Kald af metode som ligger under en klasse

Kender ikke rigtigt noget til applets.. men gøre metoden statisk eller oprettet en instans af objektet?

Det burde være det samme uanset om det er en applet eller en applikation.

Det er desværre ikee helt det samme.. Jeg ved i hverfald ikke hvad jeg skal gøre med det der står i mainen.

Jeg refererede specifikt til metoden i den anden klasse.

Indholdet af main må enten skulel slettes eller flyttes til init metoden.

Tak, jeg kigger på det.. Har du fået poient? er ikke helt sikker på jeg har gjort det rigtigt.. Hvis ikke hvordan gør man så?

jeg ligget et svar (kommer her)

du accepterer

Jeg har muligvis nogle eksempler på kode som både er i applet og applikation.

Interesseret ?

Ja, det kunne være rigtig fint med kode i både applet og applicaton
