bufferedreader

I'm trying to read a text file line by line using InputStream from the assets directory in Android. I want to convert the InputStream to a BufferedReader to be able to use the readLine(). I have the following code: InputStream is; is = myContext.getAssets().open ("file.txt"); BufferedReader br = new BufferedReader (is); The third line drops the following error: Multiple markers at this line The constructor BufferedReader (InputStream) is undefinded. What I'm trying to do in C would be something like: StreamReader file; file = File.OpenText ("file.txt"); line = file.ReadLine(); line = file

I just learned about input/output using BufferedReader . I wanted to know what exactly are the meanings of the term Stream and Buffer ? Also what does this line of code serves us: BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); Java has two kinds of classes for input and output (I/O): streams and readers/writers . Streams ( InputStream , OutputStream and everything that extends these) are for reading and writing binary data from files, the network, or whatever other device. Readers and writers are for reading and writing text (characters). They are a layer on top of

I am getting the following error in my Java program: Java variables not initialized error... error : variable nam and r not initialized location class child But nan and r already initialized, yet I am still getting the same error. public class cla { int rn; String name; void get(String a, int x) { name = a; rn = x; } void display() { System.out.println("student name: " + name + "roll no.:" + rn); } } import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class child { public static void main(String args[]) throws IOException { String nam; int r;

How does one set a timeout on a BufferedReader and a PrintWriter created using a socket connection? Here is the code I have for the server right now, which works until either the server or the client crashes: while(isReceiving){ str = null; BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream())); PrintWriter pw = new PrintWriter(socket.getOutputStream(), true); while ((str = br.readLine()) != null){ System.out.println("Processing command " + str); pw.println(client.message(str)); } } Outside the scope of this code I have imposed a socket timeout of 1000ms, which

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-application writes something to the socket, the code in the loop (in the server-application) will be executed. But I do not understand how it works. inputLine = input.readLine() waits until something appears in the buffered reader and when something appears there it returns
