Archief - JAVA hulp bij fout

ik krijg de volgende foutmelding als ik een nieuw form wil openen via een knop maar snap er niets meer van.
Dus graag iemand die me even terug in de goede richting duwt.

code :

public void vormingform()

{
Vormingen b= new Vormingen();
b.setExtendedState(JFrame.MAXIMIZED_BOTH);
b.setVisible(true);
b.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

}

Error:

iets meer code zou wel mogen.

nuja, die "Caused by: java.lang.UnsupportedOperationException: Not yet implemented" doet me vermoeden dat je een methode aanroept die je vergeten te implementeren bent.

Inderdaad. Kijk eens op lijn 170 van MAINMENU.java en het zal wel duidelijk worden.

ok, opgelost dank je
