This is Java programming organized in 815 minutes! The voice really suits the lecture, and each class goes over the concepts without long explanations. Maybe that's why Java, which was difficult to learn, was completely organized in my head! All of this great content for only 11,000 won! Thank you, teacher!! 1. Those who see 200% results when learning - Those who have been exposed to other languages and are new to Java. - Those who have learned Java but are not able to organize it 2. Those who see 50% results when learning - Those who have never been exposed to programming before. This lecture is a lecture that simply organizes concepts, so if you are new to it, you may feel that the lecture speed is fast and it may be difficult to understand. Be careful! 3. Pros - Java summary in 815 minutes - Clean class and summary as if you are taking a 1:1 private lesson. I want to take a class like this later! 4. Cons - This is an old version lecture that covers Java 6. There is no famous Stream API either.. so if you want to take "Modern Java", you will have to look for other lectures.
