The following list of topics is meant to give you an idea of the types of questions and oddities that you might come across on the exam. Being aware of these categories of questions can help you get a higher score on an exam.

 Questions with Extra Information Provided Imagine the question includes a statement that XMLParseException is a checked exception. It's fine if you don't know what an XMLParseException is or what XML is, for that matter. (If you are wondering, it is a format for data.) This question is a gift. You know the question is about exception handling.

 Questions with Embedded Questions To answer some questions on the exam, you may have to answer two or three subquestions. For example, the question may contain two blank lines and ask you to choose the two answers that fill in each blank. In some cases, the two answer choices are not related, which means you're really answering multiple questions, not just one! These questions are among the most difficult and time-consuming on the exam because they contain multiple, often independent, questions to answer. Unfortunately, the exam does not give partial credit, so take care when answering questions like these.

 Questions with Unfamiliar APIs If you see a class or method that wasn't covered in this book, assume that it works as you would expect. Some of these APIs you might come across, such as SecurityManager, were on the Java 11 exam and are not part of the Java 17 exams. Assume that the part of the code using that API is correct, and look very hard for other errors.

 Questions with Made-Up or Incorrect Concepts In the context of a word problem, the exam may bring up a term or concept that does not make any sense, such as saying an interface inherits from a class, which is not a correct statement. In other cases, the exam may use a keyword that does not exist in Java, like struct. For these, you just have to read carefully and recognize when the exam is using invalid terminology.

 Questions That Are Really Out of Scope When introducing new questions, Oracle includes them as unscored questions at first. This allows the exam creators to see how real exam takers do without impacting your score. You will still receive the number of questions the exam lists. However, a few of them may not count. These unscored questions may contain out-of-scope material or even errors. They will not be marked as unscored, so you still have to do your best to answer them. Follow the previous advice to assume that anything you haven't seen before is correct. That will cover you if the question is being counted!

Like all exams, the Oracle Certified Professional: Java SE 17 Developer or Java Foundations Certified Junior Associate certification from Oracle is updated periodically and may eventually be retired or replaced.
