![How to Download. Zip File from Url Using Java [Duplicate]](https://docuprint.cloud68.co/uploads/how-to-download-zip-file-from-url_1200.jpg)
guys! I have a problem! I'm trying to download a .zip (size is 150 mb) file from Internet using this code:
public void downloadBuild(String srcURL, String destPath, int bufferSize, JTextArea debugConsole) throws FileNotFoundException, IOException {
debugConsole.append(String.format("**********Start process downloading file. URL: %s**********\n", srcURL));
try {
URL url = new URL(srcURL);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
httpConn.setRequestMethod("POST");
httpConn.connect();
in = httpConn.getInputStream();
out = new FileOutputStream(destPath);
byte buffer[] = new byte[bufferSize];
int c = 0;
while ((c = in.read(buffer)) > 0) {
out.write(buffer, 0, c);
}
out.flush();
debugConsole.append(String.format("**********File. has been dowloaded: Save path is: %s********** \n", destPath));
} catch (IOException e) {
debugConsole.append(String.format("**********Error! File was not downloaded. Detail: %s********** \n", e.toString()));
} finally {
try {
if (out != null) {
out.close();
}
if (in != null) {
in.close();
}
} catch (IOException ex) {
}
}
}
but the file is not completely downloaded. (only 4000 bytes). What am I doing wrong?

FileOutputStream("example.zip").getChannel().transferFrom(Channels.newChannel(new URL("").openStream()), 0, Long.MAX_VALUE);
Simple one-liner. For more info, read here
you can use the following code to download and extract zip file from given uri path.
URL url = new URL(uriPath);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
InputStream in = connection.getInputStream();
ZipInputStream zipIn = new ZipInputStream(in);
ZipEntry entry = zipIn.getNextEntry();
while(entry != null) {
System.out.println(entry.getName());
if (!entry.isDirectory()) {
// if the entry is a file, extracts it
System.out.println("===File===");
} else {
System.out.println("===Directory===");
}
zipIn.closeEntry();
entry = zipIn.getNextEntry();
}
