i working classmates on game, have programmed quite music until now. music.java class posted below.
we have problem stopping our sound, need way stop clip playing can start clip, way can shift through music during our game (like when start game, song should different main menu). can me problem?
even if can destroy object make new one, if that's possibility, willing that, not have clue how this. rather have possibility stop current clip file, , replace new one.

in guicontroller, make new music object, through method playsiren give songname, , automatically runs.
look dataline.stop() method. clip implements dataline.
e.g. clipcontrol.java
import java.awt.event.*; import javax.swing.*; import javax.sound.sampled.*; import java.net.url; class clipcontrol { public static void main(string[] args) throws exception { url url = new url("http://pscode.org/media/leftright.wav"); audioinputstream ais = audiosystem.getaudioinputstream(url); final clip clip = audiosystem.getclip(); clip.open( ais ); runnable r = new runnable() { public void run() { final jtogglebutton startstop = new jtogglebutton("stop"); startstop.addactionlistener( new actionlistener() { public void actionperformed(actionevent ae) { if (startstop.isselected()) { clip.stop(); startstop.settext("start"); } else { clip.loop(-1); clip.start(); startstop.settext("stop"); } } } ); clip.loop(-1); joptionpane.showmessagedialog(null, startstop); } }; swingutilities.invokelater(r); } }
