java - Can I Instantiate a class using the class object? What about Constructors?

I am storing a list of classes through (Classname.class) and would like to instantiate one? Is this possible?

newInstance seems to the method I am after but it doesn't support a constructor?

You can use Class.getConstructors (or Class.getConstructor) to get a list of available constructors, and invoke any of them with Constructor.newInstance, which does accept parameters.
