I am planning to attend a nationally funded Java course in the future, so I took the introductory class once, and it was really easy to teach, and it was fun to learn, and I liked the words that gave me confidence here and there. I highly recommend it to anyone who wants to get a taste of what kind of computer language program Java is for a day or two. I somehow got the book, so I'm going to look into it diligently. Thank you, instructor, for giving a good pre-class for beginners for free ^^
