How to place popup menu on clicking a Component

Question

Hi everybody.
I have a swing application where I have JFrame and so many components in that. I want to open Popup menu on clicking a button. The menu should have three menu items into that. It looks very simple but I am not sure how should I do that.
If possible, try to explain it with small piece of code.
Thanks in advance.

yourJbutton.addMouseListener(new MouseAdapter() { //Listen for mouse events
  public void mousePressed(MouseEvent e) {
    if (SwingUtilities.isRightMouseButton(e) == true && e.isMetaDown() == true) {
      JPopupMenu popup = new JPopupMenu();
      JMenuItem mItem = new JMenuItem("Something");
      mItem.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
          // do your thing
      popup.add(mItem);
      popup.addSeparator();
      mItem = new JMenuItem("Close Popup");
      mItem.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {}});
      popup.add(mItem);
      popup.show(e.getComponent(), e.getX(), e.getY());
});
