JMenuItems are selected by default

Question

When I run my application and click on the Menu items, My JMenuItems are shown as selected. Once I hover the mouse on each menu item, they get de-selected after that they work normally. That is, only the menu item that gets the mouse on it gets selected. What is the problem, I checked up my code I see nothing wrong with it. tnx for any idea u may have

Answer 1

I think you want me to elaborate the question here it is.
I have a JMenu named 'File'. I have many JMenuItems under the 'File' JMenu. When I click on the 'File' JMenu, I see all the JMenuItems. And all of them are selected! Here is how I implemented the JMenuItems
public class NewFile extends JMenuItem{      //the other menu items are implemented in a similar way
     public NewFile(String str){
          super(str);
          setArmed(true);
          addActionListener(
               new ActionListener(){
                    public void actionPerformed(ActionEvent e){
}I then added an instance of the FileMenuItem to FileMenu in this way
class FileMenu extends JMenu{
     private NewFile newFile;     
     public FileMenu(String str){
          super(str);          
          newFile = new NewFile("New");
          openFile = new OpenFile("Open");
          closeFile = new CloseFile("Close");
          saveFile = new SaveFile("Save");
          printFile = new PrintFile("Print");
          exitFile = new ExitFile("Exit");
          add(newFile);
          add(openFile);
          add(closeFile);
          addSeparator();
          add(saveFile);
          addSeparator();
          add(printFile);
          addSeparator();
          add(exitFile);
}I'm trying to make it work as follows. A JMenuItem should be selected only when I click on it!
Tnx
