bufferedreader

I am using BufferedReader.readLine() method to read a response from a remote server (which is written in C and I have no access to source code). BufferedReader br = new BufferedReader(new InputStreamReader(in)); String line; while((line = br.readLine())!=null){ [...] } But it always blocks at the last line until it times out. So I used the following code: int b; while(true){ b = in.read; [...] } and I found out that the last byte read has an integer value of 13, which I think it is a carriage return, right? So why the readLine method blocks? How does the server usually signal an end of stream

Is there a way to check if in BufferedReader object is something to read? Something like C++ cin.peek() . Thanks. You can try the "boolean ready()" method. From the Java 6 API doc: "A buffered character stream is ready if the buffer is not empty, or if the underlying character stream is ready." BufferedReader r = new BufferedReader(reader); if(r.ready()) { r.read(); } Gavin H You can use a PushbackReader . Using that you can read a character, then unread it. This essentially allows you to push it back. PushbackReader pr = new PushbackReader(reader); char c = (char)pr.read(); // do something to

I need some help: I'm making a Supermarket simulation on Java, but I've got one problem, I have a text file (Stock.txt) where I have all the supermarket stock on it for example: 0-Bakery-Chocolate Cake-$12.5-250 1-Meat-Premium Steak-$2.6-120 2-Seafood-Tuna - $1.2-14 ... Where the first number is the "id" for the product, next is the department the product belongs, third is the name of the product, the next thing is the price, and the last number is how much pieces of the product the stock has. I have this class: public class Product { protected String name; protected double price; protected

I'm trying to read in a text file of a bunch of words that I want to use for a word game I am writing. This list is stored in the assets directory and is a txt file. But, whenever I attempt to open it, it throws an exception. List<String>wordList = new ArrayList<String>(); BufferedReader br = null; try { br = new BufferedReader(new InputStreamReader(getAssets().open("wordlist.txt"))); //throwing a FileNotFoundException? String word; while((word=br.readLine()) != null) wordList.add(word); //break txt file into different words, add to wordList } catch(IOException e) { e.printStackTrace(); }

What are the differences between BufferedReader , BufferedInputStream and Scanner in java? BufferedReader reads the text and BufferedInputStream reads byte . Is there any difference other than this? Igor I guess, the difference is the same as between reader and inputstream: one is character-based, another is byte-based. For example, reader normally supports encoding... Edit: Check this question: The difference between InputStream and InputStreamReader when reading multi-byte characters Kumaresh Babu BufferedInputStream reads the data in the buffer as bytes by using InputStream .
