Here comes the most powerful synchronized tutorial in history. I suggest collecting it

Why locks are needed: Because there are critical resources, the so-called critical resources means that there can only be one resource operating in the unified time, such as a printer. If multiple print tasks are executed at the same time, it will be disordered. Critical resources are resources accessed by only one process or thread at the sam ...

locks of Java Concurrent Programming

Locks are used to control how multiple threads access shared resources. Generally speaking, a Lock can prevent multiple threads from accessing shared resources at the same time (but some locks can allow multiple threads to access shared resources concurrently, such as read-write locks). Before the emergence of the Lock interface, Java progra ...
