  • Use Executor, ExecutorService, Executors, Callable, and Future to execute tasks using thread pools.
  • Use the parallel Fork/Join Framework
• Localization
  • Describe the advantages of localizing an application
  • Define a locale using language and country codes
  • Read and set the locale with a Locale object

  • Operate on file and directory paths with the Path class
  • Check, delete, copy, or move a file or directory with the Files class
  • Read and change file and directory attributes, focusing on the BasicFileAttributes, DosFileAttributes, and PosixFileAttributes interfaces

  • Find a file with the PathMatcher interface
  • Watch a directory for changes with the WatchService interface
