example

The MIDI sound examples' process never terminates, so after you run it, you don't get your command-line back. This is because the Sequencer starts a separate thread (we haven't gotten to the threads chapter yet, so don't worry about it at this point), and it keeps it running *even after your main method completes*. For now, think of it as almost like a separate program being launched -- so that even when your initial program (the one that starts with main()) returns, that *other* program, the one running the Sequencer, is still running. For now, we'll add two things at the end to close it down: Instead of: player.start(); } catch (Exception ex) { ... } Insert the following lines between player.start() and the catch block: Thread.sleep(1000 * 2); // inserts a pause to give the sound a chance to play player.close(); // closes the sequencer System.exit(0); // quits the Java application So... this is what it should look like now: player.start(); Thread.sleep(1000 * 2); // new player.close(); // new System.exit(0); // new } catch (Exception ex) { // everything else... =============
