make sure uou dont put the conmection inside try () bracket cause then it closes the Autocloseable after try catch block
like in this case if you have sth like this:
try (connection =...) or somwthing with connection inside gjis bracket, remove it from yhere
Thank you very much, although I'm still a little confused because I'm doing my work internship, but it's actually a requirement to graduate and I don't have much idea about programming, so I did it with an AI, I don't know if I could send you the code to find out
Note that you are probably not allowed to just share code you wrote for your company with others
Essentially, a JDBC
Connection object is valid only until you call the close() method on it
you should call close() on it as soon as you don't need it any more (make sure to not forget about it) - but not before that
Also make sure you are actually understanding all the code you are writingThanks, I'll see if I can finish the practice.
