我在java中有一个方法可以从网上下载文件，但是通过java代码下载比使用任何浏览器下载要慢。
我的代码如下，
public void downloadFile(String downloadURL) {
System.out.println("Starting file download .....");
BufferedInputStream in = null;
FileOutputStream fout = null;
try {
URL u = new URL(downloadURL);
HttpURLConnection uc = (HttpURLConnection) u.openConnection();
String fileName = uc.getHeaderField("Content-Disposition");
fileName = YouTubeDownloader.parseResponse(fileName, "filename=\"", "\"");
System.out.println(fileName);
if (uc.getHeaderField("Content-Length") == null) {
System.out.println("File Length zero!!!!");
}
float fileSize = Float.parseFloat(uc.getHeaderField("Content-Length"));
in = new BufferedInputStream(uc.getInputStream());
System.out.println("File size : " + fileSize);
fout = new FileOutputStream("c:\\Dinesh\\" + fileName);
byte data[] = new byte[1024];
int count = 0;
int downloaded = 0;
while ((count = in.read(data, 0, 1024)) != -1) {
downloaded += count;
int downloadPercentage = (int) ((downloaded / fileSize) * 100);
System.out.println(downloadPercentage);
fout.write(data, 0, count);
}
System.out.println("File download completed.....");
} catch (Exception e) {
System.out.println(e);
}
}
下载速度太慢是因为缓冲区较小吗？
我可以增加缓冲区大小或如何优化缓冲区以降低下载速度吗？
我需要修改哪些内容？
提前致谢。
