Why do different java collections have different default capacity?
Looking at different collection constructors the question comes to mind. Why does ArrayList()
construct an empty list with an initial capacity of ten and ArrayDeque()
constructs an empty array deque with an initial capacity sufficient to hold 16 elements.

How can a collection class instantiate many objects with one database call?
I have a baseClass where I do not want public setters. I have a load($id) method that will retrieve the data for that object from the db.

Is throwing an error in unpredictable subclass-specific circumstances a violation of LSP?
Let’s say I wanted to create a Java List<String> (see spec) implementation that uses a complex subsystem, such as a database or file system, for its store so that it acts as a persistent collection rather than an in-memory one.
