I was getting bored just listening to the Java basics in lecture form and studying, but I found it more fun to study by finding what I needed while making it. 
You can watch it on YouTube, but 
I recommend checking the requirements and pre-learning content in advance on the Inflearn dashboard and watching it after pre-coding.

<Code Squad Playground> is a preparatory step for taking the Masters Course White Level. This course is for those who have never experienced coding. Rather than learning theories based on the existing theory, you will learn theories while creating something. Even if you do not take the Masters Course White Level, those who are starting to learn Java programming are encouraged to try it.
