How can I change the content of JTable?

Question

Dear friends.
I have an JTable. I create tablemodel for it and fill out it by data.
In application at the run time I always need to change the content of whole table. For example I have a frame with JTree and JTable. When I click on the tree node I need to retrieve the data about this node in the JTable.
Advice me please how can I do that and give an example please.
Thank you.

SOL I:
There solution can be simple if u've written a model for it.
If u are updating the data of the table by the setValueAt() method of the tableModel, in ur calling(mutating code), then just append a sinle line at the end of the method. U just need to fire a data change event corresponding to the event that has happened.
void setValueAt(Object aValue, int rowIndex, int columnIndex) {
- - - - - - - ur code
//then last line can be
fireTableDataChanged() ;
OR
fireTableCellUpdated(int row, int column);
OR
fireTableStructureChanged() ;
depending uopn what has happened.
SOL II:
U may also try calling the method fireTableDataChanged(); from the place where the table data is getting mutated.
like:
((AbstractTableModel) table.getModel()).fireTableDataChanged();
