name;

Path path = Paths.get(dest).getParent().toAbsolutePath().normalize();

if(!Files.exists(path))
{
try {
Files.createDirectories(path);
} catch (IOException e) {
e.printStackTrace();
}
}

try (FileChannel fc = new FileOutputStream(dest).getChannel()){

ByteBuffer buffer = getResponseAttachment(url);
fc.write(buffer);
} catch (IOException e) {
e.printStackTrace();
}

 

import java.io.File;
import java.io.FileOutputStream;
import java.nio.ByteBuffer;
import java.nio.channels.FileChannel;

public class Main {
public static void main(String[] argv) throws Exception {
ByteBuffer bbuf = ByteBuffer.allocate(100);
File file = new File("filename");

boolean append = false;

FileChannel wChannel = new FileOutputStream(file, append).getChannel();

wChannel.write(bbuf);

wChannel.close();
}
}

String dest = "d:/download/" + name;
try (FileChannel fc = FileChannel.open(Paths.get(dest), StandardOpenOption.WRITE)){
ByteBuffer buffer = getResponseAttachment(url);
fc.write(buffer);
} catch (IOException e) {
e.printStackTrace();
}
