I added a keyListener event to one JTable "table1", and i implemented the method keyReleased. now my requirement is when i edit row data of table1 and when i press enter key, one new row should added to another JTable "table2". i implemented the code as below its working perfectly when i press enter key first time and one row also added to table2 ,but when i press enter key second time, the corresponding function calling two times and two rows are added into table2 .

i implemented the code as follows

jTable1.addKeyListener(new java.awt.event.KeyAdapter() {

public void keyReleased(java.awt.event.KeyEvent ke){
if(ke.getKeyCode()==KeyEvent.VK_ENTER){

javax.swing.table.DefaultTableModel d1=(javax.swing.table.DefaultTableModel)jTable2.ge tModel();
d1.addRow(new Object[]{(String)jTable1.getValueAt(jTable1.getRowCount()-1,0)});
jTable2.updateUI();
);


please help me.

Thanks in advance,

Can't know the source of your stated problem without an SSCCE (Short, Self Contained, Compilable and Executable) example, but why on earth are you invoking updateUI() ? Did you even take a look at the documentation for the method?
Notification from the UIManager that the L&F has changed. Replaces the current UI object with the latest version from the UIManager.

Another note: Wherever possible, use key bindings, not a KeyListener.

I think you have register the key listener 2 times. Add a debug out on the place where you register the listener.
