- SQL

solved 1 problem. It left about 3 questions. They are going to be done in this week :)

I am still uncomfortable with SQL but it gets much more familiar to me.

 

- Woowa Course

I got much questions from class on Morning. Through meeting with coach, I needed to think about plans for advance. 😉

 

On afternoon, I spent almost time for refactoring Blackjack mission. I tried to rebuild structure. I think it gets better but I am not sure that it is good enough.

 

[ Apply ]

Every meaningful primitive type is wrapped as Object.

In constructor, every parameter is Object.

--> they makes me concentrate on only one role and responsibility of every Object.

 

I tried to apply State Pattern but I failed. I am still curious that the pattern is needed for what.

 

Tomorrow, I am going to study State Pattern again to apply on my mission. 😉
