Živjo, napisal sem program v javi v katerem označuješ JRadioButtne, ko pa klikneš gumb izračunaj , ti program v novem oknu izpiše "Vsota je..." + total.
Vse lepo in prav, ampak ko uporabnik zapre to okno in npr. spremeni en gumb(ali pa tudi ne) in kilkne izračunaj program vrne vsoto prejšnjih gumbov + vsoto sedaj izbranih gumbov.
Kako bi naredil gumb reset, ali pa še bolje neko textovno polje v katerem se vsota prikazuje sproti. Npr. ko označiš en gumb se doda 10, če potem označiš drugega (vrednost 25) in da izpiše vrednost 25 ne pa 35... Prosim za pomoč...

V splošnem pa bi morali biti nekako tako.
Za gumb Reset samo dodaš, da se s klikom na ta gumb vrednost spremenljivke, v katero se shranjuje vsota, nastavi na 0.
Za sprotno izpisovanje pa je potrebno uporabiti event oz. dogodek na JRadioButton in ko se ta dogodek zgodi, posodobiš vsoto ter jo izpišeš.
Fino bi bilo, če bi lahko prilepil kodo, kako imaš sedaj to narejeno, saj se le tako lahko poda bolj točen odogovor.

Najenostavneje je rešiti tako, da se v funkcijo actionPerformed
doda za
if (source == button) { naslednja vrstica:
total = 0;
Seveda pa ne na koncu pozabiti nastaviti gumba na visible, da zakomentiraš button.setVisible(false);
