1.1 Algorithms
Informally, an algorithm is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. An algorithm is thus a sequence of computational steps that transform the input into the output.
Item 1: Consider static factory methods instead of constructors
The normal way for a class to allow a client to obtain an instance of itself is to provide
a public constructor. There is another technique that should be a part of every
programmer’s toolkit. A class can provide a public static factory method, which is
simply a static method that returns an instance of the class.

THIS chapter concerns creating and destroying objects: when and how to create them, when and how to avoid creating them, how to ensure they are destroyed in a timely manner, and how to manage any cleanup actions that must precede their destruction.
