Вот код:
public static String savePage(final String URL) throws IOException {
String line = "", all = "";
URL myUrl = null;
BufferedReader in = null;
try {
myUrl = new URL(URL);
in = new BufferedReader(new InputStreamReader(myUrl.openStream()));
while ((line = in.readLine()) != null) {
all += line;
}
} finally {
if (in != null) {
in.close();
}
}
return all;
}
Теперь вы можете обрабатывать одну строку за другой в цикле while.
