It was great to be able to learn everything up to object-oriented programming while comparing C++ and Java, and this lecture completely cleared up the structural differences that always confused me. In particular, the parts explaining the virtual table, JVM memory structure, and the internal workings of polymorphism from a comparative perspective were truly impressive. It’s not just a simple syntax lecture, but one that helps you understand "why it was designed this way." I highly recommend it to anyone who wants to explain object-oriented programming with confidence in interviews.
