Hi i create two file one contains the JMenuBar and the components and the second contains the JFrame

/* This is the main Frame class withch reprasend the core of all program. Hire is tacke a place this components : MenuBar from where the user can choose the whays to continue the simulation. Left panel is used furder in the aplication. */ package classes; import javax.swing.*; import java.awt.*; public class firmFrame { //The constructor of the class firmFrame() { //We create the Menu bar with the Menu components JMenuBar firmBar = new JMenuBar(); JMenu createNEW = new JMenu("Ñúçäàè ôèðìà"); createNEW.addSeparator(); JMenu economic = new JMenu("Èêîíîìèêà"); economic.addSeparator(); JMenu progres = new JMenu("Ïàçàð"); progres.addSeparator(); JMenu institucion = new JMenu("Èíñòèòóöèè"); institucion.addSeparator(); // We create the JMenuItem conected wuth the diferent categoris JMenuItem newFirm = new JMenuItem("íîâà ôèðìà"); /* This Items are conected with the category "Economic" in this Iems * the user can choose haw to manage his bisiness. */ JMenuItem marketing = new JMenuItem("Ìàðêåòèíã"); JMenuItem schetovodstvo = new JMenuItem("Ñ÷åòîâîäñòâî"); JMenuItem menidgmant = new JMenuItem("Ìåíèäæìúíò"); JMenuItem proizvodstvo = new JMenuItem("Ïðîèçâîäñòâî"); /* This Items are conected with the category "Progras" in this Iems * the user can choose where to construct his units. */ JMenuItem magazini = new JMenuItem("Ìàãàçèíè"); JMenuItem fabriki = new JMenuItem("Ôàáðèêè"); /* This Items are conected with the category "Institucion" in this Iems * the user can choose diferent institucions whith witch can work. */ JMenuItem buro = new JMenuItem("Áþðî ïî òðóäà"); JMenuItem kantori = new JMenuItem("Êàíòîðè"); JMenuItem banka = new JMenuItem("Áàíêà"); // ADD the Menus to firmBar() firmBar.add(createNEW); firmBar.add(economic); firmBar.add(progres); firmBar.add(institucion); // ADD the MenuItems to Menus createNEW.add(newFirm); economic.add(marketing); economic.add(schetovodstvo); economic.add(menidgmant); economic.add(proizvodstvo); progres.add(magazini); progres.add(fabriki); institucion.add(buro); institucion.add(kantori); institucion.add(buro); } }



and the second


package classes; import javax.swing.*; public class mainFraim { mainFraim() { firmFrame ff = new firmFrame(); JFrame frame = new JFrame(); frame.add(ff); /* or frame.setJMenuBar(ff); when i put tis the resolt is the same */ } public static void main (String args[]) { new mainFraim(); } }
