what is it precisely that you mean?
you get an object of that class and call the methods on that object

you can get an intance by calling Scollable.getVericalBar for example
(you don't create those objects but that does mean you cannot aquire one from someone else)

Please read ScrollBar's Java Doc. It gives an explanation why ScrollBars
cannot be instantiated and that you'll have to use a Slider instead:

"Note: Scroll bars are not Controls. On some platforms, scroll bars that
appear as part of some standard controls such as a text or list have no
operating system resources and are not children of the control. For this
reason, scroll bars are treated specially. To create a control that looks
like a scroll bar but has operating system resources, use
<code>Slider</code>.
