Witam,
jestem początkującym programistą:)
używam netbeans już mam wszystko poukładane w projekcie niestety na wstępie mam problem z buttonem ponieważ nie mam pojęcia jak podpiąć go by uruchamiał on domyślną przeglądarkę i określoną stronę np. 4programmers.net/Forum jeśli byłby ktoś na tyle uprzejmy i pomógł byłbym niezmiernie wdzięczny
pozdrawiam

Umieść w obsłudze zdarzenia
Desktop.getDesktop().browse(new URI(strona_która_chcesz_odwiedzić"));
Wymagana jest obsługa błędów.

zapomniałem dodać, że jestem bardzo początkujący:)
czego brakuje:)
jButton2.setText("www.wp.pl");
jButton2.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
Desktop.getDesktop().browse(new URI("www.wp.pl"));
}
bo wiem,że pisałeś o tym przynajmniej 2 razy wcześniej ale ja po prostu dalej tego nie rozumiem więc jeśli można to proszę o łopatologiczne wyjaśnienie.
Z góry dziękuję.

To zadawaj pytania w dziale Newbie.
jButton2.setText("www.wp.pl");
jButton2.addActionListener(new java.awt.event.ActionListener()
{
public void actionPerformed(java.awt.event.ActionEvent evt)
{
try
{
Desktop.getDesktop().browse(new URI("www.wp.pl"));
}
catch(Exception ex)
{
System.out.println(ex);
}
}
});

Po jakiego grzyba stworzyłeś klasę URI?
0
No więc masz odpowiedź: idź po rozum do głowy i skasuj tą klasę URI a następnie dodaj odpowiednie importy...

Wielkie dzięki chłopaki już działa class URI stworzyłem przez przypadek jak mi jakiś błąd wywalało i zapomniałem ją skasować
