Witam serdecznie
Mam pewien problem, z którym już od kilku godz. nie mogę sobie poradzić. Dla większości pewnie wyda się on banalny, jednak ja dopiero zaczynam zabawę z Javą, więc postanowiłem zwrócić się z prośbą o pomoc do Was.
Otóż mam programik w którym ustalam sobie wartość kolory w HEXach. Program pokazuje mi tą wartość w RGB. I teraz chciałbym, aby ta wartość RGB została wstawiona jako wartość tła. Innymi słowy... wybieram sobie kolor w HEXach, pokazuje mi go w RGB i zmienia mi tło na wybrany kolor. Może to być zmiana automatyczna, a może być po wciśnięciu przycisku. To już jest mi obojętne ;)
Oto kod programu:
package javaapplication2;
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class colors3 extends Applet implements ItemListener {
String tabwsp[][]=

No i tutaj mamy wartość w RGB - "tabwsp[n1][n2] + ", " + tabwsp[n3][n4] + ", " + tabwsp[n5][n6]", która pojawia nam się w polu tekstowym. Chciałbym żeby właśnie ona wyznaczała mi tło :)
