java - how to clear JTable

Question

How can i clear the content of the JTable using Java..

Answer 1

You must remove the data from the TableModel used for the table.

If using the DefaultTableModel, just set the row count to zero. This will delete the rows and fire the TableModelEvent to update the GUI.

JTable table;
…
DefaultTableModel model = (DefaultTableModel) table.getModel();
model.setRowCount(0);

If you are using other TableModel, please check the documentation.
