包路径：java.awt.event.ActionEvent
类名称：ActionEvent
方法名：getActionCommand

ActionEvent.getActionCommand介绍

[英]Returns the command string associated with this action. This string allows a "modal" component to specify one of several commands, depending on its state. For example, a single button might toggle between "show details" and "hide details". The source object and the event would be the same in each case, but the command string would identify the intended action.
[中]返回与此操作关联的命令字符串。此字符串允许“模态”组件根据其状态指定多个命令之一。例如，单个按钮可能会在“显示详细信息”和“隐藏详细信息”之间切换。源对象和事件在每种情况下都是相同的，但命令字符串将标识预期的操作。
