I was doing java in the training. There was a space before that, so [Introduction to Java that you can understand clearly](https://www.amazon.co.jp/ Introduction to Java that you can understand clearly-3rd edition-Refreshing series-Kiyotaka Nakayama / dp / 4295007803) and I've been doing paiza for about a month. I managed to solve up to B rank.
I received silver on the last day of the training, and it was 53%. .. ..
89% by retaking the exam! Pass!
Total study period: about 3 months
The first time is lack of study! Was definitely there
The second time is [Kuromoto](https://www.amazon.co.jp/ Thorough capture Java-SE-11-Silver problem collection-1Z0-815 / dp / 4295007625 / ref = pd_lpo_14_t_0 / 355-2169576-6249117? _encoding = UTF8 & pd_rd_i = 4295007625 & pd_rd_r = fbcae4b0-48fd-4bf8-bcc1-ebdb9fa90b30 & pd_rd_w = 7JXDG & pd_rd_wg = 329ry & pf_rd_p = 4b55d259-ebf0-4306-905a-7762d1b93740 & pf_rd_r = YZTBQMR58WS3SB177MWK & psc = 1 & refRID = YZTBQMR58WS3SB177MWK) like crazy solving, level of much late should not be allowed out only perfect score was.
Speaking of Java ・ Check the override specifications carefully ・ Check the access modifier carefully ・ Local variables and field priorities ・ Constructor specifications -As for exception handling, lambda expression, and module system, the pattern to be asked is similar to Kuromoto, so I will remember it. (It's not so good ...)
・ It may not be very helpful, but for modules, I had the impression that the roles and basic APIs were summarized in base. There were many problems that asked for knowledge.
It will be very helpful, so please do!
If you really do the certified textbook series, you can accept it!
Next, I want to receive basic information or LPIC, and I want to make something I also want to write a technical article
