How to handle events in J Table (Enter event)

Question

I created a J Table having multiple rows and columns. I want to have the event to happen on second column, on entering the code on first column, and then pressing ENTER.
Eg:
first column i enter code : say A010
In the code master, the description matching the above code is "HIGH TENSION CABLE".
When I enter "A010" in the first column and press "ENTER", i want the description to appear in the second column i.e. HIGH TENSION CABLE (by referring the code master, which I already created).
How this can be handled. Please help me with the code/suggestions. As this urgently required for me in a project, I request the FORUM to help at the earliest.
Thanking you in advance.
PS: I shall appreciate if the reply is also sent to my email id: "[email protected]".

This code would do your work
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
public class TestTable
    private JTable table;
    private AbstractTableModel model;
    private DefaultTableModel defaultModel;
    private JScrollPane jsp;
    public TestTable()
        table = new JTable();
        defaultModel = new DefaultTableModel(10,5);
        setModel(defaultModel);
        jsp = new JScrollPane(table);
        hookSetTextOnEnter();
    protected void hookSetTextOnEnter()
        String actionName = "selectNextRowCell";
        final Action enterAction = table.getActionMap().get(actionName);
        Action myAction = new AbstractAction()
            public void actionPerformed(ActionEvent e)
                int row = table.getSelectedRow();
                int column = table.getSelectedColumn();
                System.out.println(" SELECTING NEXT ROW "+row+""+column);
                if(row != -1 && column == 2 )
                    Object value = table.getValueAt(row,column);
                    if(value != null && value.toString().equals("A010"))
                    table.setValueAt("HIGH TENSION CABEL",row,column+1);
                enterAction.actionPerformed(e);
        table.getActionMap().put(actionName,myAction);
    public void setModel(TableModel model)
        table.setModel(model);
    public JScrollPane getScrollPane()
        return jsp;
    public JTable getTable()
        return table;
    public static void main(String[] args)
        TestTable tt = new TestTable();
        JFrame frame = new JFrame("Test Table");
        frame.getContentPane().add(tt.getScrollPane());
        frame.pack();
        frame.setVisible(true);
