LOL, she's rich & (in)famous, can afford to buy expensive gadgets like a PS4 and Xbox One for her sons, graduated from a high-end university, is a self-declared "Queen of All Media", appears to be a social media user--which means she knows how to use PCs .... and she doesn't know what Java is until now?
If you've been using PCs or a web browser since the mid-1990s, then surely you would have at least encountered it or heard about it in some form or another, as web browsers constantly ask you for Java updates.
All those expensive gadgets she owns, and she can't spare several seconds to Google what Java is? Or even ask any of her writers what Java is? Hilarious.
