问题 Im going to start by posting what the data from the text file looks like, this is just 4 lines of it, the actually file is a couple hundred lines long.

问题 I have the following statement: DataInputStream is = new DataInputStream(process.getInputStream()); I would like to print the contents of this input stream but I dont know the size of this stream. How should I read this stream and print it? 回答1: It is common to all Streams, that the length is not known in advance. Using a standard InputStream the usual solution is to simply call read until -1 is returned. But I assume, that you have wrapped a standard InputStream with a DataInputStream for a

问题 I'm trying to read html code from a URL Connection. In one case the html file I'm trying to read includes 5 line breaks before the actual doc type declaration. In this case the input reader throws an exception for EOF. URL pageUrl = new URL( "http://www.nytimes.com/2011/03/15/sports/basketball/15nbaround.html" ); URLConnection getConn = pageUrl.openConnection(); getConn.connect(); DataInputStream dis = new DataInputStream(getConn.getInputStream()); //some read method here Has anyone ran into

问题 Goal: Get the data from a .dat file and print it to the console in Eclipse Resources : fpfret.java and PointF.java and dichromatic.dat I have resolved all my issues and have just a few console errors, here's my code and my question is: How do I add the getCodeBase() method? package frp3; import java.io.BufferedInputStream; import java.io.DataInputStream; import java.io.EOFException; import java.net.URL; import java.util.Vector; public class FileRead { public static void main(String[] args) {

问题 My client/server application currently keeps opening and closing new connections every time it wants to send/receive data. I'm trying to change it so it will have one persistent connection. The problem I'm having is the socket's DataInputStream on the server keeps throwing EOFException's when I just want it to block until it receives the next batch of data. I thought about just simply writing the server like this... while socket is open { while at socket's DataInputStream's EOF { wait a

问题 The question "How to read a local (res/raw) file line by line?" deals with a similar issue but I was unable to construct a solution base on the answers provided there. I did get a very useful piece of info (the DataInputStream class which has a readLine method), and I have been researching this on the developer website and trying to make it work. What I am trying to do is read information stored in successive lines of a text file into a string array, such that the first line is the first

问题 this is my Client code Random rand = new Random(); int n = rand.nextInt(50) + 1; DataInputStream dis = new DataInputStream(_socket.getInputStream()); DataOutputStream dos = new DataOutputStream(_socket.getOutputStream()); dos.writeInt(n); and this is the Server code try { DataInputStream dis = new DataInputStream(socket.getInputStream()); BufferedReader input = new BufferedReader(new InputStreamReader(dis)); int fromClient = input.read(); System.out.println(fromClient); } catch (IOException e

问题 How can I write/read a string from a binary file? I've tried using writeUTF / readUTF (DataOutputStream/DataInputStream) but it was too much of a hassle. Thanks. 回答1: Forget about FileWriter, DataOutputStream for a moment. For binary data one uses OutputStream and InputStream classes. They handle byte[] . For text data one uses Reader and Writer classes. They handle String which can store all kind of text, as it internally uses Unicode. The crossover from text to binary data can be done by

问题 I ve created a simple MultiThreaded server. Everytime it accepts client a DataInputStream and DataOutputStream is created and the comunication start Server: public class Connection implements Runnable{ boolean isAlreadyOpened = false; @Override public void run() { // TODO Auto-generated method stub try { ServerSocket ss = new ServerSocket(7000); while(true){ System.out.println("Il Server sta cercando Connessioni"); Socket s = ss.accept(); System.out.println("Il Server ha accettato un Client")

问题 Suppose we have some binary data byte[] data that only contains Integers. If I wanted to read this data utilizing a DataInputStream , the only approach I can come up with is the following: DataInputStream in = new DataInputStream(new ByteArrayInputStream(data)); try { while (true){ int i = in.readInt(); } } catch (EOFException e) { // we're done! } catch (IOException e){ throw new RuntimeException(e); } What bugs me about this is that reaching the end of the stream is expected and it would
