java.lang.InstantiationException

tip

This happens when you try to instantiate a class that can't be instantiated, either because the class object is abstract, an interface, an array class, a primitive type, void, or because the class has no nullary constructor.

You have a different solution? A short tip here would help you and many other users who saw this issue last week.
