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

Use Integer.TYPE instead of Integer.class.

As per the Javadocs, this is "The Class instance representing the primitive type int."

You can also use int.class. It's a shortcut for Integer.TYPE. Not only classes, even for primitive types you can say type.class in Java.
