1. I wrote a class PUPLIC_A to implement an interface ITF_B that helps me to access to a class CLASS_C which has private access (because I can not access this class directly. 2. In PUPLIC_A, I implement a method ITF_B1(String string, CLASS_C class_C)to do some works for me. 3. I wrote another class in another file to access class PUBLIC_A and call its method ITF_B1. But when I try to create an instance of CLASS_C to pass to ITF_B1 as its second parameter using operator "new". It failed to do so because CLASS_C can not be instantiated or accessed directly. Is there any other ways to do this. Thanks in advance for any help. PhiDi TranThi    More>>
