Java multi-thread (4) thread pool and java multi-thread pool A good software does not randomly create and destroy threads, because it takes a lot of CPU time and requires a lot of interaction with the memory. Therefore, JDK 5 proposes to use the thread pool so that programmers can focus more on the business logic and w

Linux thread control Thread separation, linux threadThread Concept A thread, sometimes called a Lightweight Process (LWP), is the smallest unit of the program execution flow. A thread is a single sequential control flow in a program. A relatively independent and schedulable execution unit in a process is the basic uni

Summary of this chapter: 1: Termination status and non-termination status 2: differences between autoresetevent and manualresetevent 3: waithandle. waitone (), etc. 1: Termination status and non-termination status First, let's talk about the termination and non-termination states of the thread. Both autoresetevent and manualresetevent constructors have bool variables to indicate the termination and non-termination statuses of the
