JMenuItem和JMenu有什么区别？
JMenu m;
JMenuItem i;
最佳答案
一个JMenu是菜单本身，或者如文档所述:
An implementation of a menu -- a popup window containing
JMenuItems that is displayed when the user selects an item on theJMenuBar.
一个JMenuItem是此类菜单中的单个项目。或者，正如文档所描述的:
An implementation of an item in a menu. A menu item is essentially a button sitting in a list. When the user selects the "button", the action associated with the menu item is performed.
