[Bluej-discuss] Fix to simplesound project, chapter 11

[Michael Kölling]

Sorry for the late reply - I think this was left unanswered so far...


Yes, you are absolutely right. The first version (in our code) is  
system dependant, and will work correctly on some systems and not on  
others. The second version is correct. (My students discovered that  
last year as well...)

Thanks for the fix - I'll make sure that it goes into the next  
edition of the book.
