thread pool guarantees that the order in which all tasks are executed is performed in the order in which the tasks are submitted. Newfixedthreadpool: Creates a fixed-size thread pool. Each time a task is committed, a thread is created until the thread reaches the maximum size of the threads pool. Once the maximum size of the thread pool is reached, the thread pool will be replenished with a new thread if it ends up executing an exception. Newcachedthreadpool: Creates a cacheable thread

logical error in the subordinate business.Synchronous operationConcurrent operation also need to maintain the consistency of data, more or less involves synchronous operation. Proper use of atomic operations and proper use of exclusive and read-write locks is also a big challenge.Coordination and communication between threads, especially state synchronization, are more difficult. We see the implementation of thread pool threadpoolexecutor in order to solve the execution state of various threads
