Method

Filemkdirs(File dir)
mkdirs 
if (!dir.exists()) {
    dir.mkdirs();
return dir;
booleanmkdirs(File dir)
Just a simple wrapper around `java.util.File.mkdirs()` that fails when trying to create a folder named "~" 
String path = dir.getPath().replace('\\', '/');
if (path.equals("~") || path.startsWith("~/") || path.contains("/~/")) {
    return false;
return dir.mkdirs();
Filemkdirs(File dir)
mkdirs 
if (dir == null)
    return null;
if (!dir.exists() && !dir.mkdirs())
    throw new RuntimeException("ERROR: mkdirs: " + dir);
return dir;
booleanmkdirs(File directory)
Creates a new directory. 
if (directory.exists())
    return false;
if (!directory.mkdirs())
    throw new IOException("cannot create the directory: " + directory);
return true;
voidmkdirs(File directory)
Method description 
if (!directory.exists() && !directory.mkdirs()) {
    throw new IllegalStateException("could not create directory ".concat(directory.getPath()));
booleanmkdirs(File directory)
mkdirs 
if (directory == null) {
    return false;
if (directory.exists()) {
    return false;
if (directory.mkdir()) {
    return true;
...
Filemkdirs(File directory, String string)
mkdirs 
File path = new File(directory, string);
mkdirs(path);
return path;
voidmkdirs(File dirs)
CreatingUtils all folders at once. 
if (dirs.exists()) {
    if (dirs.isDirectory() == false) {
        throw new IOException("Directory '" + "' is not a directory.");
    return;
if (dirs.mkdirs() == false) {
    throw new IOException("Unable to create directory '" + dirs + "'.");
...
booleanmkdirs(File dumpFile)
mkdirs 
File dir = dumpFile.getParentFile();
return dir.exists() || dir.mkdirs();
voidmkdirs(File f)
A hopefully more robust to concurrent creation mkdirs method: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4742723 
if (f.mkdir() || f.exists()) {
    return;
File canonFile;
try {
    canonFile = f.getCanonicalFile();
} catch (IOException e) {
    return;
