此Bits类与Bitset之间的区别

Question

I have a question on the differences between the Bits class from the LibGDX library and the BitSet class in the standard Java library. Was the Bits class built to be faster in handling bitwise operations or more memory efficient?

Answer 1

I believe this is the source of that class. Here's the source of BitSet . At a glance they're very similar; they're both backed by long[] s. I would not expect any particular improvement in performance. You can use whichever you'd prefer, though I'd err on the side of the JDK implementation as more standard.

It's somewhat odd that the class doesn't even mention the JDK's BitSet (such as a "This class performs better/worse than BitSet in such-and-such case") which makes me wonder if the implementors simply didn't look for such a class in the JDK before creating theirs.
