Java multithreading: blocking queues
Blocking queues are often used in the scenario of producers and consumers. Producers are threads that add elements to the queue, and consumers are threads that take elements from the queue. A blocking queue is a container where producers store elements, and consumers only get elements from the UTF-8...

ArrayList is not thread safe
new ArrayList() will create an Object array with a capacity of 10. Each expansion of ArrayList is half of the original (oldcapacity + (oldcapacity > > 1)). ArrayList is thread unsafe.

Multithreading ThreadLocal -- boy next door ♂
1. Introduction What is it ThreadLocal provides thread local variables. These variables are different from normal variables, because each thread has its own independently initialized variable copy when accessing the ThreadLocal instance (through its get or set method). A ThreadLocal instance isUTF-8...

Java Concurrent thread locking mechanism
Why thread locks? Multiple threads will rob resources, so it is possible that one thread may be robbed of resources by another thread halfway through execution, which will cause thread insecurity. In order to ensure thread safety, we can use thread lock to solve this problem. For example, the UTF-8...
