1)loader.start() 앞뒤로 try catch를 안넣으면 오류가 나는데 이유가 뭘까요? 나머지는 다 똑같이 했습니다ㅜ

public class Browser implements OnDownloadListener {
	
	public void imgClick() {
		Downloader loader = new Downloader(this);
		try {
			loader.start();
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	@Override
	public void onDownFinish() {
		System.out.println("Browser : onDownFinish()");
	}

	@Override
	public void onDownFailed() {
		
	}
}
