Oracle Docs on Capturing Audio in Java:

http://docs.oracle.com/javase/tutorial/sound/capturing.html

As discussed in Overview of the Sampled Package, a typical audio-input system in an implementation of the Java Sound API consists of:

An input port, such as a microphone port or a line-in port, which feeds its incoming audio data into: A mixer, which places the input data in: One or more target data lines, from which an application can retrieve the data.

(Emphasis Mine)

Also see: Java (J2SE) DTMF tone detection

I think usually this is done in hardware, so you may end up writing code yourself to analyze the audio you've captured.
