Cannot refer to a non-final variable i inside an inner class defined in a different method
在内部类中不能引用一个定义在不同方法中的非final的变量i（翻译能力有限）
for(int i = 0; i < buttonIconList.size(); i++) {
//Adding the shadow when the mouse cursor is on
buttonIconList.get(i).addEventHandler(MouseEvent.MOUSE_ENTERED,
new EventHandler<MouseEvent>() {
@Override public void handle(MouseEvent e) {
buttonIconList.get(i).setEffect(shadow);
}
});
}
如果把i定义成final, buttonIconList.get(i).setEffect(shadow);这行就不报错了。可是i定义成final了，就不能循环了吧？如何解决呢?
