bufferedreader

I am using the following bufferedreader to read the lines of a file, BufferedReader reader = new BufferedReader(new FileReader(somepath)); while ((line1 = reader.readLine()) != null) { //some code } Now, I want to skip reading the first line of the file and I don't want to use a counter line int lineno to keep a count of the lines. How to do this? You can try this BufferedReader reader = new BufferedReader(new FileReader(somepath)); reader.readLine(); // this will read the first line String line1=null; while ((line1 = reader.readLine()) != null){ //loop will run from 2nd line //some code } Use

I'm having a problem with a Java SocketServer, i'm building a very basic Java handled Web Server. So i'm creating a socket server, this is the code from the run method as i have made the server threaded. The problem i'm having is that the server code seems to freeze as while((line = reader.readLine()) != null) until the remote client closes the connection. I'm using the chrome plugin ARC (Advanced REST Client) to do the testing with. public void start() throws ServerException{ this.running = true; try{ this.server = new ServerSocket(this.port); }catch(IOException ex){ System.err.println(

I want to prompt the user to begin entering characters and I want them to be able to enter characters as long as they want until they hit control+d to exit. For example, they can type a string of numbers like: 1234567 and as soon as they decide to hit control+d the line that they entered will be displayed (so without having to hit return) I am thinking I'll need a buffered reader or something. Any suggestions? What rlibby said is spot on: the CTL-D will cause the terminal to flush buffered input to the JVM. However, the keypress event itself is captured and acted on by the terminal and not

Here is my code: try { String textLine; FileReader fr = new FileReader("ad.txt"); BufferedReader reader = new BufferedReader(fr); while((textLine=reader.readLine()) != null) { textLine = reader.readLine(); jTextArea1.read(reader, "jTextArea1"); } } catch (IOException ioe) { System.err.println(ioe); System.exit(1); } And my .txt file contains the following: contig00001 length=586 numreads=4 CGGGAAATTATCcGCGCCTTCACCGCCGCCGGTTCCACCGACGAACGGATACTGCGtGaa ggCCGCGATCCCGTCggaCGGAAAaCGCCcTGGCCCGGGAaCATACCGTTCGGGCCGCCA AGTGTTATAGCCGGACCACTTGTCAGAACATTTCCaaTCCGAAGATGTGAGTtCGGAAGg

I want to send a command to a server, and find out if I get a response. Right now i am using BufferedReader 's readline() function, which blocks until there's a response from server, but all I want to do is verify that there's a response from the server in the first place. I tried using ready() or reset() to avoid this block, but it doesn't help. This is causing my program to get stuck waiting for the server to respond, which never happens. InputStreamReader seems to do the same thing, by my understanding of things. Other questions I found here on the subject didn't answer my question, so

How do you convert a String to int when using BufferedReader? as far as i remember,its something like below: System.out.println("input a number"); int n=Integer.parseInt(br.readLine(System.in)); but for some reason,its not working. the error message says: no suitable method found for readLine(java.io.InputStream) it also says br.readLine is not applicable An InputStreamReader needs to be specified in the constructor for the BufferedReader . The InputStreamReader turns the byte streams to character streams. As others have mentioned be cognizant of the exceptions that can be thrown from this

This question already has an answer here: Proper way to close an AutoCloseable 1 answer I wrote a simple server and client example as below . Client : Open a connection Get outputstream , write to stream and close the output stream Get inputstream and read from the stream. Getting exception at this point public class DateServer { public static void main(String[] args) throws InterruptedException { ServerSocket serverSocket = null; Socket client = null; try { serverSocket = new ServerSocket(6013); while (true) { client = serverSocket.accept(); OutputStream outputStream = client.getOutputStream(
