Question

I playing a sound file, and I create a new thread every time the playSoundFile() method is called. I just need to know how to pass the information from the method call into run() within the thread, so It can be used within.

        public void playSoundFile(File file) {//http://java.ittoolbox.com/groups/technical-functional/java-l/sound-in-an-application-90681
            new Thread(
                    new Runnable() {

                        public void run() {

                            try {
    //get an AudioInputStream
    //this input stream can't use the file passed to playSoundFile()
                                AudioInputStream ais = AudioSystem.getAudioInputStream(file);
                                ...
                                }

                            } catch (Exception e) {
                                e.printStackTrace();
                            }
                        }
                    }).start();

        }

Simply declare the variable to be final, then you can use it in your anonymous inner class:

public void playSoundFile(final File file) {
   ...
