Q. I have now learned Java. Can I take this course?
This course is recommended for those who have created a bulletin board using Spring. It is recommended that you take this course after creating a bulletin board using Spring.
Q. Will this course help me deal with all concurrency issues?
Since each situation has a different way of handling it, it is not possible to handle everything. However, since you learn what concurrency issues are and how to solve them, I think you will be able to develop a method to apply them depending on the situation.
