JAVA learning is a long way (reposted)

I started learning Java before Java 1.0 was officially launched. After so many years, I have not stopped learning Java. I read the original book, studied the original code, and wrote the program. I thought that I had taken a solid step, and I did not expect to go to heaven. An old-fashioned way of learning like me is clearly contrary to the current fast food theory. From the comments of many readers and the responses of students, I found that most people have similar learning experience in Java: because companies need to use Java for server planning, so I was eager to learn the Java language, and then began to use the J2EE API and started to write the program. As a result, programmers cannot master the essence of object orientation, understand the internal operation mechanism of the Java language, and understand the overall consistency of APIs.
Of course, we cannot blame programmers for this. After all, software technology changes too fast. It is impossible for a company to give programmers enough training to start planning. Programmers are assigned to use the technology at once. They have not yet understood what the technology is. They are also assigned to use the B technology, and they are all learned and used by means of sewing and makeup, every time it seems like a new start, let's talk about the accumulation of technical energy.
I'm glad that I don't have such troubles. Because I was from the Information Engineering Department (and I have always taken classes seriously in college), it is not difficult for me to learn new technologies because I have a solid theoretical foundation. When I was in college, many people around me looked down on the so-called "schools" of data structures, programming languages, and operating systems, and thought these courses were not practical at all. They thought that what they learned from external companies could not be used. "as long as Visual Basic and database are used 」. This kind of biased mentality may make them suffer in the era of knowledge economy.
Another group of students looked down upon the design work. They told me that people who write programs like me will enter the community in the future, "they are not under the feet of management personnel 」. Therefore, they are very light on learning science and technology courses, and even some people are very keen on "success". They think that this is a fast way to success, but they leave their school class blank. I can't believe someone put the horse above the horse.
The people in the first category are too short-sighted and close-benefit, while those in the latter category are too ambitious. I have never understood why these people think like this, perhaps because of the social environment. I am glad that I have not been corrupted by the Big Dyeing cylinder of the society (it is best not to use it in my life ). I don't think my learning method is a model, but it is still quite a little progress along the way. Many readers have asked me about my learning process. Although my personal learning method does not apply to everyone, there may be some reference values (especially for young students who are interested in the information industry ), I would like to briefly describe this article.
I have always used Deep learning (also known as Bottom-Up and Deep-First. For example, when I was learning A technology, I learned half of the basics of B technology. I would go to the bookstore to find one or two books about B technology, and then put A Aside first, start reading the book of skill B. Even when I see unfamiliar sentence structures in technical books, I will find an English grammar book that I have read in detail. This kind of deep learning method is suitable for students in the age of comprehensive self-improvement, but not for the industry. Imagine how the boss has delayed the development of the ERP system. How can you study the English grammar in the original J2EE book. The advantage of deep learning is that learning is solid, but sometimes it may deviate from the topic too much. I once discovered that I was going to learn a software technology. After several times, I was able to see Lao Tzu's morality.
