Apache Commons Primitives Java Commons Primitives Commons Primitives is a set of collection and utility classes for primitive types. The Java language has a clear distinction between Object and primitive types. A lot of functionality is provided for Object types, including the Java Collection Framework. Relatively little functionality is provided by the JDK for primitives. This package addresses this by providing a set of utility and collection classes for primitives. commons-primitives 2003-11-05 1.0
