If it has an accessible default constructor:
Class.forName("my.class.Name").getConstructor().newInstance()
otherwise you'll need to pass in the constructor arguments types and
the arguments itself
Don't use:
Class.forName("my.class.Name").newInstance()
although shorter it propagates any exception thrown by the
constructor, including checked ones. You don't want this.
