Utility class

From Wikipedia, the free encyclopedia

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 [1] which provides several utility methods (such as sorting) on objects that implement a Collection (java.util.collection [2] ).

• Utility Pattern: For a utility class, which does not require instantiation and only has static methods, use a private constructor
