Preface
At present, the vast majority of Java programmers are in the stage of adding, deleting, modifying and investigating, but after this stage, they should consider the next level of breakthrough. They can't be a lifetime crud...
Judging from the current development trend and employment situation of the IT industry, the market has no shortage of primary development, and it is quite rare for middle and senior development talents. The job of programming is like going back against the current. Technology is constantly being updated. You can imagine that the company can't survive the impact of the epidemic. You are the one who was unfortunately shot. How should you find a job in the future? Does your work experience match the current recruitment requirements of the industry?
When your body and mind have formed the habit of fishing and swimming, it is very difficult to change quickly in the short term. All you can do is to make progress gradually. The next two months are about to usher in the peak of job-hopping. It is better to prepare as soon as possible. Take a little time every day to study and get a satisfactory job in Jinjiuyinshi.
So how to advance as a Java developer and change the status quo? In fact, there are a lot of searches for this kind of questions on Zhihu, and there are many answers that are very good, for your reference and study, but after all, it is still hard work + persistent study.
There are few good study notes in the market. It took me a long time to summarize this "Advanced Knowledge System for Java Programmers" to help you progress systematically and efficiently. Learning, not scattered and inefficient reading.
