static Method	getMethod(Class<?> clazz, String methodName, Class<?>... parameterClass)
static Method	getMethodElseNull(Class<?> clazz, String methodName, Class<?>... parameterClass)
static Object	getNullOrDefault(Class<?> type) Returns the corresponding 'null' value for the primitives, or just null if the class represents a non-primitive type.
