在java中发生事件后ActionEvent创建的什么对象，该对象和事件源有什么区别

创建ActionEvent对象啊，这个对象可以获取到事件源，事件源是一个控件，比如按钮，这只是一个事件对象

事件源：由它们来引导相应事件的发生
Action创建的对象：当特定于组件的动作（比如被按下）发生时，由组件（比如 Button）生成此高级别事件

/**
* A semantic event which indicates that a component-defined action occurred.
* This high-level event is generated by a component (such as a
* <code>Button</code>) when
* the component-specific action occurs (such as being pressed).
* The event is passed to every every <code>ActionListener</code> object
* that registered to receive such events using the component's
* <code>addActionListener</code> method.
