newInstanceOrNull

public static <T> T newInstanceOrNull(Class<? extends T> clazz,
                                      Object... params)

Create a new instance of a given class. It will search for a constructor matching passed parameters. If a matching constructor is not found then it returns null. Constructor is matching when it can be invoked with given parameters. The order of parameters is significant. When a class constructor contains a primitive argument then it's matching if and only if a parameter at the same position is not null. It throws AmbigiousInstantiationException when multiple matching constructors are found.

Type Parameters:

T - class type to be instantiated

Parameters:

clazz - class to be instantiated

params - parameters to be passed to the constructor

Returns:

a new instance of a given class

Throws:

AmbigiousInstantiationException - when multiple constructors matching the parameters
