Speaking of happen before, a lot of people know. However, because of the abstraction of the theory and the subtlety of semantics, the understanding of happen before often falls into the position of "nowhere near". This paper attempts to macro and multi-angle to analyze the many problems around happen before, so as to find out why we need
The most important capability of a product manager is not a skill, but "let the right thing happen one after another 」.

Preface
Landlord this title actually has a kind of death flavor, why, these three things can be divided into three articles to write, but, the landlord that these three things are highly relevant, should be in a knowledge point. Understand these things in a single study. To better understand the Java memory model and the volatile keyword and the HB principle.
The landlord is trying to tell the three questions in an article, and finally summarize. The hardware knowledge that must be reviewed befo
shared variables have the same effect as volatile modified variables when access is not super-frequent.
Volatile does not guarantee atomicity, this is not very clear, so it is easy to make mistakes.
Volatile can prohibit reordering.
So if we are sure that we can use volatile correctly, then it is a good usage scenario when we prohibit reordering, otherwise we don't need to use it again. Here are just a few examples of volatile usage scenarios, that is, when identifying bits (such a

This will happen in ten years, because people know it 60 years ago.
This was the case ten years ago, and today ten years later, there was no slight change, so there will still be a variety of things in 10 years, and open source will not save us, because people already know this 60 years ago.

As we all know, the structure (struct) is the value type, and the class (class) is the reference type. Now let's consider a question. If there is a reference type member in the structure, what will happen?Now we have a structure oneline. Let's first introduce its features. It can be regarded as a line of string, but it also consists of several parts. Let me take an example: "ABCD", in some applications, I may need to know which elements the string con
