what is stream in java

low IO efficiency, impact performance, but rebound processing. When throughput increases, there is a coup: the thread pool. Use thread pooling to manage threads, avoid frequent creation, and eliminate the overhead of threading. However, its underlying use is still synchronous blocking IO, often referred to as the "pseudo-asynchronous IO Model", is really a palli
