Although I learned a lot, I was quite confused. I knew a little about all aspects of technology, but I didn’t have enough depth. In the interview, if the interviewer asked me some questions that I hadn’t heard of, I would be overwhelmed instantly.
I found that what I lacked was systematic knowledge and systematic learning. From then on, I gradually began to think about why Java is still so popular, how to learn Java technology, and my future development direction. Since Sun released Java in 1995, it seems that Java has never left the radar of software engineers, and the number of developers entering the Java ecosystem grows every year. It is suggested that you can go to a good training class for systematic learning. Chengdu Langwo is very good. Systematic learning, from zero-based entry to enterprise-level development.
According to incomplete statistics, there are 2.5 billion electronic devices running Java in the world, more than 4.5 million Java developers active in the Web application and Android markets, 708 million mobile phones running Java applications, 1 billion smart cards and 1 billion PCs. More and more enterprises are using Java to increase productivity. I think this is probably why Java has become the number one development language in China and abroad.
