keep first row in jtable selected as default

Question

table.setRowSelectionInterval(0, 0);

I had tried the above code, but when I use this code I cannot retrieve the values using the below code:

int col = table.getSelectedColumn();
int row = table.getSelectedRow();
finalOID=(String)table.getModel().getValueAt(row, col);
System.out.println("first oid:"+finalOID);

How can I solve this?

Answer 1

have look at method for JTable

table.changeSelection(0, 0, false, false);

depends of Selection Mode

method must be invoked on Event Dispatch Thread, more in the Oracle tutorial Concurency in Swing
