提问by ADESH RAJPUT
I am working on swings. I have to create a mainscreen consisting 10 menus. I have created the form by JFrame and menu by JMenu. Now that menu should contain text and image both and action performed method should be called on clicking of the menu so that action could be performed on clicking of the menu button.

Use the constructor JMenuItem(String text, Icon icon)
If you want JMenu with Icon and Text do
使用构造函数JMenuItem(String text, Icon icon)
如果你想要带有图标和文本的 JMenu 做
helpmenu= new JMenu(" Help ");
helpmenu.setIcon(..);

-For the JMenuItemuse JMenuItem((String text, Icon icon)constructor,
-对于JMenuItem使用JMenuItem((String text, Icon icon)构造函数，
-And for JMenutry using the constructorwhich takes String as an Argument JMenu(String s), and methodsetIcon()
-并JMenu尝试使用将 String 作为 Argument和方法的构造函数JMenu(String s)setIcon()
For setting the special key options on the MenuItems usesetAccelerator()
要在 MenuItems 上设置特殊键选项，请使用setAccelerator()
Eg:
例如：
myItem.setAccelerator(
KeyStroke.getKeyStroke(KeyEvent.VK_P, ActionEvent.CTRL_MASK));
myItem.setAccelerator(
KeyStroke.getKeyStroke(KeyEvent.VK_P, ActionEvent.CTRL_MASK));

Set the icon and text in your Actionwhich you place on the menu (using the key-value pair mechanism). The keys are defined in the Actioninterface.
设置Action您放置在菜单上的图标和文本（使用键值对机制）。键在Action接口中定义。
The class javadoc of the Actioninterfacealso contains a nice overview table of the available keys and what they affect.
该接口的类 javadocAction还包含一个很好的可用键及其影响的概述表。
