Today, learning the concept of packaging knowledge, about automatic boxing and unpacking and other means to change the data type is very interesting, while the mutual conversion is also worth remembering, of course, in the work practice makes

The range of numbers must be considered in database design and procedures; otherwise, some problems may occur. The main consideration is overflow. For example, if the database has an integer numeric field, the data in it may expand as the business
