In computer programming, a utility class is a class that defines a set of methods that perform common, often re-used functions. Most utility classes define these common methods under static (see Static variable) scope. Examples of utility classes include java.util.Collections which provides several utility methods (such as sorting) on objects that implement a Collection (java.util.collection ).
Famous quotes containing the words utility and/or class:
“Moral sensibilities are nowadays at such cross-purposes that to one man a morality is proved by its utility, while to another its utility refutes it.”
—Friedrich Nietzsche (1844–1900)
“Indeed, there are no easy correlations between parental ideology, class or race and “successful” child development. Many children the world over have revealed a kind of toughness and plasticity that make the determined efforts of some parents to spare their children the slightest pain seem ironic.”
—Robert Coles (20th century)
