What is isWeak method of DESKeySpec class doing?

[Question.1]
According to JavaDoc, isWeak method of DESKeySpec is checking if the given DES key material is weak or semi-weak.
What is the method checking concretely?
What do weak and semi-weak mean?

[Question.2]
I want to do the same check for AES key, but there isn't AESKeySpec class like DESKeySpec.
Are there any ways to implement the check without isWeak method?
