NEW QUESTION 88
......


Given that this exam is at the professional level of certification, candidates have a large amount of work to do. Therefore, the first thing that is recommended is to thoroughly review the complete list of topics available on the official exam page, which includes:

  • Exceptions and Assertions. In other words, how to use try-catch and throw statements, alongside creating custom exceptions and Auto-closeable resources.
  • Stream API. It means the code development that uses optional class, Stream data, and calculation methods in addition to sorting a collection using Stream API.
  • NIO.2, Path Interface, and Files Class.
  • Generics and Collections. This allows the candidate to create and use a generic class as well as ArrayList, TreeSet, TreeMap, and ArrayDeque objects.
  • Java Concurrency. The candidates must be able to create worker threads, as well as to use parallel Fork/Join Framework and parallel Streams.
  • Localization. In particular how to read and set the locale by using the Locale object, to create and read a Properties file, and to build a recourse bundle for each locale.

To apply for this Oracle certification test, you should first pay $245 for a voucher. After that, go to Pearson VUE and log into your account. Enter the exam code, which should be 1Z0-809, and follow the instructions that will pop up.
