  - ### Method Detail

    - #### getAccessibleChildrenCount

          public int getAccessibleChildrenCount()

      Returns the number of accessible children in the object. If all of the children of this object implement Accessible, than this method should return the number of children of this object.
      Overrides:
        `getAccessibleChildrenCount` in class `JComponent.AccessibleJComponent`
      Returns:
        the number of accessible children in the object.

    - #### getAccessibleChild

          public Accessible getAccessibleChild(int i)

      Returns the nth Accessible child of the object.
      Overrides:
        `getAccessibleChild` in class `JComponent.AccessibleJComponent`
      Parameters:
        `i` - zero-based index of child
      Returns:
        the nth Accessible child of the object
      See Also:
        `AccessibleContext.getAccessibleChildrenCount()`

    - #### getAccessibleRole

          public AccessibleRole getAccessibleRole()

      Get the role of this object.
      Overrides:
        `getAccessibleRole` in class `JMenuItem.AccessibleJMenuItem`
      Returns:
        an instance of AccessibleRole describing the role of the object
      See Also:
        `AccessibleRole`

    - #### getAccessibleSelection

          public AccessibleSelection getAccessibleSelection()

      Get the AccessibleSelection associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleSelection interface on behalf of itself.
      Overrides:
        `getAccessibleSelection` in class `AccessibleContext`
      Returns:
        this object
      See Also:
        `AccessibleSelection`

    - #### getAccessibleSelectionCount

          public int getAccessibleSelectionCount()

      Returns 1 if a sub-menu is currently selected in this menu.
      Specified by:
        `getAccessibleSelectionCount` in interface `AccessibleSelection`
      Returns:
        1 if a menu is currently selected, else 0

    - #### getAccessibleSelection

          public Accessible getAccessibleSelection(int i)

      Returns the currently selected sub-menu if one is selected, otherwise null (there can only be one selection, and it can only be a sub-menu, as otherwise menu items don't remain selected).
      Specified by:
        `getAccessibleSelection` in interface `AccessibleSelection`
      Parameters:
        `i` - the zero-based index of selected children
      Returns:
        the i-th selected child
      See Also:
        `AccessibleSelection.getAccessibleSelectionCount()`

    - #### isAccessibleChildSelected

          public boolean isAccessibleChildSelected(int i)

      Returns true if the current child of this object is selected (that is, if this child is a popped-up submenu).
      Specified by:
        `isAccessibleChildSelected` in interface `AccessibleSelection`
      Parameters:
        `i` - the zero-based index of the child in this Accessible object.
      Returns:
        true if the current child of this object is selected; else false.
      See Also:
        `AccessibleContext.getAccessibleChild(int)`

    - #### addAccessibleSelection

          public void addAccessibleSelection(int i)

      Selects the `i`th menu in the menu. If that item is a submenu, it will pop up in response. If a different item is already popped up, this will force it to close. If this is a sub-menu that is already popped up (selected), this method has no effect.
      Specified by:
        `addAccessibleSelection` in interface `AccessibleSelection`
      Parameters:
        `i` - the index of the item to be selected
      See Also:
        `AbstractButton.AccessibleAbstractButton.getAccessibleStateSet()`

    - #### removeAccessibleSelection

          public void removeAccessibleSelection(int i)

      Removes the nth item from the selection. In general, menus can only have one item within them selected at a time (e.g. one sub-menu popped open).
      Specified by:
        `removeAccessibleSelection` in interface `AccessibleSelection`
      Parameters:
        `i` - the zero-based index of the selected item
      See Also:
        `AccessibleContext.getAccessibleChild(int)`

    - #### clearAccessibleSelection

          public void clearAccessibleSelection()

      Clears the selection in the object, so that nothing in the object is selected. This will close any open sub-menu.
      Specified by:
        `clearAccessibleSelection` in interface `AccessibleSelection`

    - #### selectAllAccessibleSelection

          public void selectAllAccessibleSelection()

      Normally causes every selected item in the object to be selected if the object supports multiple selections. This method makes no sense in a menu bar, and so does nothing.
      Specified by:
        `selectAllAccessibleSelection` in interface `AccessibleSelection`
