Obtained Oracle Certified Java Programmer Silver SE 8 Examination experience

A long time ago states "Aiming to acquire Oracle Java SE8 Silver".

Last month, I finally did what I said, so I will describe how to study until passing and the test experience.

Java skills before my study

--Understand the basic grammar (if, for, while, how to use API, etc.) --Business experience only modifies a dozen lines of source code (7 years ago) --VB.net, PL / SQL has a solid implementation experience in business (5 years ago) ――Take Java for 4 months at a programming school 2 months ago --Object-oriented is not so much (interfaces, constructors, inheritance, etc.)

I tried to get it as an output of taking Java for 4 months at a programming school.

Text used for study

--Oracle Certification Textbook Java Programmer Silver SE 8 Speedmaster Questions (Shiramoto)

--Thorough capture Java SE 8 Silver problem collection [1Z0-808] compatible (hereinafter black book)

--A book that understands Java's object-oriented programming

Study period

About an hour and a half a day for a month

Study flow

In the first 1.5 weeks, I repeated only the problem that I made a mistake in the white book and repeated 5 laps So that you can solve all the problems without making a mistake

Now that you're familiar with the basic Java grammar and question format, Looking at the reviews of amazon etc., it seems that the actual problem is quite difficult

After that, I spent a week on Kuromoto in about 4 days. Basic grammar, branching, loops, API problems can be solved smoothly, Even if you make a mistake, if you read the commentary, "Oh, that's right." I can understand that

Only object-oriented issues : upside_down: ** I can't understand even if I read the explanation **: upside_down:

Because the words such as interface and constructor and the source are not tied in my head Even if you read the commentary, it's refreshing

I think this is bad To get a solid understanding of object orientation "A book that understands Java's object-oriented programming" Purchase and read through in about 3 days

Then mysterious As Kuromoto's object-oriented commentary, which was refreshing until now, comes to mind

Like white books, black books take about 1.5 weeks I made about 5 laps until there were no unsolvable problems.

Three laps of Kuromoto's "total finishing problem" from one week before the exam I went to the exam.

Test results

Passed successfully with a correct answer rate of 88% (passed with 66%)

Impressions

Surprisingly affordable Maybe I didn't need 5 laps of Shiramoto Many questions similar to Kuromoto's "total finishing question" were asked. However, most problems cannot be solved without understanding object orientation.

Currently, I changed jobs and wrote Java, I'm glad I studied I really think. (Especially the object-oriented concept really helps)

next time?

We are planning to be an applied information engineer or an AWS association. If you pass, I will write an article there as well I will do my best.
