mkdir     creates only one directory at a time  if it is parent that one only  other wise it can create the sub directory if the specified path is existed only  and do not create any directories in between any two directories  so it can not create smultiple directories in one directory   mkdirs     create the multiple directories in between two directories also  at a time

mkdirs   will create the specified directory path in its entirety where mkdir   will only create the bottom most directory  failing if it can t find the parent directory of the directory it is trying to create   In other words mkdir   is like mkdir and mkdirs   is like mkdir -p   For example  imagine we have an empty  tmp directory   The following code  new File   tmp one two three   mkdirs      would create the following directories     tmp one  tmp one two  tmp one two three   Where this code   new File   tmp one two three   mkdir      would not create any directories - as it wouldn t find  tmp one two - and would return false

mkdirs   also creates parent directories in the path this File represents   javadocs for mkdirs        Creates the directory named by this abstract pathname  including any   necessary but nonexistent parent directories  Note that if this   operation fails it may have succeeded in creating some of the   necessary parent directories    javadocs for mkdir        Creates the directory named by this abstract pathname    Example   File  f   new File  non existing dir someDir    System out println f mkdir     System out println f mkdirs       will yield false for the first  and no dir will be created   and true for the second  and you will have created non existing dir someDir
