What is the difference between using a BufferedReader around the StringReader in the following code vs using the StringReader only? By loading up the DOM in line 2 of both examples, it seems like the BufferedReader is not necessary? InputSource is = new InputSource(new StringReader(html)); Document dom = XMLResource.load(is).ge...
I have two threads in Java. First thread is closing a bufferedreader (br.close()) When the second thread does a read on the same reader I get an IOException (Stream Closed) I get this exception even if I use br.ready() Is there a way to know if the stream is already closed? ...
I'm using BufferedReader and PrintWriter to go through each line of an input file, make a change to some lines, and output the result. If a line doesn't undergo a change, it's just printed as is to the output file. For some reason however, the process ends prematurely. The code looks something like this: BufferedReader in = new Buffered...
I'm reading a local file using a BufferedReader wrapped around a FileReader: BufferedReader reader = new BufferedReader(new FileReader(fileName)); // read the file // (error handling snipped) reader.close(); Do I need to close() the FileReader as well, or will the wrapper handle that? I've seen code where people do something like this...

Hello, Looking for a bit of help, I have currently written a HTTP server. It currently handles GET requests fine. However, whilst using POST the buffered reader seems to hang. When the request is stopped the rest of the input stream is read via the buffered reader. I have found a few things on google. I have tried changing the CRLF and ...
How buffered streams are working on the background and how it actually differs and what is the real advantage of using the same? Another Query,.. Since DataInputSytream is also Byte based, but it is having methods to readLine().. Whats the point in here ...
Please look through the below code, // A.java File file=new File("blah.txt"); FileWriter fwriter=new FileWriter(file); PrintWriter pwriter=new PrintWriter(fwriter); //B.java File file=new File("blah.txt"); FileWriter fwriter=new FileWriter(file); BufferedWriter bwriter=new BufferedWriter(bwriter); What is the difference between these...

Hi, I'm making a program in Java with Sockets. I can send commands to the client and from the client to the server. To read the commands I use a BufferedReader. To write them, a PrintWriter But now I want to transfer a file through that socket (Not simply create a second connection).First I write to the outputstream how many bytes the ...
Hello, me and my buddy are working on a program for our Object Oriented Programming course at college. We are trying to write text into a file as a database for information. The problem is that when we try to read the corresponding lines with BufferedReader we can't seem to figure out how to read the correct lines. The only functions ava...
I'm working on a project in which I have to read in a Grammar file (breaking it up into my data structure), with the goal of being able to generate a random "DearJohnLetter". My problem is that when reading in the .txt file, I don't know how find out whether the file was supposed to be a completely blank line or not, which is detriment...
Hey, I am making an HTTP get request to a website for an android application I am making. I am using a DefaultHttpClient and using HttpGet to issue the request. I get the entity response and from this obtain an InputStream object for getting the html of the page. I then cycle through the reply doing as follows: BufferedReader r = new...
I have the following example of reading from a buffered reader: while ((inputLine = input.readLine()) != null) { System.out.println("I got a message from a client: " + inputLine); } The code in the loop println will be executed whenever something appears in the buffered reader (input in this case). In my case, if a client-applicati...
Scanner s = null; try { s = new Scanner(new BufferedReader(new FileReader("rates.txt"))); for (int i=0; i<9; i++){ while(s.hasNext()){rates[i] = s.next();} System.out.println(rates[i]); } }catch (IOException e){ System.out.println(e); } finally { ...
I am trying to sort the dates from the earliest to the latest. I was thinking about using the bufferedreader and do a try searching the first 2 characters of the string and then the 4th and 5th characters and finally the 7th and 8th characters, ignoring the slashes. The following is an example of the text file I have: 04/24/2010 - 200...
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 { ...
I want to make an HTTP request and then get the response as sketched here: URLConnection c = new URL("http://foo.com").openConnection(); c.setDoOutput(true); /* write an http request here using a new OutputStreamWriter(c.getOutputStream) */ BufferedReader reader = new BufferedReader(new InputStreamReader(c.getInputStream)); reader.rea...
Is there a easy way to skip the readLine() method in java if it takes longer than, say, 2 seconds? Here's the context in which I'm asking this question: public void run() { boolean looping = true; while(looping) { for(int x = 0; x<clientList.size(); x++) { try { Comm s = clientList.get(x); ...
