Oracle Software Developer interview questions

It was just an phone interview[I didn't pass]. I applied online. The HR was very nice. They ask me on the phone a lots of question about my experince. They ask me technical question about Object Oriented Programing. What is a copy constructor? When should I use private inheritence? Sort me a array. I must say that it was an interview for a junior position. I wasn't prepared to that time, to young.
