Java Stanford NLP: Part of Speech labels? -

The Stanford NLP demo gives an output like this:

  Colorless / JJ Green / JJ thoughts / NNS sleep / VBP badly / RB ./  

What part of the speech tag mean? I can not find an official list, is it Stanford's own system, or are they using the universal tag? (For example, what is j j ?)

Besides, when I'm walking through sentences again, for example, looking for the nouns, let me Something like checking the view is .contains ('N') . It looks very weak, is there a better way to programmatically search for a better speech?
