JDBC update changes to JTable.

So far what I have been wondering:

- I have somehow finished the beginner level of JTable step by step
following the official tutorial.
- I know how to use JDBC to query/update/ delete PostgreSQL database
records.
- Add a button to update and insert and delete database table.

After using *select *syntax to populate JTable, I wonder how to update
changes made in JTable to the database.
After browsing StackOverFlow, I have some basic idea:

- Step 1: editing
- step 2: stop editing;
- Step 3: make the update sync with the database.

Step1 is about adjusting the DefaultTableModel by calling related methods
as per requirement. Related link: DefaultTableModel (Java Platform SE 7 )
(oracle.com)
<https://docs.oracle.com/javase/7/docs/api/javax/swing/table/DefaultTableModel.html>

Step2: I copied from StackOverFlow (
https://stackoverflow.com/questions/12823475/what-is-the-best-way-to-listen-for-changes-in-jtable-cell-values-and-update-data
)

Step3: I don't know how to do it. So I asked the question on
StackOverFlow (java - Update changes In JTable to database? - Stack Overflow
<https://stackoverflow.com/questions/68149156/update-changes-in-jtable-to-database>)
If you guys know how to do it, please help me.

I know it's less about JDBC, more about Java. Anyway.................
