I have to read an Excel file and transfer the contents to the database using Java swing.The excel file contains questions for the surveys with options for answers or responses.The database should have a table say Question with columns "Question No., Question, Option 1, Option 2 and so on".I have this code snippet with which I am able to read the excel file and display its contents on the console but I am unable to transfer the content to the database using SQL.Could you please help me in doing what I need.Provide a code for doing that.

Swing does not interact with a DB. It's used to create a user interface (frames, panels, well, your basic screens) in which you can enter or show information.

where Swing can help you create the code for your front-end, the actual calls to your DB are more in the back-end of your application.

you'll need to look into the use of JDBC.
