JAVA

java get all directories in path

A very simple Java 8 solution:
File[] directories = new File("/your/path/").listFiles(File::isDirectory);

It's equivalent to using a FileFilter (works with older Java as well):
File[] directories = new File("/your/path/").listFiles(new FileFilter() {
    @Override
    public boolean accept(File file) {
        return file.isDirectory();
    }
});
