<Java 核心技术 卷2 > 中的一句话的如何理解

fangnoodles

Both the read and write methods block until the bytes are actually read or written. This means that if the stream cannot immediately be accessed (usually because of a busy network connection), the current thread blocks. This gives other threads the chance to do useful work while the method is waiting for the stream to again become available.

请问, 黑体的这句话如何理解? 它体现了 Java流技术的哪些特性?

感觉 应该是    读写方法在bytes流没有真正读取之前一直是阻塞的  。 感觉应该有java 线程调度的让步 和 线程阻塞 。

write和read会因为没有读到字节流而阻塞   线程阻塞
