I don’t know if you have this feeling in the interview: interviewers usually have a comprehensive understanding of the interviewer’s knowledge structure in just two hours. If the interviewer is procrastinated and can’t directly address the nature of the question, it’s difficult Fully express yourself, and ultimately affect the interview results.
In response to this situation, this hand-written note on Java core knowledge by Ali architects came into being! This note does not procrastinate when explaining the knowledge points, and strives to be concise. It introduces in detail the core knowledge points that Java programmers are often asked in interviews.
There are nine parts in this note, covering one year of Java development to a summary of the interview knowledge points at the Java architect level. The author promises: This note is 100% free! Because there are too many knowledge points in this note, the editor can't show it all completely. The free way to obtain this note is at the end of the article!
