Java Reflection calling constructor with primitive types

Question

I have a method in my test framework that creates an instance of a class, depending on the parameters passed in:

public void test(Object... constructorArgs)          


        

Answer 1

If primitive int value is autoboxed into Integer object, it's not primitive anymore. You can't tell from Integer instance whether it was int at some point.

I would suggest passing two arrays into test method: one with types and another with values. It'll also remove ambiguity if you have a constructor MyClass(Object) and pass string value (getConstructor would be looking for String constructor).
Also, you can't tell expected parameter type if parameter value is null.
