I assume you retrieve data from a database and want to display the data in a JTable. If so forward the data to your table model and invoke fireTableDataChanged(). The old data will be cleared and replaced by the new data.

There is no direct way to sync the data in the JTable with one in the database. At least you must write some code: update the database according to data of the table's model.

Implement the setValueAt() method in your table model. In setValueAt() fire a property change to inform listeners on changes. In the listener class update your database with new values.

setValueAt() in your table model



Listen on changes in your listener class and update the database

Why use a PropertyChangeListener? With TableModelListener you can already do this. Simply listen for TableModelEvents with a type of TableModelEvent.UPDATE.

TableModelListener is definitely the better solution.
