Java Thread Pool Execution Process Guide
The execution process of a Java ThreadPool is as follows:
- Create a thread pool: Start by creating a thread pool, which can be done using static methods from the Executors class, such as Executors.newFixedThreadPool().
- Submit a task: then submit the task to the thread pool, you can submit the task through the execute() or submit() method of the thread pool.
- ThreadPool executes tasks: The ThreadPool will execute tasks based on the specific type and configuration of the ThreadPool, usually by using scheduling threads to execute tasks.
- Task execution completed: After a task has been executed, the thread will return to the thread pool and wait for the scheduling of the next task.
- Close the thread pool: When the thread pool is no longer needed, the shutdown() method should be called to close the thread pool and release resources.
In general, the workflow of a thread pool is to create the thread pool, submit tasks, execute tasks in the thread pool, complete task execution, and finally close the thread pool.
