A Java NIO Pipe is a one-way data connection between two threads. A <code>Pipe</code> has a source channel and a sink channel. You write data to the sink channel. This data can then be read from the source channel.
Here is an illustration of the <code>Pipe</code> principle:

You open a <code>Pipe</code> by calling the <code>Pipe.open()</code> method. Here is how that looks:
To write to a <code>Pipe</code> you need to access the sink channel. Here is how that is done:
You write to a <code>SinkChannel</code> by calling it's <code>write()</code> method, like this:
To read from a <code>Pipe</code> you need to access the source channel. Here is how that is done:
To read from the source channel you call its <code>read()</code> method like this:
The <code>int</code> returned by the <code>read()</code> method tells how many bytes were read into the buffer.
