How to wait on file creation in Java

Here are some steps that we can remember while move in to coding part
  1. Iterate the (!file.exist()) blog till this block becomes as a false . so for that we can use Thread class and do Thread.sleep(10). that will wait for 10ns  and once time has been expire again it start same loop . means every 10 ns it will check on directory whether file is exist or not . if not then iterate.
  2.  once it got the file on directory then while loop iteration will stop and terminate the execution of while block
