버튼초기화 부분과 컴포넌트들 추가 부분의 소스를 작성하지 못하고 있습니다.

계속 오류만 생기고....제발 아시는 분들 답변좀 주세요~~급해요ㅠ.ㅠ

버튼들을초기화한다.

.....

/ 타임바(mediaTime) 초기화

mediaTime = new JSlider(JSlider.HORIZONTAL);

mediaTime.setPaintTicks(false); / 눈금을표시하지않는다.

mediaTime.setMaximum((int)(control.getDuration()/1000000000L));

mediaTime.setValue(0);

/ 사용자의타임바변경을받는다.

mediaTime.addChangeListener(new ChangeListener(){

public void stateChanged(ChangeEvent e){

int changedValue = mediaTime.getValue();

int oldValue = (int)(control.getMediaTime()/1000000000L);

if(!(changedValue oldValue -2 && changedValue oldValue + 2)){

control.setMediaTime((long)(changedValue*1000000000L));

}

}

});

/ 볼륨조절초기화

volumn = new JSlider(JSlider.VERTICAL);

volumn.setPaintTicks(false);

volumn.setMaximum(10);

volumn.setValue((int)(control.getGainControl().getLevel()*10));

volumn.setPreferredSize(new Dimension(30, 40));

/ 사용자의볼륨조절을받는다.

volumn.addChangeListener(new ChangeListener(){

public void stateChanged(ChangeEvent e){

int changedValue = volumn.getValue();

control.setGain(((float)changedValue)/10);

}

});

.......

컴포넌트들추가

.......

}

public void volumnChanged(float changedVolumn){---(3)

volumn.setValue((int)(changedVolumn*10));

}

public void mediaTimeChanged(long mediaTime, long duration){ ----(4)

int dura = (int)(duration/1000000000L);

int mTime = (int)(mediaTime/1000000000L);

mediaTime.setMaximum(dura);

mediaTime.setValue(mTime);

}

public void actionPerformed(ActionEvent e){ ----(5)

String actionCommand = e.getActionCommand();

if (actionCommand.equals(PLAY_BTN_ACTION_COMMAND)) {

control.play();

}else if(actionCommand.equals(STOP_BTN_ACTION_COMMAND)) {
