java - JFileChooser won't work properly -

i working jfilechooser , want make show file selection dialog display when fileitem1 clicked. here swingmenu class.

question: missing/doing wrong in showfilechooser method? in advance.

import javax.swing.*; import javax.swing.filechooser.filenameextensionfilter; import java.awt.event.actionevent; import java.io.file; import java.awt.event.actionlistener;  /* *this class encapsulates build of menu bar , called drawpanelmain add jframe  */ public class swingmenu extends jmenubar {      /*     * initializes jmenuitems added menu.  necessary     * access actionevent handler.  includes filechooser used     * actionevent of clicking on fileitem1.      */     private jmenuitem fileitem1 = null;     private jmenuitem fileitem2 = null;     private jmenuitem edititem1 = null;     private jmenuitem helpitem1 = null;     private jmenuitem toolsitem1 = null;      /*     * create jfilechooser used in actionevent click on fileitem1      */     jfilechooser chooser = new jfilechooser("desktop");      /*     *these main items on menubar     */     public swingmenu(){initmenubar();}              private void initmenubar() {                 /*                 *initializes main items on menubar                  */                 jmenu filemenu = new jmenu("file");                 jmenu editmenu = new jmenu("edit");                 jmenu toolsmenu = new jmenu("tools");                 jmenu helpmenu = new jmenu("help");                  /*                 *initializes components of main items                  */                 jmenuitem fileitem1 = new jmenuitem("open");                 jmenuitem fileitem2 = new jmenuitem("save");                 jmenuitem edititem1 = new jmenuitem("edit configuration");                 jmenuitem helpitem1 = new jmenuitem("user manual");                 jmenuitem toolsitem1 = new jmenuitem("fetch configuration");                  /*                  * add action listener fileitem1 use in jfilechooser actionevent                  */                 fileitem1.addactionlistener(new actionlistener() {                     public void showfilechooser (actionevent e){                         chooser.setfileselectionmode(jfilechooser.files_and_directories);                         filenameextensionfilter filter = new filenameextensionfilter("directories , xml files", "xml");                         chooser.setfilefilter(filter);                         int returnval = chooser.showopendialog(this);                         if (returnval == jfilechooser.approve_option) {                             string path = chooser.getselectedfile().getabsolutepath();                             joptionpane.showmessagedialog(null, "you selected" + path);                         }                     }                 });                  /*                 *each component added assigned menu item                  */                 filemenu.add(fileitem1);                 filemenu.add(fileitem2);                 editmenu.add(edititem1);                 toolsmenu.add(toolsitem1);                 helpmenu.add(helpitem1);                  /*                 *menu items added menubar                  */                 add(filemenu);                 add(editmenu);                 add(toolsmenu);                 add(helpmenu);             } } 

the problem this: public void showfilechooser (actionevent e){. in java, event handling method needs public void actionperformed(actionevent e) {:

                fileitem1.addactionlistener(new actionlistener() {                     @override                     public void actionperformed(actionevent e) {                         chooser.setfileselectionmode(jfilechooser.files_and_directories);                         filenameextensionfilter filter = new filenameextensionfilter("directories , xml files", "xml");                         chooser.setfilefilter(filter);                         int returnval = chooser.showopendialog(this);                         if (returnval == jfilechooser.approve_option) {                             string path = chooser.getselectedfile().getabsolutepath();                             joptionpane.showmessagedialog(null, "you selected" + path);                         }                     }                 });
