i am facing the problem while i am running my project. The situation is, i have a button which let me to print the output in the table. However, every time i click on the button, the table is appending rather than replacing the old value. For jtextarea i solved it using a simply way which is use jtextarea.settext rather thn jtextarea.append. This is how i passing the value in to the table DefaultTableModel model = (DefaultTableModel) jTable1.getModel(); model.addRow(row); i declare row as vector. Can anyone tell me how to make it replace the value rather than append.

    [`TableModel#setValueAt`](https://docs.oracle.com/javase/7/docs/api/javax/swing/table/TableModel.html#setValueAt(java.lang.Object,%20int,%20int)). Consider providing a [runnable example](https://stackoverflow.com/help/mcve) which demonstrates your problem. This is not a code dump, but an example of what you are doing which highlights the problem you are having. This will result in less confusion and better responses – MadProgrammer Jan 07 '16 at 04:56

    You could use a combination of [`DefaultTableModel#removeRow`](https://docs.oracle.com/javase/7/docs/api/javax/swing/table/DefaultTableModel.html#removeRow(int)) and [`DefaultTableModel#insertRow`](https://docs.oracle.com/javase/7/docs/api/javax/swing/table/DefaultTableModel.html#insertRow(int,%20java.util.Vector)) to replace the existing row – MadProgrammer Jan 07 '16 at 04:58

As shown here, invoke setRowCount(0) to clear the table's model and then model.addRow(row) to add a new row.
