깊이가 남다른 이펙티브 자바 ✨

자바 공부의 끝, 이펙티브 자바.

모든 자바 개발자가 한번쯤 공부를 시도하지만
결코 아무나 정복할 수 없는 책, "이펙티브 자바"
이 강의가 완벽하게 공략해 드립니다.

수준 높은 백엔드 개발자가
되고 싶은 당신을 위해.

『이펙티브 자바(Efftective Java 3/E)』는 모든 자바 개발자에게 권하는 책이지만 역설적이게도 모든 자바 개발자가 쉽게 학습할 수 있는 책은 아닙니다. 제일 첫 번째 아이템부터 제대로 소화하려면 "열거 타입", "플라이웨이트 패턴", "인터페이스의 정적 메서드", "서비스 제공자 프레임워크", "리플렉션" 이라는 배경 지식이 필요합니다. 이런 배경 지식 없이 책의 내용을 100% 이해하기는 어렵습니다. 그만큼 학습하기 어려운 책이지만, 하나씩 학습을 했을때 뒤따르는 보상도 남다릅니다.

『이펙티브 자바』의 내용을 이해하면 여러분의 실력과 지식은 이전에 비해 많이 향상될 것이며, 새로운 시야를 밝혀줄 것입니다. 심지어 다른 프로그래밍 언어를 공부하거나 사용한다 하더라도 말이죠. (마치 이 책을 열심히 공부했었지만 지금은 마이크로소프트에서 C#과 Powershell을 사용하며 일하고 있는 지금의 저처럼 말이죠.)

시리즈로 도전하는
이펙티브 자바 완벽 공략

이펙티브 자바 완벽 공략 - Part 1시리즈 연재 중

『이펙티브 자바』를 총 5부로 나눠서 학습합니다. 그중 1부에 해당하는 이 강의는 『이펙티브 자바』 2장 "객체 생성과 파괴"와, 3장 "모든 객체의 공통 메서드"를 다룹니다.

『이펙티브 자바』 학습을 어려워하는 개발자 또는 학생 또는 보다 완벽하게 학습하고 싶은 분들을 위해 각 아이템을 코드와 함께 요약하고, 각 아이템 별로 학습하는 데 도움이 되는 배경 지식을 전달해 드립니다. 여러분의 『이펙티브 자바』 학습이 훨씬 재미있고, 쉽고 또 유익할 것입니다.

자바 심화 학습이 필요한 분들께.

이 강의는 프로그래밍 초급자 또는 입문자를 위한 강의가 아닙니다. 자바를 사용해 일을 하고 있는 개발자 또는 기본적인 자바 공부를 마치고 보다 수준높은 심화 학습을 통해 실력을 올리고 싶은 개발자 또는 학생을 위한 강의입니다. 다음 강의를 수강했거나 그에 준하는 학습을 했다면 이번 강의를 들어도 좋습니다. (자세한 내용은 섹션 0 - 강의 소개 수업을 참고해 주세요.)

모든 자바 개발자의 필독서,
함께 읽어나갈 수 있도록 💌

공부는 왜 하는 걸까요? 우리는 왜 이런 어려운 것들을 이해하려고 노력하고 시간과 돈을 소비하는 걸까요? 그 답은 여러분의 "실력 향상"이라고 생각합니다. 이 강의는 스프링이나 자바를 공부할 때 사용하던 저의 학습 방식을 그대로 담고 있습니다. 우선 읽어보고, 이해가 되는 내용과 이해가 되지 않는 내용을 정리하고, 이해가 되지 않는 내용은 왜, 어떤 부분 때문인지 요약을 하고 그 부분에 필요한 추가 학습. 그리고 추가 학습에 이어지는 또 다른 추가 학습.

저는 그런 학습 과정을 통해서 진정한 실력이 길러진다고 믿고 있습니다. 초반엔 더디고 힘들겠지만 아이템 13과 14를 학습할 때 쯤의 여러분은 아이템 1과 2를 학습할 때의 여러분과 분명히 달라져 있을 겁니다. 한번 느껴보세요. 이 강의의 마지막 수업까지 본인의 실력이나 지식에 아무런 변화를 느끼지 못하겠다면 환불을 요청해 주세요. 이유를 불문하고 100% 환불해 드리겠습니다.

I think the biggest feature and advantage of Baek Gi-seon's lecture is that it doesn't just provide the right answer to the problem, but also teaches you how to find and choose a method to solve the problem. In most of Baek Gi-seon's lectures, the parts where he shows you the moments when he makes a mistake or encounters an unexpected problem, finds a method, and solves the problem through debugging without editing, made me feel like I was doing live coding with him, and it was good because I could see how he views the problem and solves it. When I first started developing, I only had a vague dream of becoming a Spring developer. I didn't know what kind of problem Spring technology was created to solve, what kind of value it provides to our developers, and how it became so popular. However, two years ago, I happened to come across Baek Gi-seon's YouTube channel, and from the first REST-API lecture at Inflearn to the current Effective Java lecture, I realized that technology is not everything when living as a developer, and I reflected on it, and I focused on learning the unchanging fundamental technology and knowledge that are the foundation of many technologies that change like Spring. Let me talk about the lecture atmosphere briefly. In the past, I felt that it was somewhat stiff and a little unfriendly, and I thought that there would be quite a few people who would be sensitive to this, but now I feel that the overall lecture atmosphere and lecture quality have greatly improved. It's the best. Lastly, after communicating with Baek Gi-seon through YouTube and Inflearn for two years, I got a job this year and am happily working at the company. I am truly grateful to Baek Gi-seon, who helped me establish my identity as a developer and realize how to study, and to Inflearn, who helped me easily access such a great lecture! I look forward to better lectures and better services in the future!!

It was good that the content of the book, which is less than 100 pages, was explained in detail with key points and perfect strategies in about 13 hours. After reading the book once and taking the lecture, I understood the lecture better, and even if I read the book several times on my own, if I don't have basic knowledge, I wouldn't understand it, so it was very helpful to understand it by dividing the explanation of the book and the keywords covered in the book. However, what was disappointing was that there were many lecture PPLs throughout the lecture, so there were times when I lost focus. There were many mentions of the Java series and design pattern lectures, and if there were many lecture references in each video (I understand and am familiar with the fact that these lectures are important as prior knowledge and reference content), I wonder if it would have been better to create a separate video explaining Gi-seon's existing related lectures related to this lecture, just like the Spring Framework Core Technology lecture, where the lecture introduction and instructor introduction were separated, and explain only the learning content in the lecture. I think it would be good for reviewing, learning, and referring to the lecture correlation. Despite the shortcomings, I will definitely watch the next lecture if it is released. I hope you continue to provide good lectures^^

I like Ki-seon's lecture style because it feels more like a real lecture, with scenes where he laughs and makes mistakes, rather than feeling stiff like other lectures. Even MS developers make mistakes like that, so I feel like they're not robots but people. 🤣🤣🤣 I've taken Ki-seon's lectures a lot, but this lecture is based on basic knowledge, so I don't think there's a more difficult lecture than this one (He promotes other lectures, but he reminds us of the content as a preview, so I think students can judge what's lacking by looking at the table of contents.) Since Effective Java is a translated book, it's not easy to understand, but it felt like he was translating it again, so I was able to approach it comfortably. (It's still difficult, though..) Unlike the lectures you've filmed in the past, he asks questions and answers more, so I think it gave me time to think more deeply. I really like this style!! If you didn't feel any changes until you finished it, you can get a 100% refund, so listen to it all. There's a reason Ki-seon is confident. !! p.s) When will the next part come out?

In some ways, I feel like I'm regressing because I've been using it the way I always used it, even though I need to know the characteristics of Java properly while working, so I came across Ki-seon's lecture while trying to study it again. I'm watching it along with design patterns and refactoring. There are many parts of Ki-seon's lecture that are related to the areas used in practice, and since he also provides necessary background information, I think it's very helpful for expanding my knowledge. And the best part is that it's not a set framework, but the process of solving problems that arise in real life is also a good experience. I tried Effective Java once before with a book, but I just progressed through it and couldn't properly digest it. When I read it in a book, there were a lot of things that were stiff and incomprehensible, but I think Ki-seon is filling in the gaps of knowledge that I couldn't access in the book. Is it just a feeling that the organization is getting better compared to the old YouTube videos? In the past, it was live coding, but it was difficult to concentrate, but these days, it seems that organizing knowledge by giving questions to think about while organizing in between is also helpful. It is difficult content, but if you follow it step by step, it will be very helpful. I am looking forward to the remaining 4 parts :)

Effective Java, which is considered a must-read for Java developers, was recommended in the translator's note, and I was always disappointed that the Effective Java YouTube lecture by Baek Ki-seon was only halfway through. As Baek Ki-seon continued to give lectures, I thought, "Wouldn't you make Effective Java into a lecture?" and when I heard that he was actually making it into a lecture, I bought it right away. I think that the combination of his previous experience of making a video introducing the contents of the book and his experience of consistently making lectures on Inflearn made for a better lecture. The questions that came up in the middle of the lecture made me think about what I was missing and what I was lacking, and it was good that he also conveyed things that developers should consider, not just the contents of the book. And it may not be related to this lecture, but it seems very helpful that when an error occurs in the source while recording a lecture, instead of editing the content and replaying it, you can also watch the process of solving the error. Although this lecture alone does not cover all the contents of the book, I think I have the opportunity to look at the book thoroughly. And in my case, I think I will have time to understand the parts covered in this lecture to some extent until the next lecture comes out. Baek Gi-seon's lectures/videos somehow seem to create passion. I always look forward to the next lecture and the one after that, and I will also relearn the contents of the previous lectures that Baek Gi-seon made until the next part comes out. Thank you for the great lecture. ^^

  There are likes and dislikes for the error correction part, so in the lectures I make recently, I try to edit and convey it neatly. Later, I can collect only the parts with errors and upload them to YouTube, but many people are sensitive about such parts in paid lectures. Thank you for your feedback.
