Upon instantiation, each object is passed a table model object that manages the data it displays. By default, a JTable object inherits a DefaultTable object if no custom TableModel object is specified, but by default, this model only manages strings. To handle objects, perform calculations, or to retrieve data from databases or other programs, you must design your own custom TableModel object, which implements the TableModel interface. See for details. To detect changes to the data managed by a table model object, the JTable class needs to implement the TableModelListener interface, call addTableModelListener() to catch events, and then override tableChanged() to respond to listener events. See for details.
