Line 44: } Immutability of variables has great advantages, especially in optimization. For instance, Sphere will probably have a function returning its volume; knowing that its radius is constant allows us to [[memoize]] the computed ~~value of the sphere~~volume. If we have relatively few Spheres and we need their volumes very often, the gain might be substantial. Making the radius of a Sphere final informs developers and compilers that this sort of optimization is possible in all code that uses Spheres. [[Category:Java programming language]]
