"For programmers, if one day he stops learning, then his career will begin to die." This is not an alarmist rhetoric, but a big cow told me a few years ago.

In recent years, the salary of programmers has been increasing, which has led to more and more people engaged in the IT industry, and indirectly, the requirements of enterprises for developers have also become higher. To what extent can I be qualified to say that I am proficient in Java? Personally feel that at least the following needs to be done:

Expanding the breadth of knowledge, but also strengthening their technical depth.

Many people believe in "don't make wheels", a sentence that seems to be very cost-effective, but they don't know that this sentence has a premise, that is, "you have to know the internal structure of the wheel", otherwise it is self-paralysis. Next, you need to choose one or several aspects to study in depth and build your own core competitiveness.

A programmer with technical depth has a soul. And BAT is also willing to pay for the interesting soul. At this time, it is not only the salary level, but also the broad prospects for promotion and development.

Technological breakthroughs need to rely on the needs of business scenarios and their own deliberate planning and learning, both of which are indispensable. But the former is an opportunity, which is often not completely controlled by oneself. If there is no practical scene at work, the best way is to study and sort out systematically. Only when the standby will come, can you show your skills.

The editor here will share with you a holiday benefit. Many lecturers with 10+ years of Java development experience will teach you the architecture design of high concurrency, distributed, big data, and high availability systems. They will be integrated into a PDF. PDF will be explained from the following aspects

The first stage: foundation stage (Java foundation + grammar foundation + object-oriented concept, etc.)
The second stage: the entry stage (Web development + MySQL database, etc.)
The third stage: advanced stage (mastering the Java ecosystem + important tools + interviewers and SSMs investigated by the company)
The fourth stage: actual combat stage (hands-on actual combat + master project specific)
