如何在Java中实现Go的无缓冲通道？

Question

Go offers both unbuffered and buffered channels for communication among goroutines (threads). It is straightforward to implement buffered channels as bounded buffers in Java.

Go's unbuffered channels require one goroutine to be sending when the other goroutine is receiving. Can anyone explain to me how to implement that in Java?

In Java you can use a SynchronousQueue, the source for Java 8 is here
