It is no exaggeration to say that I came to like Java thanks to this lecture. In particular, Mr. Ki-seon is the first person who explained streams and functional interfaces so easily. Thanks to him, I, who always gave up on coding tests in Java without even trying, ended up studying coding tests in Java. There is some feedback that it feels insincere, but I liked Mr. Ki-seon's indifferent tone, as if Java doesn't need to be difficult, because it relieved the burden I had about Java. After listening to this, I also bought Effective Java 1, 2 and Code Manipulation!! Thank you, King God General Mr. Ki-seon. Thank you 🥹🥹
