory.");
ArrayList<File> files = new ArrayList<File>();
File[] allFiles = dir.listFiles();
if (allFiles != null && allFiles.length > 0) {
    for (File f : allFiles) {
        if (f.isFile()) {
            if (filter.accept(f)) {
                files.add(f);
File[] r = files.toArray(new File[0]);
Arrays.sort(r);
return r;

String

recursiveSearch(java.io.File dir, String fileName)
Recursive method for searching file path.

for (String name : dir.list()) {

            + "/" + name);
    if (name.compareTo(fileName) == 0)
        return file.getAbsolutePath();
    if (file.isDirectory()) {
