Primitive to Wrapper 

Apache Commons BeanUtils is a java library useful for accessing bean properties and methods. It provides introspection capabilities to view and manipulate the properties and operations provided by the given class. This requires the libraries commons-beanutils-1.8.3.jar, commons-beanutils-bean-collections-1.8.3.jar, commons-beanutils-core-1.8.3.jar, commons-collections-3.2.1.jar, commons-logging.jar to be in classpath. The following example shows using MethodUtils.getPrimitiveWrapper() API. It returns the wrapper object class for the given primitive type.
