Why are these two ways to associate a GUI element with an action different from their results?

Question

I am currently studying this tutorial.

The tutorial describes two different ways to map a text editing command (instance Action) to a GUI element.

---

Option 1:

Get an array containing all available actions from a specific JTextComponentone by calling component.getActions(). After that, sort them by name in HashMap and enter a method that takes a name and returns an action from HashMap.

Then, the mapping of the GUI element to the action on the JTextComponent is performed, as in the following example:

JMenu menu = new JMenu("Edit");
...
menu.add(getActionByName(DefaultEditorKit.cutAction));

Option 2:

Initiate an action directly, and then associate a GUI element with it. For instance:

JMenu menu = new JMenu("Style");

Action action = new StyledEditorKit.BoldAction();
action.putValue(Action.NAME, "Bold");
menu.add(action);
...
