With this example we are going to demonstrate how to read text from a Socket. A Socket is an endpoint for communication between two machines. In short, to read text from a socket you should:
- Get the socket input stream, using
getInputStream()API method of Socket. - Create a new BufferedReader, using a new InputStreamReader with the socket input stream.
- Use
readLine()API method of BufferedReader to read the text. - Add the code to process the text read from the socket.
- Close the BufferedReader with
close()API method.
Let’s take a look at the code snippet that follows:
try {
BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String str;
while ((str = rd.readLine()) != null) {
process(str);
}
rd.close();
}
catch (IOException ioe) {
System.out.println("I/O Error " + ioe.getMessage());
}
This was an example of how to read text from a socket in Java.
