This explanation is not convincing, considering that LinkedList also supports null list entries.

Yea ... but a simpler and (IMO) more plausible explanation is that allowing null entries is useful in a lot of cases.

ArrayList isn't called like that because it mimics an array. It is called like that because it is a list implemented as an array. Just as a TreeMap doesn't behave like a Tree.

This answer, IMO, is just plain wrong. Nulls are allowed because in Java, for better or worse, (IMO, worse) null gets used a lot to represent uninitialized or missing values. How did it get the most votes and the "accept" check? Seriously, I'm really losing faith in StackOverflow these days.

This answer is plain wrong. This is just unsupported guesswork about nulls being allowed in a list implementation. Here is a roundup of Java collections allowing/disallowing nulls; notice how it has nothing to do with similarity to arrays.
