Run the program

I encourage you to copy the code from Listing 9 and Listing 10 . Retrieve the necessary source code for the other three classes from the module titled Jbs2010-Your First Sound Program . Compile the code and execute it. Experiment with the code,making changes, and observing the results of your changes. Make certain that you can explain why your changes behave as they do.

Miscellaneous

This section contains a variety of miscellaneous information.

Listing 9 . The class named MusicComposer07.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
