I am trying to make this function download file from the internet. I pass two arguments to it: from - url to file on the net, to - local file path; The problem it throws IOException when opening stream: Authority expected at index 7: http:// Here is my code: private boolean downloadFile(String pathFrom, String pathTo) { URL url; ReadableByteChannel rbc; FileOutputStream fos; try { url = new URL(pathFrom); rbc = Channels.newChannel(url.openStream()); fos = new FileOutputStream(pathTo); fos.getChannel().transferFrom(rbc, 0, 1 << 24); return true; } catch (MalformedURLException e) { Log.e(TAG,

All, I am trying to ensure that a file I have open with BufferedReader is closed when I catch an IOException, but it appears as if my BufferedReader object is out of scope in the catch block. public static ArrayList readFiletoArrayList(String fileName, ArrayList fileArrayList) { fileArrayList.removeAll(fileArrayList); try { //open the file for reading BufferedReader fileIn = new BufferedReader(new FileReader(fileName)); // add line by line to array list, until end of file is reached // when buffered reader returns null (todo). while(true){ fileArrayList.add(fileIn.readLine()); } }catch

Is the FileNotFoundException somehow a "sub-exception" of the IOException? This is my code opening an input stream to a file at the given path: method(){ FileInputStream fs; try { fs = new FileInputStream(path); // fs.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } How come I can neglect the FileNotFound and just catch the IOException instead? Is the FNFException a part of the IOException? Instead of catching the exceptions, what if I throw an IOException in my method? method() throws IOException{ FileInputStream fs; fs = new
