1. Thread in process In the figure above: On the left is a process with a single thread, which has its own complete set of resources. On the right is a process with two threads. Threads share resources in the process with each other. It can be seen that thread is a lightweight process, which provides an efficient way of task processing. ...

Thread pool Personal blog: www.xiaobeigua.icu 1.2} thread pool Thread pool is a common way to use threads effectively. A certain number of working threads can be created in the thread pool in advance. The client code directly submits tasks to the thread pool as an object. The thread pool caches these tasks in the work queue. The working t ...

join() method in multithreaded Thread As we all know, the join() method adds thread B to thread A, and A blocks and waits for B to finish running. However, if you call multiple joins and add multiple sub threads in A at A time, will it become A single thread mode (sequential execution). Let's take A look at the specific analysis of the join me ...

Concept: Concurrency and parallelism Parallelism: multiple instructions are executed simultaneously on multiple CPUs at the same time Convenient memory: five people (multiple CPUs) play black games, one mobile phone, and five people execute at the same time For parallel Concurrency: at the same time, multiple instructions are executed altern ...

Singleton mode Singleton mode is a design mode,    the so-called design patterns, like chess scores, have produced corresponding solutions for some specific scenarios. For example:   the DataSource we created when learning JDBC should be a singleton.   in addition, there are some classes responsible for loading data in ...

ThreadLocal allows shared variables. In a multi-threaded environment, each thread maintains a copy of the shared variables and operates thread local variables independently of each other to avoid thread safety problems.   Looper in Android uses ThreadLocal to save looper objects of multiple threads. The relationship among Thread, ThreadL ...
