### Question:
Timeline { public void movePlaybackPosition(int position, OnCueListener listener) { if (mModCount != mLastUpdateModCount) { updateCueList(); } while (mListIterator.hasNext()) { Cue cue = mListIterator.next(); mListPosition++; if (cue.getTime() <= position) { listener.onCue(cue); } else { mListIterator.previous(); mListPosition--; break; } } } Timeline(); synchronized void addCue(Cue cue); synchronized boolean removeCue(Cue cue); void setPlaybackPosition(int position); void movePlaybackPosition(int position, OnCueListener listener); int count(); synchronized void reset();  }### Answer:
@Test public void movePlaybackPositionOnEmptyList() { Timeline t = new Timeline(); t.movePlaybackPosition(1000, new OnCueListener()); }
