JMSL Tutorial: Instruments and Interpreters

Here, we've declared a subclass of Instrument called PrintingInstrument, which overrides play() as described in the previous tutorial. We've also built a four dimensional MusicShape and plugged one of these PrintingInstruments into the MusicShape's Instrument. Here's how:

        
        myMusicShape.setInstrument(new PrintingInstrument());

The results are shown in the screenshot below. Note that the duration between printed lines is the first element in the array (ie. 1 sec, 1 sec, 0.5 sec, etc).
