Centering a JMenuItem in a JPopupMenu

What I want to do is to center the JMenuItem elements inside the JPopupMenu. This is how they currently appear image

I would like them to be in the center instead of the left side.

Here are some parts of my code

    JButton lvlBtn = new JButton("Level"); //For the button
    JPopupMenu pmenu = new JPopupMenu();
    JMenuItem easyMenuItem = new JMenuItem("Easy");
    JMenuItem mediumMenuItem = new JMenuItem("Medium");
    JMenuItem hardMenuItem = new JMenuItem("Hard");

    lvlBtn.setBounds(750, 20, 280, 50); //Setting a location for the button

    //Making an ActionListener for the button
    ActionListener btnAction=new ActionListener(){
            public void actionPerformed(ActionEvent ae)
            {
                //This will make the popup menu appear


                Component b=(Component)ae.getSource();

               // Taking the location of the button on the screen
               Point p=b.getLocationOnScreen();

               // this - current frame
               // 0,0 where the popup will initially appear
               pmenu.show(this,0,0);

               // Changing the location of the JPopupMenu and placing it
               // below the lvlBtn
               pmenu.setLocation(p.x,p.y+b.getHeight());
            }
        };
    lvlBtn.addActionListener(btnAction);

    //Setting a size for each JMenuItem
    easyMenuItem.setPreferredSize(new Dimension(280, 20));
    mediumMenuItem.setPreferredSize(new Dimension(280, 20));
    hardMenuItem.setPreferredSize(new Dimension(280, 20));


    //Adding menu items in popup menu
    pmenu.add(easyMenuItem);
    pmenu.add(mediumMenuItem);
    pmenu.add(hardMenuItem);

Read the JMenuItem API.

JMenuItem extends from AbstractButton.

AbstractButton is the base class for Swing components like JButton, JCheckBox, JMenuItem. As such it provides methods to customize the display of the text, icon etc.

Start with:

setHorizontalAlignment(...)

But check out the other methods available for future reference as well.
