Dlaczego nie mogę przechwycić wyjątku?

Na pierwszy rzut oka nie widać skąd dokładnie leci ten wyjątek, bo podałeś za krótki zrzut stosu. Kod łapiący wyjątek wygląda ok, więc można zgadywać, że być może wyjątek leci z innego miejsca aplikacji niż otoczone try-catch.

Jeśli to możliwe podeślij pełny stack-trace błędu.Tomasz Dziurko edytował(a) ten post dnia 16.07.10 o godzinie 11:51

Też mi się wydaje, że to leci z innego miejsca. Zakomentuj wszystko w tej metodzie i zobacz czy działa.

Wyjątek pojawia się w metodzie Licz (at CalcFRAME.Licz(CalcFRAME.java:658). Metoda slowo jest ok. Nie łapiesz w Licz() wyjątku.

Jeśli chodzi o obsługę wyjątków to lepiej dawać bardziej precyzyjne wyjątki w catch. catch(Exception e) wyłapuje wszystkie wyjątki, dlatego nie powinno się tego używać. Powiedzmy, że w try może zostać wyrzuconych kilka wyjątków i każdy rodzaj wyjątków powinien być obsłużony oddzielnie (w oddzielnej klauzuli catch).

try{
//kod
}catch(Exception1 e){
//obsługa wyjątku Exception1
}catch(Exception2 e){
//obsługa wyjątku Exception2
}
Jeśli jakiś wyjątek jest podklasą innego wyjątku to musi być w wyższej klauzuli catch (Exception1 może być podklasą Exception2, ale nie na odwrót)

Powinieneś wyłapywać wyjątek NumberFormatException, a nie Exception

Skoro prosisz o uwagi do kodu i uczysz się javy (programowania) to kilka rad:

Java po to jest obiektowa żeby z tego korzystać, ty całą aplikację umieściłeś w jednej klasie - nie dziw się potem, że nie możesz wyszukać gdzie jest błąd. Oddziel sobie kod "logiki" od okienek. Jeśli używasz jakiegoś IDE (z kodu widzę ze Netbeans) korzystaj z jego pomocy. W konsoli, po wystąpieniu błędu, możesz sobie kliknąć dokładnie w miejsce jego wystąpienia.
W jednej klasie umieściłeś kilkadziesiąt pól (przyciski, etykiety itp), ja w tak skomplikowanych ekranach dziele sobie je na pod-ekrany (np JPanel'e) i rozdzielam logikę zarządzania nimi - oprócz tego nie nazywaj pól jlabel1, jlabel2 bo za tydzień nie będziesz wiedział o co chodzi.
Używasz generatora kodu, zdania co do jego użyteczności są podzielone, ale jeśli już się na niego zdecydowałeś, zostaw ten kod w spokoju i nigdy tam nie zaglądaj, nie mówiąc już o dopisywaniu obok własnego.
Następna rzecz to duplikacje: najprostsza rzecz to wyłączyć je do metod, w twoim kodzie taki potworek jest powtórzony 4 razy:

 B_IP2=IP2.getText();

        B_IP2b=Integer.parseInt(B_IP2);

        B_IP2bb=Integer.toBinaryString(B_IP2b);

        int i2=B_IP1bb.length();



          if (i2<8) {

       while (i2 <8){



         B_IP2bb="0"+B_IP2bb;

           ++i2;

      }


jeśli znajdziesz tam błąd będziesz musiał 4 razy go poprawiać!
co do zasad łapania wyjątków już pisał Rafał.
