Examples/test-suite/java/director_primitives_runme.java

/*
  This test program shows a C# class JavaDerived inheriting from Base. Three types of classes are created
  and the virtual methods called to demonstrate:
  1) Wide variety of primitive types
  2) Calling methods with zero, one or more parameters
  3) Director methods that are not overridden in C#
  4) Director classes that are not overridden at all in C#, ie non-director behaviour is as expected for director classes
  5) Inheritance hierarchy using director methods
  6) Return types working as well as parameters

  The Caller class is a tester class, which calls the virtual functions from C++.
