I am a java beginner. This time I will write an overview of the jar file.
A jar file is a convenient item that combines multiple java classes and packages into a single file.
As I wrote above, the classes and packages are put together in one file, so the contents contain useful functions that can be used in development. Basically, it seems that you make the jar file yourself. Therefore, I think that the contents will be packed with the functions that I think I need. ** How to make a jar file **
Basically, it is automatically generated when creating a java project, I think it will be created in [WebContent / WEB-INF / ** lib **].

If you find something wrong, please let us know in the comments. I would like to update the contents from time to time.
