I have been an engineer for half a year since joining the company, but the other day I passed Java Silver. Since it is a great deal, I will write down the study method and the way to pass here.
・ Study start time: Mid-July 2018 ・ Examination date: August 29, 2018
I was able to pass the exam after studying for about a month and a half.
・ I just finished 3 months of development training ・ A state in which you have some understanding of the contents of up to Chapter 3 of Java Introduction and Practice ・ During the training, I wrote a program in Java or created a web application in jsp. ・ I have just been assigned and have no practical experience.
The following two reference books were used.
・ [Thorough capture Java SE 8 Silver problem collection [1Z0-808] correspondence] (https://www.amazon.co.jp/%E5%BE%B9%E5%BA%95%E6%94%BB%E7%95%A5-Java-Silver-%E5%95%8F%E9%A1%8C%E9%9B%86-1Z0-808/dp/4844339931) → So-called black book. This book is the center of studying Java Silver.
・ [Introduction to Java that is refreshingly understood, 2nd edition](https://www.amazon.co.jp/%E3%82%B9%E3%83%83%E3%82%AD%E3%83%AA% E3% 82% 8F% E3% 81% 8B% E3% 82% 8B-Java% E5% 85% A5% E9% 96% 80-% E5% AE% 9F% E8% B7% B5% E7% B7% A8 -% E7% AC% AC2% E7% 89% 88-% E3% 82% B9% E3% 83% 83% E3% 82% AD% E3% 83% AA% E3% 82% B7% E3% 83% AA % E3% 83% BC% E3% 82% BA / dp / 4844336770) → I used this book when studying lambda expressions.
To be honest, you can pass this alone.
As a matter of fact, in the actual exam, ** many questions are asked with the same contents as the black book but with different values and variable names **, so it is a shortcut to pass the exam.
Basically, I studied for about 30 minutes every day on the commuter train. Only when solving mock questions, I secured about 5 days and about 2 and a half to 3 hours after returning home to study.
The total study time is ** 30-40 hours **.
I will introduce the study method that I actually did.
** 1st lap ** I struggled because I was surprised to find detailed contents that are not included in the introduction to Java and the practical edition. Although it depends on the field, the correct answer rate at this point was about 40%.
** 2nd lap ** Since I entered the second lap without properly reviewing what I should remember, the percentage of correct answers was only slightly higher than in the first lap. Therefore, for the content that I could not memorize at this point, I decided to underline the explanation of the black book and attach a sticky note. ** ** By doing this, I was able to clearly understand what I was not good at, and I was able to review efficiently after the third lap.
** 3rd lap ** In the third lap, the correct answer rate rose to about 80%. JavaSilver has a lot of detailed knowledge, but ** If you solve the black book many times, that knowledge will come to your mind naturally. ** ** Therefore, it is important to continue to solve even if it is difficult.
Lambda expressions and functions are difficult to understand just by looking at Kuromoto's problems and explanations, so I decided to read and study the practical edition. However, there are many problems that you can get points just by learning the basic grammar of lambda expressions **, so you don't have to study that deeply. When I actually took the exam, I only got one question for the lambda expression, so I think it's okay to throw it away at worst.
** Score rate on the first lap ** Chapter 10: Score rate 65% Chapter 11: Score rate 55%
** Score rate on the second lap ** Chapter 10: Score rate 85% Chapter 11: Score rate 80%
I studied the whole range and tried the mock questions with full satisfaction, but the result of the first lap was disappointing.
To be honest, I was quite impatient, but it's okay if I review the mistaken questions as before and get them ready to solve by the exam. Since many questions will be asked in the actual exam, it is important to review the practice exam as well. ** **
Kuromoto's questions have check boxes, so from the third lap onward, I checked the wrong questions and reviewed those questions. Just before the exam, I was able to answer almost all the questions correctly.
Passed with a score rate of 82%. The passing line is 65%, so I had a lot of room.
I passed Java Gold in my first year of graduation, so I will talk about study methods
