Take the answer ：

url There is a mistake here
What you're writing is ：String url="jdbc:mysgL;//Localhost:3306/atm"
The right one is ：String url="jdbc:mysql://localhost:3306/atm"
If there is a garbled code problem, write it as ："jdbc:mysql://localhost:3306/atm?UseUnicode=true&CharacterEncoding=true"
