A summary of 1,300 Java interview questions in 2023. Get an offer from a big company directly after completing the exam!

LZ believes that the best way to learn Java interviews and advanced skills is to answer questions + blog + books + summary . The first three LZ will vividly display in this article. As for the summary, it is up to you personally. In fact, you will know it later. I found that the interview is not difficult. The second thing is whether you think about it during the process of answering the questions. Answering the questions is only the second. This is another level. I will not mention it here for now and will talk about it later.

Nowadays, the phenomenon of involution among large manufacturers is rampant, and the tradition of 996 is still rampant. But no programmer can resist the temptation of high-paying positions at major Internet companies. In particular, I also have an old friend who has worked for Alibaba for more than 7 years. He keeps painting the beautiful scenery described by Dachang in my mind, which makes me always have the dream of joining Dachang for gold plating.

So in order to fulfill my dream of entering a big factory this time, I specially asked my old friend to sort out this "Java Senior Programmer Interview Essence Questions" a week ago. It also helped me catch up in the final period of the gold, three and silver four. It’s the last train of the job-hopping season and I successfully joined JD.com!

Although the golden period of job-hopping for gold, three, silver and four has passed, if you still want to change jobs and join a big factory, the golden period of gold, nine and silver ten will also be a good opportunity. Use these few months to hoard your technical skills and brush up on the interview questions. Also make complete preparations for job-hopping.

Now I am sharing this document with everyone who sees it, so as to save everyone some time in searching for information, browsing literature, and answering questions.
