Question

I got one JMenuItem with start code. How can I get when I click one icon that the code will start?

private void jMenuItemActionPerformed(java.awt.event.ActionEvent evt) {   
  String color="blue";
}

private void IconActionPerformed(java.awt.event.ActionEvent evt) {
  // here i dont know how start JmenuItem when i click on it
  get.jMenuItemActionPerformed; 
}

Looks like you haven’t added an ActionListener to your JMenuItem. An ActionListener waits until some action is performed (e.g. clicking) on a GUI component, then calls some code. For example:

JMenuItem myMenuItem = new JMenuItem("Hello");
myMenuItem.addActionListener(new ActionListener()
{
    public void actionPerformed(ActionEvent e)
    {
        System.out.println("Hello button clicked!"); // or call some other method
    }
});
