I remember when I was in college, Java wasn’t as popular as it is today. On the Internet, learning Java will be generally despised by C++, because they learn C++ friends will have a natural superiority, think that Java does not have to manage its own memory, nothing you do, the JVM does it for you, “idiot” can learn! I was one of those idiots who asked myself: Is Java really that easy?

After so many years, MY understanding of Java is getting deeper and deeper. I have come into contact with many programming languages in my work, including the very old Delphi and the latest Go. Among so many programming languages, I still love Java and realize that any language is not as simple as you think!

In my circle, there are often small friends who ask why they can’t answer the knowledge points they originally understand in the interview.

The answer I give you is, do you really understand?

If you can’t answer it, it means that you really haven’t understood a certain knowledge point thoroughly. In the technical interview of large Internet companies, the interviewer will start from a small knowledge point and continue to dig deep, so as to know the depth and breadth of your whole knowledge system.

Here are some of our original analysis articles on interview questions, hoping to inspire you in your job interview.
