public final class ReflectUtilities

extends java.lang.Object

Class Objects is a collection of small helper methods concerning "integral type to Object" conversions and dynamic method invocation. Basically this class was added for beautification purpose: By using Objects.get(integraltype) you can avoid code lines like this: Double d = new Double(myIntegralDouble).
