Java ThreadPoolExecutor.shutdown() is a method in the Java ThreadPoolExecutor class that initiates an orderly shutdown of the executor, in which previously submitted tasks are executed, but no new tasks will be accepted. It is typically used when no more tasks need to be processed and the thread pool should be terminated. Introduced in Java 2004 with Java 5, shutdown() helps manage thread resources effectively in concurrent Java applications.
