        }

    }
    
}

 

 

第二种方式：带面板，可控制的

        setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
        setVisible(true);

    }

    public static void main(String[] args) {
        new MusicDemo();

    }


    public void run() {

            URI uri = file.toURI();//创建一个URI对象
            URL url = uri.toURL();//创建一个URL对象
            clip = Applet.newAudioClip(url);//创建一个音频对象
        } catch (MalformedURLException e) {
            e.printStackTrace();
        }

    }


    @Override
    public void itemStateChanged(ItemEvent e) {
        System.out.println("itemStateChanged方法进来了");
        str = musicCombox.getSelectedItem().toString();
        System.out.println("----------str:"+str);
        if(!(thead.isAlive())){
            thead = new Thread(this);
        }
        try{
            thead.start();
        }catch(Exception ee){

        }
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        System.out.println("actionPerformed方法进来了");
        if(e.getSource() == btn_play){
            clip.play();
        }else if(e.getSource() == btn_stop){
            clip.stop();
        }else if(e.getSource() == btn_loop){
            clip.loop();
        }
    }

}
