jTable wrong Rownumber after navigate with up / down Keys

To get the selected row in a jTable, I used a MouseEvent (MouseClicked). That works fine and give me the correct rownumber after clicking into the table.

To navigate trough the jTable, I added a new Listener (KeyPressed). If I press the up key, the rownumber is not been increased. If I press the up key again, the rowcount will be updated, but it is the rowcount from previously.

private void jTable1KeyPressed(java.awt.event.KeyEvent evt) { 
    if(evt.getKeyCode() == evt.VK_UP){
     System.out.println("Key UP" + jTable1.getSelectedRow()); 
    } 

    if(evt.getKeyCode() == evt.VK_DOWN){ 
    System.out.println("Key DOWN" + jTable1.getSelectedRow()); 
    }
}

This is the simple code. If I click into first row of table and press the down key, the output is "Key DOWN0". But the second row is selected and output should be "Key DOWN1".
