IMHO, if you've crossed your schooling try to learn it yourselves. Again, that's my opinion. Take help from books, if needed. There is so much material to learn out there, that you just need to learn to find/filter study materials and start learning at your own pace.
That said, If you still need any materials, there are lot of videos in you tube too to learn the basics in OCPJP.
Not sure if there are any video lessons in java ranch. I will leave it to the moderators to answer that.
If you are not laughing at yourself, then you just didn't get the joke.
