Java Utililty Methods Recursive List

File[] recursiveList(File dir, FilenameFilter filter)
recursive List

Vector v = new Vector();
addRecursiveList(dir, filter, v);
File[] files = new File[v.size()];
v.copyInto(files);
return files;

List recursiveListFile(File folder)
recursive List File

return recursiveListFile(folder, "", f -> true);

List recursiveListFiles(File baseDir, final FileFilter filter)
recursive List Files

FileFilter dirFilter = new FileFilter() {
 public boolean accept(File pathname) {
 return pathname.isDirectory() || filter.accept(pathname);
};
File[] fileArray = baseDir.listFiles(dirFilter);
List<File> files = new ArrayList<File>(fileArray.length);
for (int i = 0; i < fileArray.length; i++) {

File[] recursiveListFiles(File dir, FileFilter filter)
recursive List Files

if (!dir.isDirectory())
 throw new IllegalArgumentException(dir + " is not a directory");
List<File> fileList = new ArrayList<File>();
recursiveListFilesHelper(dir, filter, fileList);
return fileList.toArray(new File[fileList.size()]);

void recursiveListFiles(File file, List files)
recursive List Files

for (File f : file.listFiles()) {

List recursiveListFiles(String path)
recursive List Files

List<File> result = new ArrayList<File>(Arrays.asList(new File(path).listFiles()));
for (File f : new File(path).listFiles())
 if (f.isDirectory())
 result.addAll(recursiveListFiles(f.getAbsolutePath()));

void recursiveListFilesHelper(File dir, FileFilter filter, List fileList)
recursive List Files Helper

for (File f : dir.listFiles()) {
 if (f.isDirectory()) {
 recursiveListFilesHelper(f, filter, fileList);
 } else {
 if (filter.accept(f))
 fileList.add(f);

void recursiveListint(List list, File file, FilenameFilter filter)
If the parameter file is a file then it is added to the list of files.

if (file.isFile()) {
 list.add(file);
} else {
 File[] children = null;
 if (filter != null) {
 children = file.listFiles(filter);
 } else {
 children = file.listFiles();
...

SortedSet recursiveListPartialPaths(File parent, boolean includeDirs)
Recursively lists a directory, returning the partial paths of the child files.

assert parent != null;
TreeSet<String> toReturn = new TreeSet<String>();
int start = parent.getAbsolutePath().length() + 1;
List<File> q = new LinkedList<File>();
q.add(parent);
while (!q.isEmpty()) {
 File f = q.remove(0);
 if (f.isDirectory()) {
