Imam problem sa jednim zadatkom, uradio sam u C++ zadatak jedan, ali sada sma hteo to u javi da odradim, i izbacuje mi konstante greske.

Resio sam problem, ali sad imam odmah novi, zelim da u pocetku se prikaze jedan message dialog, i kada se klikne na ok, da se meni pokaze forma. Ali kada pritisnem Ok, pojavi se prazna forma. Kako da se povezem na to sto sam pravio preko tog message dialoga
public PrelamanjeForm() {
setTitle("Example");
