passer d'une fenetre à une autre dans une application cdc

slt à tous , alors voila, mon probleme c que je suis sensé créer une applicaion pour pda, et j'utilise pour cela netbeans, et en mettant le code suivant

frame1.setVisible(false);

MaJFrame frame2 = new MaJFrame();

frame2.setVisible(true);

pour qu'en cliquant sur un bouton la frame dans laquelle se trouve le bouton ne soit plus visible et une autre apparaisse, ça ne marche pas, c urgent , merci d'avance.

il faudrait peut etre mettre une taille et une position a ta nouvelle fenetre.

sans plus d'informations (ni bout de code digne de ce nom) on ne va pas pouvoir deviner.

et surtout :nosms: , urgence ou pas, ce n'est pas une excuse.

désolé si j'ai écris en langage sms, mais je ne m'en suis pas rendu compte, et je ne pense pas que j'ai exagerer dans l'utilisation de ce genre de langage ,alors pour ce qui est du code, en fait, avec netbeans j'ai créer une application cdc, ce qui génére automatiquement une form main qui contient une jframe, et j'ai mis un bouton swing , voila le code
