I am new to OOAD and want to know what is the best way i can start learning. I am pretty comfortable with languages like java and C++ but have been doing programming more or less in the C style.Some how i am not too comfortable with real OOP and design for a given problem.I recently cleared SCJP and now wish to appear for IBM 486 test i think preparing for this test will serve as a vehicle for learning OOAD what do you guys have to say about it ?
