| Listing 6 . Populate the audio data array. |
|---|
melody[cnt] = byteHigh;melody[cnt + 1] = byteLow;}//end for loopreturn melody;}//end method getMelody
//-------------------------------------------------------------------------//}//end class SquareWave |
Listing 6 also signals the end of the for loop and returns the populated array's referenceafter the loop terminates.
Finally, Listing 6 signals the end of the getMelody method and the end of the SquareWave class.
I encourage you to copy the code from Listing 7 through Listing 11 . 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.
This section contains a variety of miscellaneous information.
