Download files with Java
In my many home-brew projects I have found myself using this next piece of code to download files or web pages from the net.
It is very easy and I think it should always be in your reach.
public static void download(String downloadPath, String localFilePath) {
OutputStream out = null;
URLConnection conn = null;
InputStream in = null;
try {
//Connecting to site
URL url = new URL(downloadPath);
conn = url.openConnection();
in = conn.getInputStream();
out = new BufferedOutputStream(new FileOutputStream(localFilePath));
byte[] buffer = new byte[1024];
int numRead;
long numWritten = 0;
//Reading the file into buffer
while ((numRead = in.read(buffer)) != -1) {
out.write(buffer, 0, numRead);
numWritten += numRead;
}
} catch (Exception exception) {
exception.printStackTrace();
} finally {
try {
if (in != null) {
in.close();
}
if (out != null) {
out.close();
}
} catch (IOException ioe) {
}
}
}
As you can see, really simple and useful.
I’ll probably use it in my next posts.
