Line 27:

= Final variables =

A '''final [[variable]]''' is [[immutable]]. It can only be assigned to once, in the constructor of its class. (Note: If the variable is a reference, thethis objectmeans that it references is still mutable; but the variable cannot be re-bound to reference another object. But the object that it references is still mutable if it was originally mutable.)

Unlike the value of a [[constant]], the value of a final variable is not necessarily known at compile time.
