[Java] Problem with File I/O

 

Hi guys,

I have a problem with my program. I tried to make a simple program to download pdf file from internet. First, I tried to use it for downloading text and html file, it works well. but, it didn't work with pdf file. the program could produce output file, but it can't be opened.

Here is the code snippet:

java.io.BufferedInputStream in = new java.io.BufferedInputStream(new java.net.URL("http://www.digilife.be/quickreferences/QRC/JAVA%20Quick%20Reference.pdf").openStream());
java.io.FileOutputStream fos = new java.io.FileOutputStream("output.pdf");
java.io.BufferedOutputStream bout = new BufferedOutputStream(fos,1024);
byte data[] = new byte[1024];
while(in.read(data,0,1024)>=0)
{
bout.write(data);
}
bout.close();
in.close();

Anyone could give me the clue? BTW, is there any website that provide free java library, especially one that support file operation (download, upload, etc)?

Thanks in advance.
