Código:
public class Uf {
public static void Ufdeldia(String[] args) {
int i=1;
int n=1;
String uf=null;
String palabra;
try {
// Indicamos la URL donde nos conectamos
URL url = new URL("http://valoruf.cl/");
// Buffer con los datos recibidos
BufferedReader in = null;
try {
// Volcamos lo recibido al buffer
in = new BufferedReader(new InputStreamReader(url.openStream()));
} catch(Throwable t){}
// Transformamos el contenido del buffer a texto
String inputLine;
String inputText="";
// Mientras haya cosas en el buffer las volcamos a las
// cadenas de texto
while ((inputLine = in.readLine()) != null)
{
StringTokenizer stk =new StringTokenizer (inputLine);
inputText = inputText +"\n"+ inputLine;
while (stk.hasMoreTokens())
{
palabra = stk.nextToken();
// System.out.print(i+".");
// System.out.print(n);
if(i==58 & n==6) {
uf=palabra;
System.out.println(palabra);
}
n=n+1;
}
i=i+1;
n=1;
}
// Mostramos el contenido y cerramos la entrada
// System.out.println("El contenido de la URL es: " + inputText);
// in.close();
} catch (MalformedURLException me) {
System.out.println("URL erronea");
} catch (IOException ioe) {
System.out.println("Error IO");
}
char arregloChar[] = new char[9];
uf.getChars( 0, 9, arregloChar, 0 );
// for ( int cuenta = 0; cuenta < arregloChar.length; cuenta++ )
// salida += arregloChar[ cuenta ];
System.out.print(arregloChar);
}
}
y esta es la frame que al precionar un botos quiero que me muestre el arreglo "arregloChar" en un texfile
