❗ Errors❗☑️ in JDBC MySQL CONNECTIVITY Netbeans



DOWNLOAD LINK :-

I have JDBC connectivity issue in NETBEANS from long time though code was totally fine.
I resolved by removing the default driver (Connector/J driver) from the driver list under databases/drivers.

1. java.math.BigInteger cannot be cast to java.lang.Long. 

2. unable to catching sha2 password or caching_sha2_password

3. Code have no errors but GUI Doesn’t work with Back end database application

4. Main Class Missing while GUI
A common problem that new Java developers experience is that their programs fail to run with the error message: Could not find or load main class ..
how should you fix it?

5. Database remains disconnected after putting password

6. jOptionPane showing errors

7. Important import files

The major issue solved here is almost related to problem in given link below
