First of all, judging from the talent training objectives of most Java training courses, it is mainly to train junior programmers in the industry to achieve the development ability required for junior development positions, so programmers who have just stepped out of Java training courses are often junior programmers (assistant programmers). Due to the mature JavaWeb development technology system and the great demand for talents, many Java development classes use the Web technology system to set courses at present. Graduates often have certain Web development ability, but different people have different sensitivity to technology and often have great differences in development ability.

Program development itself requires more scenes. Whether programmers can continuously improve their posts in the future is related to many factors, including their own knowledge structure, development environment, industry and so on. Therefore, programmers who come out of the training class will have more room for growth in the future.

Judging from the current technical development trend of IT (Internet) industry, Java programmers should consider developing in the direction of big data in order to obtain higher post added value in the future. At present, the demand for talents in the field of big data development is still relatively large. With the application of big data platform, the number of big data application development jobs will gradually increase. Although the knowledge of big data development is relatively large, many developments based on big data platforms are not too difficult to learn, and beginners can fully master them through a systematic learning process.

Finally, in the process of learning Java, we must pay attention to appropriately expanding our knowledge. For beginners with weak foundation, we should focus on strengthening the learning of operating system and database knowledge. If we want to take the R&D route in the future, we should also focus on learning the knowledge of algorithm design.

I have been engaged in the Internet industry for many years, and I am currently a graduate student in computer science. My main research direction focuses on big data and artificial intelligence. I will write some articles on internet technology one after another, and interested friends can pay attention to me. I believe I will gain something.
