- A question asked in almost all Java interviews: talk about the difference between ArrayList and LinkedList
- The data structure of Java is the focus of the interview. Anyone who has participated in a Java interview must have some experience. When interviewers ask such questions, they often want to check whether you have studied the underlying structures of commonly used data types in Java, rather than simply staying at the level of "knowing how to use".

- The interviewer asks you: Do you know what an ABA problem is?
- This issue is about the analysis of a classic ABA problem in the CAS field. I don’t know if you have encountered it in actual work, but this is the focus of the concurrency knowledge test in the interview. If you haven't come across this kind of problem, my suggestion is to run the above code yourself.

- Real interview question: Please talk about the CAS mechanism in concurrency
- In the program, I created 100 threads, and each thread accumulated 10,000 operations on the shared variable inc. If it is executed synchronously, the final value of inc should be 1,000,000, but we know that in multi-threading, the program is concurrent executed, that is to say, different threads may read the same value from the main memory at the same time.

For example, if the current object's lock has been obtained by one of the threads, other threads need to wait in this lock pool. When the previous thread releases the synchronization lock, the threads in the lock pool will compete. Synchronization lock, when a thread obtains it, it will enter the ready queue to wait for CPU resource allocation.
