synchronized meaning

A keyword in the Java language that, when used to modify a method or a block of code, ensures that at most one thread at the same time executes that segment of code. First, when two concurrent threads access the synchronized (this) synchronized

The most important one is:Synchronized is used for implicit locks of objects. Note that it is an object! For example, this example does not have any business meaning, just to illustrate the basic usage of synchronized:Java codeClass MyClass

For example, an object is like a big house, and the door is always open. There are many rooms in the house (that is, the method ). These rooms are locked (Synchronized Method) and not locked (normal method ). There is a key at the door of the room,

For example, an object is like a big house, and the door is always open. There are many rooms in the house (that is, the method ). These rooms are locked (Synchronized Method) and cannot matchLocks (common method ). There is a key at the door of the

Synchronized usage in Java (zz)   For example, an object is like a big house, and the door is always open. There are many rooms in the house (that is, the method ). These rooms are locked (Synchronized Method) and not locked (normal method )

Recently in a monitoring system, the system mainly includes real-time data analysis and storage of two parts, due to the high concurrency, so the inevitable use of some concurrency knowledge. To implement these requirements, the background uses a

In concurrent programming, we typically encounter the following three problems: atomicity, visibility, order. Let's take a look at these three concepts in detail:1. atomicityAtomicity: That is, one operation or multiple operations are either
