In the Java multithreaded application, the queue usage is very high, most of the production consumption model's preferred data structure is the queue (FIFO). Java provides a thread-safe queue that can be divided into blocking queues and non-blocking

Hash table This data structure presumably most people are not unfamiliar, and in many places will use hash tables to improve the search efficiency. There is a method in the object class in Java:public native int hashcode ();According to the

Thread's queueIn Python, queues are the most common form of exchanging data between threads. The queue module is a module that provides queued operations, although it's easy to use, but if you're not careful, there are some surprises.create a '

The comparison between HashMap and Hashtable is a common problem in the Java interview to test whether the programmer can use the collection class correctly and whether it can be used in a variety of ways to solve problems. The work of HashMap, the

Java NiO uses the operating system layer to support non-blocking Io. It is no longer stream-based data transmission, but buffer-based data transmission. NIO's biggest changes include non-blocking Io, which can reduce the number of threads; buffer
