How to instantiate class in Java where number of parameters in constructor of class under test is unknown through Reflection?

Question

Using Reflection in Java, I want to instantiate a class where number of parameter in constructor is unknown. Can it be done?

Answer 1

 Constructor[] ctors = Test1.class.getDeclaredConstructors();
 for (Constructor constructor : ctors) {
        System.out.println(constructor);
 }

If you test you will see that all constructors are showed, with there parameters and which object you need to pass.

To have the paramets types do:

 Class[] clz = constructor.getParameterTypes();

So I guess the answer is Yes.
