java - Method does not work properly before executing System.exit(0) -
i new in java, have swing application menu file/exit, application editor, when select option exit menu application ask me if want save changes before exit, see exit code below
class actionexit extends abstractaction { public actionexit() { super("exit",icons.iconexit); setenabled(true); putvalue("menu", "file"); putvalue("menuindex", "99"); } public void actionperformed(actionevent evt) { saveandclose(); <----does not execute instructions savesettings(); system.exit(0); } } the problem have in method saveandclose(), here check if document has changed , display dialog question/options (save? yes,no), execute other methods connect database , apply changes made document etc. method executes first instructions , seems being interrupted (i put lot of "system.out.println" find method stops), application returns , continues next method , ends. if debug application works perfectly, not work when runs normally. why happens?, can make/force application save changes before exit?
** here code of saveandclose **
basically doing here is, main frame try find component(panel) want close, once find execute instruction:
(panelmember)component[y]).closetab()
i reuse method, called in option in menu (window/close-panel) , when click in panel contains document , select 'x' close it
public void saveandclose() { component[] component =this.getcomponents(); (int y = 0; y < component.length; y++) { if ((component[y] instanceof container)) { saveandclose2((container)component[y]); } } } public void saveandclose2(container pcont) { component[] component = pcont.getcomponents(); (int y = 0; y < component.length; y++) { if ((component[y] instanceof container)) { if ((component[y] instanceof panelmember)) { ((panelmember)component[y]).closetab(); } closetabsinpanel2((container)component[y]); } } } here rest of programs/methods executed, thank help
