▼ Test results Study period: 3 months Score rate: 73% (border 65%), quite close (> o <)!
Java 8 added a lot of new features, so I took the exam to learn them. First, take the Upgrade to Java SE 8 OCP I was thinking, Since there was no reference book and the amount of information was small, I decided to receive it.
The number of questions was 85 and the exam time was 150 minutes, but there was no shortage of time and it took about 120 minutes to solve. The difficulty level is a little higher than the total finishing problem of Kuromoto. There are few problems such as poking the corner of the heavy box as in Java programmer SE 6 The main new functions of Java8 were stream AIP, lambda expressions, and method references, which accounted for 1/4 of the questions by themselves or in connection with others. In the Study Guide, there were many difficult problems with parallel streams, but in the actual production, there were only two simple problems. There were surprisingly few questions about Optional and DateTime API, and it was about one or two questions. JDBC had a problem related to exception handling, so it was surprisingly large with 5 to 7 questions. For New IO, you need to understand the difference in behavior between absolute and relative paths.
In terms of points, I passed the test at the last minute. .. .. When working on the problem collection, I feel that it was necessary not only to be able to derive the correct answer, but also to understand the background for each option. However, I've organized all the major new features of Java 8, and I think it's a good understanding for business use. The exam preparation was only a collection of questions, but after the exam [Oracle official website](http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=5001&get_params=p_exam_id:1Z0-809&p_org_id = 70 & lang = JA), I found that all the questions were given to each of the exam contents> checklist> [topic], so I should have seen them before the exam. I feel that. I also chose Kuromoto and Study Guide for studying English, but when I saw the blogs of other people, I felt that I could pass if I bought Kuromoto and Purple Book and made two laps each.
