The Java core API provides classes in the java.net package to handle basic networking functions. The URL class represents a pointer to a network resource, like the actual address. The URL-Connection class represents a network connection to that resource. The following code takes a URL as an argument and prints its contents one line at a time:
import java.io.*;import java.net.*;public final class FetchURL { public static final void main(String[] args) { String address; URL url; URLConnection connection; BufferedReader input; address = args[0]; try { url = new URL(address); connection = url.openConnection(); input = new BufferedReader( new InputStreamReader( connection.getInputStream())); while((address = input.readLine()) != null) System.out.println(address); } catch(IOException e) { e.printStackTrace(); } }}
