problem:

I graduated with a year of working experience in java. I am currently planning to leave, but I feel that I have not learned anything this year. I am afraid that I will not have enough knowledge to pass the interview and ask for advice~

In fact, what fans describe is a relatively common phenomenon, that is, after working for a year, they feel that they still don’t know anything. This is actually quite normal. The reason is that the things we commonly use in our work are basically encapsulated in Java. We usually write some business code, which means logic such as if else. For better students, encapsulate if else into a piece. Cite the mapping relationship of class + annotation. But this knowledge is often not enough in interviews. IT has a saying: Interview makes rockets, work screws . After all, every company hopes to recruit a player who makes rockets. What if he needs to do it?

Returning to the question of fans, one year of work experience for fans is not very recommended for job-hopping . They have been hiring recently. Stability is also very important in interviews. Three years are generally considered a stable performance . If you think that this company is really not suitable for you after thinking about it, then you really need to prepare for the interview, because the interview questions are often biased towards the bottom of the technology, architectural thinking, and difficult problem analysis. For example, the interpretation of the common hashmap source code. In practice, we use hashmap, but we rarely read the source code, let alone familiar with the expansion mechanism and put process. Or if we use redis, we may know more about clients such as jedis and redission. We rarely look at the underlying data structure of redis, communication protocol and so on. If you want to break through the java interview in a short time, I can share the common Java interview questions I summarized before, which can save some time. As the content is a bit too much, it is organized into PDF;

The document is divided into nine parts here:

Computer Basics
