Hi! Another question for Jeanne and Scott

What questions involving Collections and Maps should I expect in the 1z0-815 exam? I expect questions involving Lists, particularly ArrayLists, but I don’t know what level of question to expect. Should I be familiar with all of the List methods?

I (prematurely, see here) attempted the exam before; one of the questions which stumped me involved initialising a field of type Collection with a Map. I thought that was not in scope for this exam, especially as the Oracle prep course I took did not include Maps or Collections. I was wrong. What is in scope for the exam?

Please let me know if this question is too broad or hard to answer. I would just like to know if I’m on the right track to be completely ready for the exam   . Thank you.

I think you got hit by the difference in scope between 1Z0-808 Java 8 OCA) and the 1Z0-815. Oracle added topics to the exam for Java 11. They also moved topics that used to be on the OCP 8 to the OCA 8.

This is why it is important to use a study guide for the exam you are taking. i realize that one didn't exist at the time you were studying. You definitely have to know Lists, Set, Map, sort, search and more.

Collections are one of my favorite things in the Java API... whether they are in scope or not, learn them!  They help on a lot in practice.  I also recommend the Eclipse Collections framework, a lot of really cool stuff in there.

I don't have any previous experience with Java, so this was a case of having no idea of what I should know. I didn't know how serious the test really is, too, so I did not try anything like mock exams, etc   . I know better now! A study guide is key, because you can't tell on your own where the gaps in your knowledge are.

Yes, I am definitely going to. I have to write again soon, though, so I need to budget my study time wisely  . Hopefully I can pull everything together to be properly prepared.
