This book does not explain the topics but just presents information as facts that you must remember for answering exam questions. If you are an experienced Java developer or have already learnt the topics required for the exam from another book or course, you can use this book to revise important points before the exam quickly.Some topics such as Concurrency, Streams, Modules, Date API, and Internationalization are covered in detail because the exam contains tough questions on these topics and few developers use these topics at work regularly.IMPORTANTThis book DOES NOT contain mock exams, quizzes, or exercises. It should be used as a compendium of information required to pass the exam.If you like the book, please post a review and purchase a PDF copy from enthuware.com/booksWe enhance the content of this eBook and publish it on Amazon frequently.
