停止 Java 小程序中文件的下载

我想知道停止下载文件的最优雅和最佳的方法是什么。我有一个简单的小程序，应该从我网站上的用户帐户下载请求的文件。

我想为我的用户提供随时停止下载的可能性。我的代码的简单版本：

InputStream is = null;
FileOutputStream os = null;
os = new FileOutputStream(...);
URL u = new URL(...);
URLConnection uc = u.openConnection();
is = uc.getInputStream();
final byte[] buf = new byte[1024];
for(int count = is.read(buf);count != -1;count = is.read(buf)) {
    os.write(buf, 0, count);
}

我唯一的想法是定义新变量，例如 MyStop，将其设为 false 并放入我的循环指令中：

if(MyStop == true) { break; }

当用户单击“停止”按钮时，MyStop 将更改为 true。

这就是我的想法，但我很确定有更好的解决方案。

I wonder what is the most elegant and optimal way to stop downloading a file. I have a simple applet which is supposed to download requested files from user account at my website.

I would like to offer my users possibility to stop download at any moment. Simplet version of my code:

InputStream is = null;
FileOutputStream os = null;
os = new FileOutputStream(...);
URL u = new URL(...);
URLConnection uc = u.openConnection();
is = uc.getInputStream();
final byte[] buf = new byte[1024];
for(int count = is.read(buf);count != -1;count = is.read(buf)) {
    os.write(buf, 0, count);
}

My only idea is to define new variable e.g. MyStop, make it false and put in my loop instructions:
