Ejemplos de uso :

Code:

public class Main {

   public static void main(String[] args) {
       DH_Tools tools = new DH_Tools();
       //String codigo = tools.toma("http://localhost/");
       //String codigo = tools.tomar("http://localhost/login.php", "usuario=test&amp;password=dsdsads&amp;control=Login");
       //tools.savefile("c:/xampp/texto.txt","texto");
       //String codigo = tools.read_file("c:/xampp/texto.txt");
       //String codigo = tools.console("ver");
       //String codigo = tools.httpfinger("http://www.petardas.com");
       /*
        ArrayList array = new ArrayList();
        Collections.addAll(array, "http://localhost/sql.php?id=dsaadsds", "b", "http://localhost/sql.php?id=dsaadsds", "c");
        ArrayList array2 = tools.repes(tools.cortar(array));
        for (int i = 0; i &lt; array2.size(); i++) {
        System.out.println(array2.get(i));
        }
        */
       //System.out.println(tools.regex("1sadasdsa2","1","2"));
       //System.out.println(tools.response_code("http://www.petardas.com/"));
       /*
        File savefile = new File("c:/xampp/mierda.avi");
        if(tools.download("http://localhost/test.avi",savefile)) {
        System.out.println("yeah");
        }
        */

       //System.out.println(tools.extract_file_by_url("http://localhost/dsaads/dsadsads/index.php"));
       //System.out.println(tools.uri_split("http://localhost/index.php?id=dadsdsa","query"));
       //System.out.println(tools.md5_encode("123"));
       //System.out.println(tools.md5_file("c:\\xampp\\texto.txt"));
       //System.out.println(tools.get_ip("www.petardas.com"));
