In the given program, the root directory must be present in the output. As the root directory is not present, options A, B, C and D are incorrect. Option F is also incorrect as the path root/a/b must be right behind the path root/a due to depth-first traversal. In a nutshell, it’s like they took the old OCA 8 exam, increased the difficulty of the questions by an order of magnitude until it was as hard as the old OCP 8 exam. Then, they updated the length of questions so that you had to answer 2-3 questions at once in a single question. Next, they greatly increased the depth of any topic on the previous exam.

Getting Java accredited and recognized is always good for your career, even if you're a junior developer who has just started your career.

Lists the module dependencies and also the package names of JDK internal APIs (if referenced). Analyzes the dependencies of the specified modules.

The format method of DecimalFormat accepts a double value as an argument and returns the formatted number in a String.

If offered, read the exam objectives

I again used the relevant Java SE 17 exam study guide and Enthuware practice tests for this. The Java 17 exam was mostly similar in scope to that of the Java 11 exam, although it felt a bit harder. Questions on JDBC, concurrency and serialisation were more intense and involved than on the Java 11 exam. The study guide also felt a bit inadequate on these topics, so ensure that you read widely and study the relevant Oracle documentation as well.

  • Experience Test-King Oracle 1z0-819 exam Q&A testing engine for yourself.
  • Option A is correct as it does not require any module.

  • The exam requires a minumum of 68% in order to pass.

To pass this exam, you will need a thorough knowledge of the concepts listed in the syllabus. You can take the Java SE 8 training offered by Oracle if necessary. With encapsulation, you define variables and methods in a class and choose which ones to expose outside the class.

She is a senior moderator at CodeRanch, and trains and mentors students of all levels, including the programming division of a FIRST robotics team.

However it’s not a goal of the exam to test the programmer’s ability to produce purposeful or efficient programs. To get to a.txt from the current path of b/c.txt , you need to go up two levels (the file itself counts as one level) and then select a.txt. Calling relativize() is on path2 will get to the path b/c.txt from the current path of a.txt, resulting in the output  “../b/c.txt”.
